03C487E1FFD3DD2AAB9DF84549B5FD5F.taxon	discussion	Comments. A species of the C. cornuta - complex (Berner 1985), recently found to be a hornless form of C. cornuta (D. B. Berner, personal communication), but specimens from different continents should be reconciled. Richard published two papers describing this species in 1894, but the article describing Mediterranean populations (Richard 1894 a) referred to previous publication on Vietnam (Richard 1894 c). Therefore the Vietnam locality should be considered the type locality of this species. The status of Mediterranean populations of C. cf. rigaudi mentioned by Richard (1894 a) himself and by subsequent European authors (Alonso 1996), as well of populations from other regions of the world (Berner 1985), should be compared.	en	Kotov, Alexey A., Ferrari, Frank D.

03C487E1FFD2DD2AAB9DFB7D4AEEFA54.taxon	discussion	Comments. According to Orlova-Bienkowskaja (1998), S. iheringi is a junior symonym of S. daphnoides. However, a preliminary molecular-phylogenetic investigation (D. J. Taylor, personal communication) suggests an independent status for the South American populations, so S. iheringi is the name that should be applied only to the South American populations.	en	Kotov, Alexey A., Ferrari, Frank D.

03C487E1FFD5DD2FAB9DF8AD4C17FAA9.taxon	description	Redescription. Parthenogenetic female. Body moderately compressed laterally in anterior view, relatively short and wide in lateral view, dorsal margin regularly curved from distalmost extremity to posterodorsal angle, posterior margin straight, its height more than half of body height, ventral margin almost straight, with a shallow depression anterior to mucro (Fig. 3 A). Head without an ocular dome (Fig. 3 B). Frontal head pore small, located far from ventral margin of head shield (as seen from anterior side) at level of antennular sensory setae (Fig. 3 C – E). Fornices well-developed, covering coxal part of antenna II. Lateral head pore small, ovoid, located near ventral margin of head shield (Fig. 3 F – G). Compound eye small, ocellus absent. 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 (Fig. 3 H). “ Seta kurzi ” located on internal side of valve anterior to abovementioned depression near mucro, mucro strong and long with truncated tip supplied with a system of minute indentations, and 1 – 3 incisions on ventral side (Fig. 3 I), incisions absent from rare specimens with shortened mucro (Fig. 3 J). Series of minute setules at inner side of valve near posterior valve margin. Thorax relatively long, with 6 limb pairs. Postabdomen strongly compressed laterally, with width approximately equal along all its length, with ventral (although functionally dorsal) margin almost straight (Fig. 3 K). Preanal margin long, slightly concave, with groups of setules distally. Sides of postabdomen supplied with series of finer setules. 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 spinules, while proximal pecten consists of 6 – 8 rather strong and thin teeth (Fig. 3 L – M). Postabdominal seta somewhat shorter than preanal margin, its distal section about 1.5 times shorter than distal one. Antenna I fused with rostrum, rather long, its length from tip to tip of rostrum about 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 post-aesthetasc portion (Kotov et al. 2009), regularly bent in this taxon. Pre-aesthetasc portion straight, regularly narrowing distad in anterior view, an internal spine near a flat site of origin of aesthetascs. Post-aesthetasc portion directed ventrally and posteriorly, remarkably curved in lateral view. Both portions supplied with dorsoventral series of fine denticles. Antenna II typical for the genus, six pairs of thoracic limbs with morphology indistinguishable from that in other species (Kotov 1996, 1997 a). Ephippial female, male.

Basal endite with 4 anterior setae of subequal size (4 – 7), armed with small setules distally, a small bottle-shaped sensillum near seta 4. On posterior surface, 6 setae (a – f) of similar size, bilaterally armed with sparse, fine setules. Gnathobase separated from basal endite. Distal armature of gnathobase with large, bottle-shaped sensillum (1), 3 setae (2 – 4), plus setules. Filter plate III with 8 setae of similar size. Trunk limb IV (Fig. 6 G – H). Exopodite wide, subovoid, with 7 setae of unequal size (1 – 7). Inner-distal portion of limb IV with 4 marginal setae (1 – 4), distal seta with minute setules on distal section, setae 2 – 4 each with thick basal section and slender, setulated distal section, sensillae located near setae 2 and 3. On posterior surface, 4 soft setae (a – d). Gnathobase distinct with 4 distal setae. Filter plate with 6 setae. Trunk limb V (Fig. 6 I): Exopodite large, subovoid, with a single distal seta 1 and 3 lateral setae (2 – 4), distal to seta 1 are 2 small projections bearing long setules. Inner limb portion as elongate, flat lobe, with setulated margins, setae 1 and 2 setulate. Distal armature of gnathobase as a single projection, filter plate V with 4 long setae. Ephippial female, Male. See Gurney (1909, 1928). The descriptions do not correspond with contemporary level of detail, although the illustrations of the habitus of male and ephippial female (Gurney 1909, figs. 20, 23) are quite reliable. Size. Parthenogenetic females 0.33 – 0.57 mm (in Richard’s specimens), male 0.35 mm (Smirnov 1996).	en	Kotov, Alexey A., Ferrari, Frank D.

03C487E1FFCBDD34AB9DFBA74C91F854.taxon	diagnosis	Differential diagnosis. Among species of the Pleuroxus with deep body (see Frey 1991; Smirnov 1996; Kotov 2008), P. letournexi is remarkable in its (1) very small size, (2) sub-globular shape, (3) absence on any keel or ridge on dorsal portion of brood chamber and (4) presence of successive series of short, thin postanal teeth as in some other non-globular aduncus - like species (see Frey 1993 a; Alonso 1996; Smirnov et al. 2006) and instead of strong singular teeth as in the majority of other sub-globular species. P. letournexi, without a basal peg on antenna I, is another aduncus - like species compromising Frey’s (1993 b) intergeneric subdivision of Pleuroxus, as was proposed earlier by Kotov (2008); the size of this peg differs even in some of the closest congeners (Kotov & Sheveleva 2008). The absence of a basal peg on antenna I in P. letournexi, as well as in few other species (Smirnov et al. 2006), differentiates these species from the remaining aduncus - like species. P. letournexi has a typical set of filter setae on the gnathobase of limbs II – V (8 - 8 - 6 - 4), which differentiates it from other Pleuroxus - like genera and from a few species of the Pleuroxus (see Frey 1991, 1993 a – b; Kotov 2008).	en	Kotov, Alexey A., Ferrari, Frank D.

Frey (1982) considered the name a nomen dubium, based primarily on the absence of Richard's types, but Smirnov (1996) correctly noted that the species can be distinguished based on Richard's figures and descriptions. The name has been applied to populations found around the world (Smirnov 1996); in Asia they are found even in the Amur Basin (Kotov, unpublished). Ephemeroporus sp. described by Alonso (1987) may be this species. The non-Mediterranean populations remain to be reconciled with the Mediterranean populations.	en	Kotov, Alexey A., Ferrari, Frank D.
