            <p> Synonymy.  Sida crystallina ortiva Korovchinsky, 1979 , p. 1785–1786, Fig. 2: 1–2, 7, 9, 12; Korovchinsky 2004, p. 253, Fig. 79: 4, 6, Fig. 80: 2, 5; Kotov et al. 2011b, p. 404. </p>
            <p>Type locality. “The Amur River near mouth of the Sungari River”, Jewish Autonomous Area, Russia (Korovchinsky 1979). Coordinates: approximately 47.7ºN, 132.5ºE.</p>
            <p>Localities in Korea. 1, 10, 11 (see Fig. 1 and Table 1).</p>
            <p> Parthenogenetic female. Body ovoid, head small, with a large anterior and a pair of smaller anchor organs (Fig. 2 A, arrows) dorsally, dorsal margin convex, postero-dorsal angle expressed, posterion margin straight, postero-ventral margin expressed, bearing a spine. Rostrum relatively short, directed ventrally, compound eye large, situated near ventral head margin, ocellus very small (Fig. 2 B). Posterior valve margin with a row of numerous marginal spinules (Fig. 2 C). Postabdomen trapezium-shaped, comparatively short; ventral margin straight, preanal margin long, straight, anus opens distally (Fig. 2 D–E). Row of 12–14 anal teeth along each lateral side, rows of minute spinules near these teeth. Postabdominal claw regularly bent, with four basal spines, proximal most spine only somewhat smaller than next spine (Fig. 2 E). Postabdominal setae long, about 0.4 of body length, located on a strong projection. Antenna I long, with distal aesthetascs and distal sensory seta longer than the former (Fig. 2 F). Antenna II long, basal segment long, with some spines distally (Fig. 2 G). Antennal formula in our material: setae 0 −4-7/ 0−1−4. Six pairs of thoracic limbs, not different from those in  S. crystallina described by Korovchinsky (2004). Size in our material 1.5–2.4 mm. </p>
            <p> Notes.  Sida crystallina ortiva Korovchinsky, 1979 was established at the subspecies rank. But preliminary molecular phylogenetic studies suggest deep divergence with  S. crystallina (O.F. Müller, 1776) (Kotov &amp; Taylor, unpublished).  Sida crystallina is widely distributed in the Western Palaeractic and penetrates Eastern Palaearctic up to Far East;  S. ortiva is present in Siberia, Far East of Russia and more southern areas of eastern and south-east Asia (Korovchinsky 2004; Kotov et al. 2011b). Both species are found in South Korea.  S. crystallina was found by us in localities 3 and 12, see Fig. 3 A–G, and was illustrated by Kim &amp; Yoon 1987, Fig. 2 a–e and Yoon 2010, Fig. 18 B. It differs from  S. ortiva mainly in (1) longer rostrum projected posteriorly; (2) proximal most basal spine on postabdominal claw significantly shorter than the next spine and located close to it. </p>

            <p>Parthenogenetic female. Body ovoid, elongated, head small, dorsal margin convex, postero-dorsal angle expressed, posterior margin convex, postero-ventral margin strongly projected (Fig. 4 A). Rostrum directed ventrally, compound eye large, situated near antero-ventral head margin, ocellus small (Fig. 4 B). Setae at anteroventral portion of valve relatively short, not specially elongated and modified (Fig. 4 C). Posterior valve margin with an inner row of numerous submarginal spinules and clusters of smaller spinules. Postabdomen subrectangular, comparatively short; ventral margin straight, preanal margin long, concave with a projection near anus, "terminal outgrowth" in terminology of Korovchinsky (2011) (Fig. 4 D). Row of 10−12 clusters of anal teeth along each lateral side, mostly with 3−6 teeth in each cluster; rows of minute spinules near clusters of anal teeth. Groups of comparatively large spines laterally to postabdominal claw base (Fig. 4 E). Postabdominal claw regularly bent, with three basal spines, two of which are long and proximalmost one very small. In a single female there were two very small spinules in position of proximal basal spine (Fig. 4 D), numerous large spinules distally on ventral side of the claws (Fig. 4 E). Postabdominal setae long, about 0.54 of body length. Antenna I long (Fig. 4 A–B), with aesthetascs on a small lateral prominence in its middle; distally a large sensory seta armed with long setules (Fig. 4 F). Antenna II long, basal segment long, with a spine in its distal portion between branches and a denticle laterally (Fig. 4 G). Exopod bisegmented, proximal segment distally with a large spine and a large denticle; distal segment with a small prominence proximally and a large spine with small hillock near it distally (Fig. 4 H). Endopod three-segmented, second segment long and stout, apically with a long seta and a short spine, apical segment with three setae and a spine. Antennal formula in our material: setae (5−7) − (10−11) / 0−1−3. Six pairs of thoracic limbs, as described by Korovchinsky (2010). Size in our material 1.22–1.75 mm.</p>
            <p> Notes. Korovchinsky (2010) pointed out that previous Asian records of  P. bidentata Herrick, 1884 are dubious, and these populations in reality belong to  P. szalayi . The latter is found in Sri Lanka, India, Bangladesh, China and Amur basin in Far East of Russia (Korovchninsky 2010). So, its presence in Korea was quite expected. We provide the first record of the genus for Korea. </p>

            <p>Parthenogenetic female. Brownish in colour. Body with dorsal margin interrupted by a cervical incision, postero-dorsal angle well-expressed, posterion margin slightly convex, postero-ventral angle with a strong spine - mucro, which is of 0.2 of valve length (Fig. 5 A). Head rather large, lacking a horn, rostrum trilobate in ventral view (Fig. 5 B), middle lobe with "a hyaline membrane in front" in terminology of Dumont &amp; Pensaert (1983), compound eye very large, occupies distalmost portion of head (Fig. 5 A). A ridge departs from the insertion of the second antenna and extends to the side of the head—seen frontally, it appear as a pair of shallow depressions, "auricles" in terminology of Dumont &amp; Pensaert (1983). An elongate frontal head pore on the rostrum (Fig. 5 B, arrow). Valves with reticulations as vertical lines near the posterior margin. A projection on ventral valve margin before the system of setae located on a flat portion, "sucker-plate" in terminology of Dumont &amp; Pensaert (1983). A broad hyaline membrane extends beyond the posterior valve rim (Fig. 5 –D). Postabdomen slightly widened distally, preanal margin long, preanal angle obtuse, anal margin straight, postanal angle not expressed, postanal margin very short (Fig. 5 E). About 3–5 single postanal teeth, followed by clusters of spinules proximally (on anal margin), numerous series of minute setules laterally (Fig. 5 F). In distal dorsal external pecten 2–4 proximalmost denticles specially strong and sparsely located. First antenna short, with antennular sensory seta and 9 terminal aesthetascs (Fig. 5 G). Antenna II long, antennal formula: setae 0-1-3/1-1-3 (Fig. 5 H). Limb I as shown in Fig. 5 I. Other limbs not studied. Size in our material 0.5–1.0 mm.</p>
            <p> Notes. According to Dumont &amp; Pensaert (1983), this taxon is distributed in Australia, SE Asia, India, Middle East and Africa. It is known from the Far East of Russia (Kotov et al. 2011b), China (Chiang &amp; Du 1979) and Japan (Mizuno &amp; Takahashi 1991), so its presence in Korea was expected. Yoon (2010) described  S. mucronata (O. F. Müller, 1776) and  S. rammneri Dumont &amp; Pensaert, 1983 from Korea, but we did not see these species in our samples. Probably this author misidentified  S. kingi as  S. rammneri . Unfortunately, descriptions and illustrations by Kim (1988), Kim &amp; Yoon (1987) and Yoon (2010) do not allow us to assign their "  S. mucronata " to any species, because most taxonomically important characters were not mentioned. </p>

            <p>Parthenogenetic female. Body subovoid, dorsal margin with a shallow cervical incision, postero-dorsal angle broadly rounded, without any projection and prominence anterior to it, posterior margin almost straight, fluently turned to ventral margin without any angle, ventral margin convex (Fig. 6 A). Head with a small rostrum; large compound eye occupies antero-ventral portion of head; ocellus small, of irregular shape (Fig. 6 B). Labrum fleshy, with a large, setulated distal labral plate. Valve with a row of numerous setae submarginally near ventral margin; in its posterior portion it turns to a row of grouped setules, with size increasing dorsally in each series (Fig. 6 C). Postabdomen with an undulated preanal margin, strongly prominent preanal angle, convex anal margin, undistinguishable postanal angle and a very small postanal margin (Fig. 6 D). Few strong, single postanal teeth, bearing minute setules (Fig. 6 E). Postabdominal claw long, slightly curved, with about 15 small, thin teeth in first (proximal) pecten, more than 20 relatively thin teeth in second pecten, and numerous fine setules in third pecten (Fig. 6 E). Antenna I short, with a strong antennular sensory seta on a special projection and nine terminal aesthetascs (Fig. 6 B, F). Antenna II long, antennal formula: setae 0-0-1-3/1-1-3, a small spine on proximal segment of exopod (Fig. 6 G). Limb I as illustrated in Fig. 6 H. Other limbs described by Orlova-Bienkowskaja (1998). Size in our material 1.5–1.9 mm.</p>
            <p> Notes. Orlova-Bienkowskaja (2001) stated that "This species was previously confused with  S. exspinosus , so its range needs to be redefined. It occurs with certainty in Central and Eastern Europe and Siberia". Recently this taxon was also found in the Far East of Russia (Kotov et al. 2011b). Most probably,  S. exspinosus (Koch, 1841) illustrated by Kim &amp; Yoon (1987) and Yoon (2010) could also be  S. congener , but the distal portion of the postabdominal claw was illustrated inadequately. At this moment, this taxon could be regarded as Palaearctic, penetrating to the South. </p>

Body subovoid, dorsal margin with a wear cervical incision, postero-dorsal angle as a rounded triangle (Fig. 7 A–B), posterior margin fluently turned to ventral margin without any angle, ventral margin convex; no hairs anywhere else on the head or valves. Body compressed laterally, with a well-expressed median keel on dorsal portion of valves. Head small, sub-triangular, with a shallow supra-ocular depression above large compound eye which fills the tip of the head; ocellus small (Fig. 7 B). Valves reticulated, ventral margin with denticles, a pair of submarginal hooks at the point where the valves come together (Fig. 7 C). Postabdomen with wide preanal and narrow postanal portions, preanal margin large and lacking long setules, preanal angle distinct, anal margin straight, postanal angle expressed, postanal margin straight (Fig. 7 D). On postanal portion, eight-nine feathered lateral teeth plus a long, bident tooth near base of postabdominal claw. Postabdominal claw long, with two pectens of thin setules. Antenna I long, cylindrical, antennular sensory seta originated somewhat proximally to its middle; nine very short aesthetascs distally (Fig. 7 A). Antenna II thin and long, basal segment with a long seta on posterior side (Fig. 7 E). Antennal formula: setae 0-0-1-3/1-1-3, spines 0-1-0-1/0-0-1. Apical spine on exopod specially long, so, it is sometimes counted as a seta (Smirnov, 1976), but we think that antennal formula as suggested here is more correct for homologization of setae and spines on antenna II on  Moinodaphnia and other anomopods. Limb I as illustrated in Fig. 7 F. Size in our material 0.7–1.2 mm. </p>
            <p> Notes. According to Smirnov (1976),  Moinodaphnia macleayi is a circumtropical species. Most probably Korea is the northernmost area of its distribution. The species is also known from China (Chiang &amp; Du 1979) and Japan (Mizuno &amp; Takahashi 1991). This is the first record for Korea. </p>

            <p>Parthenogenetic female. Body triangular-ovoid, postero-dorsal angle expressed (Fig. 8 A). In anterior view, body thick, with thick and low dorsal keel, without lateral horns. Moulting incomplete. Ocellus small (Fig. 8 B). Head shield with mandibular articulation as a small projection (Fig. 8 C). Setae at ventral margin plumose (Fig. 8 D). Each seta at posterior margin with a long, stout basal part, than with a series of 2–4 stout spine-like setules along one side in its basal portion, and with fine hairs in distal portion (Fig. 8 E). Anus opens in the middle between base and distal extremity of postabdomen; preanal teeth 10–12, subequal in size, both doubled and single in the same specimen, few denticles on postabdomen base laterally (Fig. 8 F). Paired spines shorter than large lateral setae. Postabdominal claw with a single denticle in distal part, no denticles in its middle part, distal and proximal spines on claw base subequal in size; setules situated on base of claw ventrally long (Fig. 8 G). Antenna I relatively long, with transverse ridges (Fig. 8 B). Proximal segment with a finger-like projection and few low hillocks (Fig. 8 H). The longest aesthetasc about half the distal segment. Antenna II short, distal burrowing spine relatively short, with tip almost reaching or reaching distal border of basal segment (Fig. 9 A). Both antennal branches short (Fig. 9 B–C). Apical swimming setae relatively short, armed with short setules distally (Fig. 9 D). Proximal lateral swimming seta shorter than distal one, both without hooks on tips and armed along one side with setules analogous to these of apical setae, and more stout and long setules along other side (Fig. 9 E–F). Spine on second segment of exopod equal to or somewhat shorter than half of third segment (Fig. 9 B–C). A large seta near ejector hooks of limb I. Gnathobase I as a setulated hillock. Limb VI with row of long setules along inner margin subdivided into six bundles by small incisions on the margin. Size in our material 0.61–0.83 mm.</p>
            <p> Notes. The species is widely distributed in the Northern Palaearctic and Nearctic (Kotov &amp; Štifter 2006) and found close to Korea: Japan (Tanaka 2001) and the Amur basin in Far East of Russia, where it is quite common (Kotov et al. 2011a). We found it also to be common in the Korean Peninsula, which could be the southernmost area of its distribution in Asia. Unfortunately, there is no information on its presence in China, and previous descriptions of ilyocryptids (Chiang &amp; Du 1979) are not detailed enough to separate  sordidus -like species sensu Kotov &amp; Elías-Gutiérrez (2009). Korean specimens are somewhat different from European ones in: (1) only few denticles on postabdomen base laterally; (2) ridges, although ill-expressed, on distal segment of antenna I. It is possible that populations from the Far East form a separate taxon, but this idea could be confirmed only in the course of a global revision of the  cuneatus -like populations in the Palaearctic. </p>

            <p> Notes. Two females from Bak Sil Ji were identical to those earlier found in the Amur basin (see description in Kotov et al. 2011b) and preliminarily identified as  Ilyocryptus cf. raridentatus Smirnov, 1989 . The latter species was described from Australia (Smirnov 1989). It belongs to a circumtropical  I. sarsi -group (Kotov &amp; Štifter 2006) quite common in such Asian countries like Thailand and Malaysia. The Amur basin is the northernmost border of its distribution in Asia (Kotov et al. 2011b). Some populations from this group were previously found in Japan and few localities in Far East of Russia (Kotov &amp; Štifter 2006), but their status could be checked only in the scope of a global revision of the  sarsi -group. Presence of this taxon in Korea was quite expected after findings in adjacent territories, including more northern ones in Far East of Russia. </p>

            <p>Parthenogenetic female. Body triangular-ovoid, high, dorsum almost straight, postero-dorsal angle developed (Fig. 10 A). Body compressed laterally, with well-developed dorsal keel, without lateral horns. Moulting incomplete. Head small, its ventral margin straight (Fig. 10 B). Setae at postero-ventral valve portion also very long. Each seta of ventral margin plumose, each seta posterior edge with stout spine-like setule at base and long setules distally (Fig. 10 C). Postabdomen elongated, anus opening more closely to base than to distal extremity of postabdomen (Fig. 10 D). Preanal teeth 5–11, single, relatively large, increasing in size proximally, located at approximately right angle with margin, sometimes slightly bent. A group of setules near each of teeth. Numerous, relatively robust denticles on postabdomen base. Paired spines numerous, relatively small, reaching preanal margin. Lateral setae 5–7, long, a big gap between basalmost seta and anus. Postabdominal claws long, slightly bent and with tiny denticles in distal portion (Fig. 10 E). Distal spine on claw base longer than proximal one. Setules ventrally on claw basal border short. Postabdominal setae shorter than body. Antennae I long and thin, proximal segment with big finger-like projection and system of hillocks (Fig. 10 B). Distal segment with 5–6 transverse rows of denticles, but without denticles at distal end. Two aesthetascs longer than others and longer than half the distal segment, one of them at a short distance from the rest. Antenna II long. Distal sensory seta and distal burrowing spine long, projecting behind distal end of basal segment (Fig. 10 F). Apical swimming setae long, with short setules. Both lateral setae asymmetrically feathered by short setules, with small hooks on tips. Apical spine on exopod approximately equal to spine on endopod. Length of spine on second segment of exopod shorter or equal to length of third segment. Limbs as described by Kotov &amp; Dumont (2000). Size in our material 0.81–1.04 mm.</p>
            <p> Notes. The species was initially described from Minnesota, U.S.A. (Herrick 1882a, b) and then found in many tropical and subtropical localities (Smirnov 1976; Kotov &amp; Dumont 2000). It also penetrates the Nearctic up to 47ºN (Kotov &amp; Williams 2000). The species was known from Japan (Tanaka 2001; Kotov &amp; Štifter 2006). Recently it was found in the Amur basin (51ºN), which probably is the northernmost area of its distribution in the Far East (Kotov et al. 2011a, b). Korean specimens were morphologically undistinguishable from those found in the Amur basin (Kotov et al. 2011b). From illustrations of Kim (1988), it is obvious that he misidentified this taxon from Korea as  I. agilis . </p>

            <p>Parthenogenetic female. Body subovoid, dorsal margin in general regularly curved, with well-expressed ocular dome, shallow depression behind dorsal head pore, postero-dorsal as a pointed angle, lying somewhat above longitudinal body axis (Fig. 11 A). Whole surface of head and valves covered with striae, with rare or numerous anastomousings. Body significantly compressed laterally, with sharp dorsal keel. Ventral head margin somewhat convex, with a projection anterior to labrum, which is sub-rectangular, with a series of tubercles at apex; ocellus small (Fig. 11 B). Setae at ventral margin plumose, organized in short series of three setae of different size located at different angles, the first seta thick (Fig. 11 C). Postabdomen subovoid, with rounded distal extremity, distinct heel basally, preanal margin with short transversal series of short to medium-sized setules; in basal portion these setules always longer and more robust (Fig. 11 D). Postabdominal claw small, outer dorsal row of two large denticles: a ‘basal spine’ and second denticle, plus a small denticles distally; inner dorsal row with numerous denticles, two of them remarkably more robust than the rest; ventral row of two denticles (Fig. 11 D–F). Postabdominal seta with a very short distal segment, no setules on basal segment (Fig. 11 G–H). Antenna I rod-like, sensory seta externally at a distance more than antennular diameter from antennule joint, about 7 transverse rows of denticles on anterior surface of antennule; nine short aesthetascs, two of them significantly larger than the rest (Fig. 11 B, 12A). Antenna II with two small basal sensory setae of subequal size. Basal segment with distal burrowing spine equal in length to basal segment of exopod, naked; swimming setae 0-0-1-3/1-1-3, spines 0-1-0-1/0-0-1 (Fig. 12 B). Largest seta (on basal endopod segment) with three strong spinules in middle portion, and a row of short setules in basal and distal portions (Fig. 12 C). True spine on second segment of exopod with third length of this segment. Additional spines on exopod segments small, decreasing gradually in dorsal direction (Fig. 12 B). On limb I, ODL with long apical seta, and small lateral seta; IDL with tree series of strong setules, and three bisegmented setae of different size, unilaterally setulated distally, two smaller two smaller ones hook-shaped (Fig. 12 D). Other limbs as in females from type locality as described by Dumont et al. (2002). Size in our material 0.55–0.73 mm.</p>
            <p> Notes. The  Macrothrix rosea-triserialis group was revised during the last decade, and it was found that  M. triserialis lives only in the tropics and subtropics of the Old World (Dumont et al. 2002; Kotov et al. 2004). Kim &amp; Yoon (1987) and Yoon (2010) reported for Korea only a single species from this group, the palaearctic  M. rosea (Jurine, 1820) (as  Echinisca ). We confirm its presence in Korea (see Figs 13–14 of  M. rosea from Ho Tan wetland).  M. triserialis differs from the latter in: (1) more expressed projection anterior to labrum; (2) thinner first seta in each triplet on valve; (3) very short distal segment of postabdominal seta; (4) three strong spinules in the middle of largest antennal seta. The finding of  M. triserialis in Korea‘s non-subtropical climate (i.e. winters with negative temperatures) was quite surprising. Taking into consideration that "  M. triserialis " in Fig. 192 by Chiang &amp; Du 1979 is apparently  M. rosea , the presence of  M. triserialis in China needs to be confirmed. The latter we now consider as a tropicopolitan species (=species widely distributed in the tropics, but capable of penetrating more northern territories). </p>

            <p>Parthenogenetic female. Body relatively short and wide in lateral view, dorsal margin with a weak depression anterior to brood pouch, posterior margin straight, its height less than half of body height, ventral margin almost straight, with a shallow depression anterior to mucro (Fig. 15 A). Frontal head pore small, located far from ventral margin of head shield (as seen from anterior side) somewhat dorsally to level of antennular sensory setae (Fig. 15 B). Lateral head pore small, ovoid, located in a bifurcation of reticulation near ventral margin of head shield, but not immediately near the margin (Fig. 15 C–D). Labrum a fleshy appendage lacking significant projections, distal labral plate small. Ventral valve margin with a series of stout setae on its anterior portion, base of each located on internal surface of valve, “ seta kurzi ” located on internal side of valve anterior to abovementioned depression near mucro, which is strong, relatively long and lacking any incisions (Fig. 15 E). Series of minute setules at inner side of valve near posterior valve margin. Postabdomen with width approximately equal along all its length, with ventral (although functionally dorsal) margin almost straight (Fig. 15 F). Preanal margin long, slightly convex, with groups of setules distally. Distal (anal) margin truncated, postero-dorsal angle as a projection. Postanal portion as a cylindrical projection bearing paired postabdominal claws. Each claw regularly bent, with two pectens on concave (dorsal) margin; distal pecten consists of short, fine spinules, while proximal pecten consists of 7–9 rather strong and thin teeth. Postabdominal seta shorter than preanal margin. Antenna I fused with rostrum, rather long, its length from tip to tip of rostrum less then 0.5 body lengths. Antennular (frontal) sensory seta located on rostrum. Free section of antenna I (not incorporated into rostrum) consists of a pre-aesthetasc portion, fused with rostrum, and a slightly bent post-aesthetasc portion (Kotov et al. 2009). Both portions supplied with transverse series of fine denticles. Antenna II typical for the genus, six pairs of thoracic limbs as described by Kotov (1997). Size in our material 0.34–0.40 mm.</p>
            <p> Notes. Kim &amp; Yoon (1987) and Yoon (2010) found only  Bosmina longirostris (O. F. Müller, 1776) and  B. coregoni Baird, 1857 in Korea. The most common species is  Bosmina longirostris (Fig. 16 A–C), belonging to the subgenus  Bosmina (Bosmina) Baird, 1845 . But in a single locality we found  B. fatalis belonging to the subgenus B. (Sinobosmina) Lieder, 1957. It differs in: (1) position of lateral head pore not immediately near the margin of head shield; (2) uniform thin setules in distal pecten on postabdominal claw. Even stronger differences are present between males of the two species (Kotov et al. 2009), but, unfortunately, males of  B. (S.) fatalis are unknown from Korea, while males of  B. longirostris were described by Yoon (2010). </p>
            <p> B. (S.) fatalis is common in the eastern half of China, Far East of Russia, Japan, Philippines, Cambodia and Thailand (Chiang &amp; Du 1979; Mizuno &amp; Takahashi 1991; Maiphae et al. 2008; Kotov et al. 2009; Tanaka &amp; Ohtaka 2010), and its presence in Korea was quite expected. This taxon is a Far Eastern endemic. </p>

            <p>Type locality. "Mouth of the Tom' River" (Smirnov &amp; Sheveleva 2010), Amur Area, Russia.</p>
            <p>Locality in Korea. 6a (see Fig. 1 and Table 1).</p>
            <p> Parthenogenetic female. In lateral view, body very high, “humped”, as Smirnov &amp; Sheveleva (2010) (Fig. 17 A). Body with strong lateral outgrowths in level of brood pouch (Fig. 17 B), in anterior view these “wings” rounded-triangle in adults (Fig. 17 C) and acute in juveniles (Fig. 17 K). Dorsal head pores typical for the genus (Fig. 17 D–E). Labral keel relatively small, with a rounded apex (Fig. 17 F). In anterior portion of valve there is an inner flap-like projection (Fig. 17 G); reticulation on valves as polygons with rounded angles and undulated edges. In posterior half of ventral margin, setae remarkable submarginally; in posterior portion of valves there are successive series of fine setules (Fig. 17 H–I). Postabdomen elongated, ventral margin concave, preanal margin concave, preanal angle strongly projected, anal margin concave, postanal margin straight, dorso-distal angle widely rounded, distal margin short, postabdominal claw located on a massive projection (Fig. 17 J). Postanal teeth thin, singular, present on postanal and anal margin; lateral setules longer in distal portion. Postabdominal claw with two basal spines, a strong distal basal spine (about 0.3 of claw length) and a short proximal spine (more than two times shorter than distal spine). Antenna I with 9 terminal aesthetascs. Antenna II as in  Chydorus sphaericus . Limbs were not studied. Size in our material 0.31–0.37 mm. </p>
            <p> Notes. We found only a single adult and a single juvenile female, not sufficient for a full redescription. Smirnov &amp; Sheveleva (2010) mentioned that in anterior view, the body is “triangular, with maximum width dorsally to the middle height”. We found that it is widened dorsally, forming lateral projections as  Disparalona ikarus or  Monospilus daedalus . Previously  C. irinae was known only from a single locality in the Amur basin. Now it is obvious that its range is wider. Unfortunately, it is impossible to associate any previous descriptions and illustrations from the Far East with this taxon due to a “tradition” to study specimens only in lateral view. This taxon seems to be an endemic of the Far East. </p>

            <p>Parthenogenetic female. Body moderately elongated for the genus, postero-dorsal angle distinct, lacking any denticles, posterior margin straight, postero-ventral angle widely rounded (Fig. 18 A, 19D). A lateral wing-like projection on each side of brood pouch (Fig. 18 B–C), in anterior view from rounded-triangular to acute (Fig 18 D–E). Sculpture of low longitudinal folds well-expressed in dorsal portion, visible as longitudinal lines in lateral view. Compound eye 2 times larger than ocellus. Dorsal head pores typical for the genus (Fig. 18 F). Labral keel relatively narrow, with widely rounded apex (Fig. 18 G). In posterior portion of ventral margin, setae located slightly submarginally, no setules between them; a row setules submarginally at posterior margin (Fig. 18 H). Postabdomen elongated in both adults in juveniles (Fig. 19 A, E), fluently narrowing distally, its length about 3.5 width. Preanal margin straight, preanal angle distinct, anal margin convex, postanal margin regularly curved to the base of postabdominal claw; dorso-distal angle and distal margin not expressed. About 7–8 long and thin singular postanal teeth, rows of setules on anal margin; setules in lateral series short. Postabdominal claw somewhat curved, as long as preanal margin, with a very short basal spine and an additional setule. Antenna I (Fig. 19 B) and II typical for genus. Limb I with ODL bearing a single seta, IDL with two long setae setulated distally and a short seta with pointed tip (Fig. 19 C). Size in our material 0.35–0.48 mm.</p>
            <p> Notes. This taxon was known from a single locality in the Amur basin. Now it is obvious that it is more widely distributed in the Far East, although the most common species there is  D. cf. hamata (Birge, 1879) (Fig. 20 A–D).  Disparalona ikarus differs from the latter in: (1) presence of lateral “wings”; (2) absent striae between reticulation lines; (3) weak dorso-distal angle and distal margin of postabdomen; (4) short basal spines on postabdominal claw; (5) absence of a strong hook-like seta on IDL. Although Kim &amp; Yoon (1987) and Yoon (2010) illustrated their "  Disparalona rostrata " only in lateral view, we can conclude that, most probably, they were dealing with  D. ikarus , keeping in mind differences between these two species in shape and armature of the postabdomen. </p>

            <p> Notes. A single female from Bak Sil Ji was undistinguishable from one earlier found in the Amur basin (Kotov et al. 2011b), most probably the northernmost limit of its distribution. Similar forms are present in China (Chiang &amp; Du 1979). Frey (1982b) regarded  E. barroisi as nomen  dubium , but Smirnov (1996) redescribed this species and concluded that it is widely distributed in the tropics of thr Old World. Both females from the Amur basin and Korea are similar with those described by Alonso (1987) as E. sp. from Iran, which is, most probably,  E. barroisi s.str. A recent attempt of redescription of the latter (Yalim &amp; Ciplak 2010) was not very successful, and the taxon needs to be re-investigated in more detail. This is the first record of the genus  Ephemeroporus Frey, 1982 for Korea. </p>

            <p>Parthenogenetic female. Body ovoid, elongated in lateral view (Fig. 21 A); strongly compressed laterally and having a well-expressed dorsal keel both on carapace and head. Dorsal margin without depression between valves and head shield, postero-dorsal angle broadly rounded, posterior margin convex, postero-ventral angles broadly rounded. Ventral margin slightly undulated. Rostrum acute, pointed downward (Fig. 21 B). Three connected main head pores, lateral pores minute. Labrum with a sub-triangular keel; its posterior margin without a denticle, with two groups of fine setules (Fig. 21 B–C). Row of ventral setae followed by a row of fine setules, in dorsal portion of posterior margin they are strong, denticle-like (Fig. 21 D–E). Postabdomen very long, narrowing distally, length about 5–6 height (Fig. 21 F). Preanal portion almost straight, preanal angle well-developed, anal margin almost straight, postanal angle not expressed, postanal margin straight to slifhtly concave; postanal portion 3–4 times longer than anal one. Postanal margin with about 20 clustered postanal denticles with fused bases (Fig. 21 G). Laterally series of fine setules. Postabdominal claw long, straight, with slightly curved tip; basal spine short, slightly bent, about 0.25 length of claw; few setules at the end of proximal pecten as strong spines (Fig. 21 G). Antenna I with length about 4–5 width, with three groups of fine setules at anterior face; among nine aesthetascs two longer than the rest, longest aesthetascs as long as antenna I; antennular seta thin, about 1/3 length of antenna I, protruding somewhat distally to middle (Fig. 21 B). Antenna II short, antennal formula: setae 0-0-3/0-1-3, spines 1- 0-1/0-0-1. Apical setae subequal in size, apical spines very short, spine on proximal exopod segment also very short (Fig. 21 H). Limb I with ODL bearing a long seta, armed with long setules; IDL with three setae, seta 1 large, well developed, about 1/3 length of ODL seta; setae 2 and 3 thick, curved, hook-like, with a short, setulated distal portion (Fig. 21 I). Size in our material 0.71–0.80 mm.</p>
            <p> Notes. Yoon (2010) recorded only  C. rectirostris Schödler, 1862 from Korea but as his illustrations lack denticles on postero-ventral angle of valve, this is not  rectirostris , but  C. vietnamensis Than, 1980 . We did not see the former in Korea, but found two other species:  C. uncinatus Smirnov, 1971 and  C. vietnamensis Than, 1980 . Earlier Kim (1988) misidentified  C. uncinatus from Korea as  C. rectirostris . </p>
            <p> According to Smirnov (1998),  C. uncinatus is distributed in southern Europe, Israel, Iraq, Egypt, Ethiopia, Rift Valley in Africa, South West Siberia, Central Yakutia and Central America. The American populations most probably belong to a separate species. In general,  C. uncinatus occupies the southern Palaearctic. It is recorded from the Amur basin (Kotov et al. 2011a), where  C. rectirostris and  C. fennicus Stenroos, 1898 s. lat. are also present. At the same time, its presence in tropical Vietnam, Cambodia and Thailand were put in doubt by Sinev (2011), see next section. </p>

Preanal portion straight, preanal angle well-developed, anal margin concave, postanal angle expressed, postanal margin straight; postanal portion 2.5 times longer than anal one. Postanal margin with 15–18 small triangular, postanal denticles, each distal one with a small additional denticle proximally to its base. Laterally, about 15 lateral series of fine setules. Postabdominal claw long, straight, with slightly curved tip; basal spine short, slightly bent, about 0.2 length of claw itself; setules at the end of proximal pecten as strong spines (Fig. 22 F). Antenna I with length about 4–5 width, with three groups of fine setules at anterior face; among nine aesthetascs two longer than the rest, longest aesthetascs as long as antenna I; antennular seta thin, about 1/3-1/ 4 length of antenna I, protruding somewhat distally to middle (Fig. 22 B). Antenna II short, antennal formula: setae 0-0-3/0-1-3, spines 1-0-1/0-0-1. Apical setae subequal in size, apical spines very short, spine on proximal exopod segment also very short (Fig. 22 G). Limb I with ODL bearing a long seta, armed with long setules; IDL with four clusters of setules and three setae; seta 1 large, well developed, about 1/3 length of ODL seta; setae 2 and 3 thick, curved, hook-like, with a setulated distal portion (Fig. 22 H). Size in our material 0.39–0.50 mm.</p>
            <p> Notes.  Camptocercus vietnamensis differs from  C. uncinatus in: (1) a smaller size (Sinev 2011), although such comparison should be based on ample samples; (2) higher body; (3) presence of a denticle on labral keel; (4) postanal teeth consisting of a strong denticle and one small additional denticle proximally to its base. Until recently it was known only from Vietnam, but Sinev (2011) proposed that some tropical populations earlier identified as C. </p>
            <p> uncinatus could also belong to  C. vietnamensis . It is a rheophylic species (Sinev 2011), but we found it in an oxbow lake. After our finding, it is clear that it is widely distributed in Pacific Asia. We regard it as a tropical-subtropical species that deeply penetrating the Palaearctic. Korea may be the northernmost area of its distribution, because it is apparently absent from the Amur basin (Kotov et al. 2011a). </p>

It also occurs in some other tropical and subtropical countries, i.e., Israel (Bromley 1993), Chad (Rey &amp; Saint-Jean 1968), Sudan (Green 1984), Mexico (Van de Velde et al. 1978) and Cambodia (Tanaka &amp; Ohtaka 2010), making it a tropical-subtropical taxon. We found it far north from the tropics, and Korea is, most probably, the northernmost area of its distribution.  Kurzia longirostris is definitively absent in Far East of Russia, while  K. cf. latissima is common in the area of Lake Khanka (Kotov, unpublished) and is also known for China (Chiang &amp; Du 1979). This is the first record of the genus  Kurzia for Korea. </p>

            <p>Parthenogenetic female. Body triangular-ovoid, dorsal margin slightly and uniformly curved from tip of rostrum to smooth postero-dorsal angle; posterior margin convex (Fig. 24 A). Coarse striation non-distinct, fine striation very distinct, see Kotov 2009. Head small, compound eye small, ocellus slightly larger (Fig. 24 B). Three large head pores on area devoid of reticulation. Labral keel widely-triangular-ovoid, with distinct apex, its anterior margin with fringe of long setules, 4–5 lateral groups of fine setules. In anterior portion of the ventral margin setae longer (Fig. 24 C). On posterior margin, a row of setules on inner side of valve, located far from margin, they are larger that 'setules' of marginal membrane (see Kotov 2009). Postabdomen broad, subovoid, robust, preanal margin shorter than anus, with 3 relatively large projections in basal 2/3, preanal and postanal angles well defined, no distal margin and no dorso-distal angle (fig. 24D). Postanal marginal denticles in numerous clusters, size increasing distally in each cluster, 10–12 fascicles of stout lateral setae, decreasing in size basally, 3–4 setae in each fascicle on distal portion, only 2 setae in each fascicle in middle. Postabdominal claw slightly shorter than preanal plus anal portion of postabdomen, slightly curved, basal spine rudimentary or absent (Fig. 24 E). Antenna I not reaching tip of rostrum, with 4 transverse rows of setules at anterior face and series of short setules at tip. Sensory seta arising about 1/4 of way from tip. Largest aesthetasc less than half length of appendage. Antenna II with few stout spinelike setules on first and second endopod segments; a strong spine on proximal segment of exopod longer that the next segment (Fig. 24 F). Distal lateral seta short, basal lateral seta as long as apical seta. Limbs as described by Kotov (2009). Size in our material 0.6 mm.</p>
            <p> Notes.  Leydigia acanthocercoides differs from  L. ciliata Gauthier, 1939 in (1) relatively wide postabdomen and (2) predominantly doubled, not tripled, lateral setae of the middle portion of postanal margin. The latter is a tropical-subtropical species (Kotov et al. 2003) also present in Korean Peninsula and well illustrated by Yoon &amp; Kim (1993) and Yoon (2010). The status of Asian "  L. ciliata " needs to be checked, because Sinev &amp; Sanoamuang (2011) revealed some differences in male morphology between Asian and African populations. </p>
            <p> About  L. acanthacercoides Kotov (2009) mentioned that “At present I can confirm the presence of this species only in Europe and northern Asian Russia ('Siberia')”. The  acanthocercoides -group needs to be revised. Recently Kotov &amp; Alonso (2010) demonstrated that in the Iberian Peninsula there are two species earlier identified as “  L. acanthocercoides ” (i.e. in Alonso, 1996). Our superficial examination of a single Korean population did not reveal any differences from the European populations. So, Korea might be the most southern limit of L. acanthocercoides’ distribution. Among specimens illustrated from China under different names  L. acanthocercoides was not found, but  L. ciliata is present (Chiang &amp; Du 1979, Fig. 139–140, 142). </p>

            <p>Parthenogenetic female. Body rounded, very high, moulting incomplete (Fig. 25 A). As dorsally, body relatively compressed laterally, with lateral projections in anterior half of the valves of first instar (Fig. 25 B). Sculpture with numerous shallow depressions, more expressed in dorsal portion. Rostrum short, compound eye absent, ocellus large. Head shield with step-like incisions on each side in antero-lateral portion, rostrum wide, with four tubercles; single, relatively small major head pore in posterion portion, lateral pores absent (Fig. 25 C). Setae on ventral margin of valve short, unilaterally setulated (Fig. 25 D–E). Postabdomen short, its length 2–2.5 of width. Preanal margin straight; preanal angle distinct, obtuse; anal margin concave, postanal angle obtuse, massive; postanal margin almost straight, almost no projection for postabdominal claw (Fig. 25 F). On postanal and anal margin, 3–6 strong, single postanal teeth, groups on smaller teeth on anal margin. Laterally, several row of spinules. Postabominal claw massive, with two pectens, in proximal pecten distalmost denticle shorther than the second one. Basal spine long, 3–4 thin setules at its base (Fig. 25 F–G). Antenna I short, its length 2.5 times of width; antennular sensory seta located somewhat distally to middle, its length subequal to antenna I length; 8 terminal and single lateral easthetascs (Fig. 25 H–I). Antenna II short, with two sensory setae at coxal portion; basal segment with a short spine distally (Fig. 25 J). Antennal formula: setae 0-0-3/0-1-3, spines 1-0-1/0-0-1. Spine on proximal segment of exopod very long, more that 1.5 times longer than next segment; spines on apical segments about 1.5 times longer than these segments. Six pairs of limbs as it was described by Kotov &amp; Sinev (2011), ODL with a single seta armed with short setules distally; IDL with two setae of subequal size and a third rudimentary seta. (Fig. 25 K). Size in our material 0.34 mm.</p>
            <p> Notes. The species, known from a single locality in the Amur basin (Kotov &amp; Sinev 2011), clearly has a wider range. Illustrations and descriptions of the Chinese and Japanese populations (Chiang &amp; Du 1979; Mizuno &amp; Takahashi 1991) are not detailed enough for evaluating their species status. After the description of  M. daedalus , all previous identifications of  M. dispar Sars, 1862 from the Far East, including Korea (Yoon &amp; Kim 1987; Yoon 2010), need to be re-checked. </p>
