WoRMS (WoRMS Editorial Board, 2023) has recognized 91 species as valid in the genus Asterocheres. We accept 88 of those 91 species as valid, except the following three species: A. berniciensis (Brady, 1899); A. carausi Marcus &amp; Por, 1960; and A. ornatus (Brady &amp; Robertson, 1876). Asterocheres berniciensis was described under the name of Cyclopicera berniciensis based on the male. The description and illustration of A. berniciensis exhibit no diagnostic feature of Asterocheres and we recognize it here as a species inquirenda. We follow Stock (1969) who treated A. carausi to be a synonym of A. uncinatus (Krichagin, 1873). Asterocheres ornatus (originally as Ascomyzon ornatum) is currently recognized as a species of the genus Acontiophorus Brady, 1880 (Brady, 1880; Giesbrecht, 1899). WoRMS has recognized A. siphonatus Giesbrecht, 1897 as a synonym of Dermatomyzon nigripes (Brady &amp; Robertson, 1876), but we treat it a distinct species of Asterocheres, as redescribed by Conradi &amp; Bandera (2011) and in the present paper.

In leg 3, third endopodal segment (Fig. 3F) bearing slightly curved outer distal process.</p> <p>Exopodal segment of leg 5 (Fig. 3G) nearly rectangular, 2.56 times longer than wide (34 × 13.3 μm), with few spinules on inner and outer margins; 3 setae 42, 36, and 18 μm long, respectively, from outer to inner. Leg 6 (Fig. 3H) represented by outer distal part of genital operculum bearing 2 unequal setae, spinules on outer and inner margin, and 4 or 5 setules on inner margin.</p> <p>Remarks. This is the first known species of Asterocheres in Korea (Kim, 1998). The newly examined material collected in Korea are identifiable as this species by the characteristic, sexually dimorphic features revealed on the third endopodal segment of male leg 2 and by the characteristic ornamentation on the genital operculum of the male, which Ho (1984) described and figured in the original description. Ho (1984) overlooked the presence of an aesthetasc on the thirteenth segment of the male antennule and a slight sexual dimorphism on leg 3, which are considered as useful characters in the present paper.</p> </div>	https://treatment.plazi.org/id/ED1887CBFFFBFFE1FCF8B33FB0C16328	Public Domain	No known copyright restrictions apply.

Asterocheres siphonatus Giesbrecht, 1897 has been known from European waters. It was redescribed by Sars (1915) under the name of Ascomyzon lilljeborgi Thorell, 1859 (a name preoccupied by Asterocheres lilljeborgi Boeck, 1859) and by Bandera &amp; Conradi (2011) under the name Asterocheres siphonatus. This species exhibits several features unusual for the genus, such as the elongated oral siphon which extends over leg 4 and bears numerous horizontal striations, the thin mandibular stylet which is much longer than the palp, the two almost equally long distal setae on the mandibular palp, one of the setae on the inner lobe of the maxillule is much longer than other three setae on the same lobe, one of the setae on the outer lobe of the maxillule is markedly shorter than other three setae, and the rostrum is well-developed with a rounded distal apex. These features were described or illustrated by Sars (1915) and Bandera &amp; Conradi (2011), and Korean material reveals the same features, as well. Some discrepancies between the two geographical forms are noticed, as follows: (1) the body length of the female is 1.24 mm in Korean material, compared to 880-960 μm in the measurement of Bandera &amp; Conradi (2011) for European material; (2) the outer seta on the basis of legs 1 and 2 of Korean material is smaller than those illustrated by Sars (1915) and Bandera &amp; Conradi (2011); (3) the inner coxal seta of leg 1 of Korean material is larger than that illustrated by the European researchers. However, these discrepancies are thought to be minor and zoogeographical variations.</p> <p>Asterocheres siphonatus is recorded here as a circumpolar species. Kim (2016) already reported A. lilljeborgi Boeck, 1859 and A. simulans (Scott T., 1898) from Korean waters as other examples of Asterocheres species with the circumpolar distribution.</p> </div>	https://treatment.plazi.org/id/ED1887CBFFF4FFE6FF7FB3DCB1C76770	Public Domain	No known copyright restrictions apply.

A comparison of characters between the new species and its congeners reveals that the new species appears to be most close to A. boeckii (Brady, 1880) which was redescribed by Bandera &amp; Conradi (2016). The male is unknown in A. boeckii. Based on female characters 1-14 in Table 1, the two species exhibit 86% similarity value, sharing 12 identical character states in 14 characters. As revealed two differences, the genital double-somite of the female is shorter than wide in A. boeckii but slightly longer than wide in A. geminus n. sp., and the oral siphon extends to the insertions of leg 1 in A. boeckii but to the midway between the maxilliped and leg 1 in A. geminus n. sp. As additional differences, the new species has (1) a tubercle-like process on the distal segment of the maxilla (vs. the tubercles absent in A. boeckii according to the figure of Bandera &amp; Conradi, 2016), (2) the mandibular palp (including the longer distal seta) which is as long as the coxal stylet (vs. the palp is shorter than the stylet in A. boeckii), and (3) the setules on the postgenital lateral margins of the genital double-somite are subequal in the shape and length (vs. the setules of A. boeckii are grouped into longer anterior and shorter posterior groups, as illustrated by Bandera &amp; Conradi, 2016).</p> <p>It is noticed that the third endopodal segment of male leg 3 of the new species exhibits the same sexual dimorphism as in A. aesthetes and leg 6 of the male is also very similar between the two species. However, unlike A. aesthetes, the new species bears no sexual dimorphism in leg 2 and shows other minor differences in the mandible, maxilla, and leg 5.</p> </div>	https://treatment.plazi.org/id/ED1887CBFFF3FFFAFF41B777B1B3655F	Public Domain	No known copyright restrictions apply.

Asterocheres processus n. sp. may be differentiated from its congeners by two diagnostic features revealed in leg 1. Firstly, the coxa lacks an inner seta. Secondly, the third endopodal segment bears a prolonged outer distal process. The first feature is shared with five species in the genus: A. pilosus Kim, 2004; A. eugenioi Bandera &amp; Conradi, 2014; A. sarsi Bandera &amp; Conradi, 2009; A. trisetatus Kim, 2010; and A. banderae Kim &amp; Lee, 2023. The second feature is shared with four species (A. crinoidicola Humes, 2000; A. mucronipes Stock, 1960; A. pilosus; and A. unioviger Kim, 2010). Of the latter four species, A. mucronipes has been removed to the genus Stockmyzon Bandera &amp; Huys, 2008 by these authors (Bandera &amp; Huys, 2008). Thus, A. processus n. sp. is comparable only with A. pilosus as only these two species have both the diagnostic features. Asterocheres pilosus is associated with the echinoid Eucidaris thouarsii (L. Agassiz &amp; Desor, 1846) on the Pacific coast of Panama (Kim, 2004a). In the latter species, the female antennule is 19-segmented, the mandibular palp is 2-segmented, the oral siphon extends to the insertions of the maxillipeds, the distal setae on the inner lobe of the maxillule are shorter than the distal seta of the outer lobe and one of the setae on the outer lobe is specialized with long setules, and the fourth leg has an inner coxal seta. These features of A. pilosus are not adjustable to A. processus n. sp.</p></div> 	https://treatment.plazi.org/id/ED1887CBFFEFFFFFFF41B508B4B260D5	Public Domain	No known copyright restrictions apply.

Leg 6 (Fig. 13B) represented by 2 naked setae on genital operculum.</p> <p>Remarks. The comparison of A. culicis n. sp. with its congeners on the basis of the characters listed in Table 2 reveals that five species (A. ellisi Hamond, 1968; A. parvus Giesbrecht, 1897; A. peniculatus Kim, 2010; A. suberitis Giesbrecht, 1897; and A. urabensis Kim, 2004) show closeness to the new species, with similarity values more than 75%. These five species are distinguished from the new species by their different features, as follows: A. ellisi has a shorter terminal claw of the antenna, which is shorter than the first endopodal segment, a longer oral siphon which extends beyond leg 1, and no sexual dimorphism in the swimming legs (Bandera &amp; Mercedes, 2009). Asterocheres peniculatus has shorter caudal rami which are wider than long, a short terminal claw of the antenna, which is shorter than the first endopodal segment, and a rudimentary outer distal seta on the third endopodal segment of male leg 3. Asterocheres suberitis has a shorter oral siphon which reaches the insertions of the maxilliped, a longer mandibular palp which is longer than the stylet, and a 17-segmented male antennule (Giesbrecht, 1899). Asterocheres urabensis has shorter caudal rami which are 1.20 times longer than wide, about 15 setules on the postgenital lateral margin of the female genital double-somite, as illustrated in the original description, and an elongated exopodal segment of female leg 5, which is 3.65 times longer than wide (Kim, 2004a).</p> <p>Asterocheres parvus was very briefly recorded by Giesbrecht (1899) with figures about the body form and urosome of the female. Giesbrecht (1899) recorded the body length of the female as 0.55 mm long and illustrat- ed the body having pointed posterolateral corners of the first three prosomal somites and the genital apertures positioned at the anterior third of the genital double-somite. In contrast, in A. culicis n. sp. the body of the female is larger, 727 μm long in dissected specimen, all the prosomal somites have rounded posterolateral corners, and the genital apertures are positioned at the midway of the genital double-somite.</p> </div>	https://treatment.plazi.org/id/ED1887CBFFEAFFF3FC96B092B49E65DE	Public Domain	No known copyright restrictions apply.

Leg 6 (Fig. 15G) represented by 2 small, unequal setae and 1 small denticle on genital operculum.</p> <p>Male. Unknown.</p> <p>Remarks. As a combination of diagnostic features of A. eurychelatus n. sp. (1) the caudal ramus is short, not longer than wide; (2) the antennule of the female is 20-segmented; (3) the mandibular palp is 1-segmented; and (4) leg 4 lacks an inner seta on the coxa. The new species shares this combination of the diagnostic features with six congeners: A. siphonatus; A. proboscideus Stock, 1966; A. stocki Nair &amp; Pillai, 1984; A. banderaae; A. processus n. sp.; and A. bulbosus Malt, 1991. The first three species are easily separated from the new species by their unusually long oral siphon, which extends beyond leg 4 in A. siphonatus as in the redescription in the present paper, over the caudal rami in A. proboscideus (see Stock, 1966), and to leg 5 in A. stocki (see Nair &amp; Pillai, 1984). Asterocheres banderaae and A. processus differ from the new species in lacking an inner coxal seta on leg 1. Asterocheres bulbosus also differs from the new species in having only one seta on the first segment of the antennule as described and illustrated by Malt (1991), which was confirmed by Bandera &amp; Conradi (2009b) (vs. two setae in the new species).</p> <p>At least one of the above four diagnostic features is unknown in A. corneliae Schirl, 1973; A. dentatus Giesbrecht, 1987; and A. minor Thompson &amp; A. Scott, 1903. As important differences of these species from the new species, the oral siphon of A. corneliae is much thinner than that of the new species and reaches leg 1 (Schirl, 1973), the prosome of A. minor is circular and its abdominal somites are longer than wide as illustrated by Thompson &amp; Scott (1903), and the genital double-somite of the female of A. dentatus bears a pointed process on the lateral margins (Giesbrecht, 1899).</p> <p>The form of the terminal claw of the antenna and maxilliped of A. eurychelatus n. sp. is remarkable, since it is unusually broadened, a very rare feature within the genus.</p> </div>	https://treatment.plazi.org/id/ED1887CBFFE7FFF0FF41B35FB34065D9	Public Domain	No known copyright restrictions apply.

Five species of Asterocheres are selected for a comparison with A. spiniventer n. sp., as the new species exhibits higher similarity values with these species (more than 75% values) than with other species (Table 2). These five species are A. canui Giesbrecht, 1897; A. suberitis; A. uncinatus; A. faroensis Crescenti, Baviera &amp; Zaccone, 2010; and A. intermedius (Hansen, 1923). However, they are clearly distinguished from the new species by their diagnostic features exhibited in the mandibular palp and oral siphon, since the first three species have a 2-segmented mandibular palp (vs. 1-segmented in A. spiniventer n. sp.) and the remaining two species, A. faroensis and A. intermedius, have a longer oral siphon that approaches over the insertion of the maxilliped in the former species (Crescenti et al., 2010) or over leg 1 in the latter species (Hansen, 1923) (vs. the oral siphon approaches to the insertion of the maxilliped in A. spiniventer n. sp.).</p> <p>As key characters of A. spiniventer n. sp., the caudal ramus is 1.5 times longer than wide, two distal setae on the mandibular palp are extremely unequal in length (longer seta six times longer than shorter one), and the genital double-somite of the female is ornamented with about 25 spinules arranged along the entire postgenital lateral margin. Most of all, the nature of the sexually dimorphic morphological transformation of the endopod of male leg 1 is unique to the new species.</p> </div>	https://treatment.plazi.org/id/ED1887CBFFE0FFC8FF7FB537B2646154	Public Domain	No known copyright restrictions apply.

Nine species of Asterocheres are selected as relatives of A. tridentatus n. sp. after comparing the new species with its congeners based on the character states of 17 characters (Table 2). These nine species are A. alter Eiselt, 1965; A. canui; A. cubensis Varela, 2010; A. fernadezmilerai Varela, 2010; A. halichondriae Stock, 1966; A. manaarensis Thompson &amp; A. Scott, 1903; A. proboscideus; A. tenuipes Kim, 2010; and A. tetrasetosus Johnsson, 1999 and distinguished from the new species by their different features. The oral siphon extends before the maxilliped in A. alter, to the maxilliped in A. canui, A. halichondriae, and A. tetrasetosus, to leg 1 in A. tenuipes, and over leg 1 in A. proboscideus (vs. the oral siphon extends between the maxilliped and leg 1 in A. tridentatus n. sp.). Therefore, these six species are distinguished from the new species by having different lengths of the oral siphon. Asterocheres cubensis and A. fernandezmilerai both described from the West Indies (Varela, 2010a) have 19-segmented female antennule (vs. 20-segmented in A. tridentatus n. sp.) and an inner coxal seta on leg 4 (vs. the seta is absent in A. tridentatus n. sp.). Therefore, the latter two species are also distinguished from the new species.</p> </div>	https://treatment.plazi.org/id/ED1887CBFFD5FFC4FF41B455B4B861D7	Public Domain	No known copyright restrictions apply.

Asterocheres horridus has a longer oral siphon which extends to leg 1, a 2-segmented mandibular palp, and the exopodal segment of female leg 5 which is 2.90 times longer than wide (Kim, 2016).</p> <p>The distinctiveness of the above three species and A. nodulosus n. sp. can be confirmed by their different forms of legs 2 and 3 of the male, as follows: (1) in the third endopod of male leg 2, the outer distal process is expanded with a small tubercle in A. aesthetes, thinned in A. horridus, and slightly curved in A. fici n. sp. and A. nodulosus n. sp.; (2) in the third endopodal segment of male leg 3, the outer distal process is slightly curved in A. aesthetes, A. fici n. sp., and A. nodulosus n. sp., but not modified in A. horridus; (3) the outer distal seta of the third endopodal segment of male leg 3 is minimized in A. fici n. sp. and A. nodulosus n. sp. but normal in A. aesthetes and A. horridus; and finally, the presence of a nodule-like proximal expansion on the inner distal seta of the third endopodal segment of male leg 2 is a unique feature of A. nodulosus n. sp., which is easily observable under the microscope without dissection.</p> </div>	https://treatment.plazi.org/id/ED1887CBFFD1FFDFFCF8B191B254638A	Public Domain	No known copyright restrictions apply.

It is noticed that the latter five species have in common a 20-segmented female antennule bearing an aesthetasc on the 18th segment and a 1-segmented mandibular palp which is longer than the stylet. However, these five congeners differ from A. tetraodontis n. sp. in having the following different features in the female:</p> <p>In A. indivisus, the caudal rami and genital double-somite are distinctly wider than long (vs. as long as wide in A. tetraodontis n. sp.), and the exopodal segment of leg 5 is fusiform (vs. rectangular in A. tetraodontis n. sp.) and its outer and middle distal setae are characteristically long, more than twice longer than the segment (vs. the setae are not so long in A. tetraodontis n. sp.). In A. planus, the caudal ramus is distinctly longer than wide, the mid-terminal seta on the exopod of leg 5 is longer than the other two setae, the cephalothorax is broadened, and the distal segment of the maxilla is stout and strongly curved. In A. spinosus, the caudal ramus is 1.88 times longer than wide, the postgenital lateral margin of the genital double-somite is ornamented with numerous setules, and the oral siphon extends over the maxilliped (Kim &amp; Min, 2013). In A. eurychelatus n. sp., the genital double-somite is distinctly longer than wide, the terminal claw of the antenna and maxilliped is broadened, and the exopodal segment of leg 5 is fusiform, with three subequal naked setae. In A. scutellatus n. sp., the genital double-somite is distinctly longer than wide, the mandibular stylet bears six teeth distally (vs. four teeth in A. tetraodontis n. sp.), the exopodal segment of leg 5 is slightly fusiform and its distal setae are all naked and shorter than the exopodal segment (vs. the exopodal segment is rectangular and two of distal setae pinnate and the mid-terminal one is longer than the segment in A. tetraodontis n. sp.).</p> </div>	https://treatment.plazi.org/id/ED1887CBFFCAFFDCFF7FB07DB15067F3	Public Domain	No known copyright restrictions apply.

Asterocheres dokdoicus n. sp. appears closely related to A. hoi which was described by Bandera &amp; Conradi (2013) on the basis of females collected at Curaçao in the Caribbean Sea. The new species and A. hoi share all character states in 13 characters (Table 2), thus they cannot be distinguished from each other based on those character states. Differences between the two species are detectable in minor details. According to the original description and illustration of A. hoi, in the female of this Caribbean species, (1) the first segment (syncoxa) of the maxilla is slightly expanded proximally (cf. not expanded in A. dokdoicus n. sp.), (2) the second segment (basis) of the maxilliped bears row of spinules along the inner margin (cf. the margin is smooth in the new species), (3) the inner coxal seta of leg 1 is naked (cf. pinnate in the new species), (4) the outer seta on the basis of legs 1-4 is naked (cf. the outer seta on the basis of leg 1 is also naked but those of legs 2 and 3 are pinnate in the new species), and (5) the exopodal segment of leg 5 is almost three times longer than wide (cf. the segment is 2.47 times longer than wide in the new species).</p> <p>The male of A. dokdoicus n. sp. has characteristically modified endopods of legs 2 and 3, which are readily observable under the microscope without dissection. Since A. hoi is known only by the female, it is expected that the male of the latter species will be discovered in the future and confirm the distinctiveness of both species.</p> </div>	https://treatment.plazi.org/id/ED1887CBFFC9FFD0FF41B7F5B52D60B5	Public Domain	No known copyright restrictions apply.

Armature formula for legs 1-4 as follows:</p> <p>Coxa Basis Exopod Endopod</p> <p>Leg 1 0-0 1-1 I-1; I-1; III, 2, 2 0-1; 0-2; 1, 2, 3 Leg 2 0-1 1-0 I-1; I-1; III, I, 4 0-1; 0-2; 1, 2, 3 Leg 3 0-1 1-0 I-1; I-1; III, I, 4 0-1; 0-2; 1, 1 +I, 3 Leg 4 0-1 1-0 I-1; I-1; III, I, 4 0-1; 0-2; 1, 1 +I, 2</p> <p>Leg 5 (Fig. 39E) consisting of dorsolateral seta on fifth pedigerous somite and free exopod; exopodal segment sub-fusiform, 2.03 times longer than wide (63 × 3 μm), armed with 3 pinnate setae distally; lengths of distal setae 26, 27, and 45 μm, respectively, from outer to inner; innermost seta longest. Leg 6 (Fig. 39F) represented by 1 pinnate seta and 1 small spinule on genital operculum.</p> <p>Male. Unknown.</p> <p>Remarks. Asterocheres exilis n. sp. belongs to a group of Asterocheres characterized by the loss of the inner coxal seta on leg 1. This group comprises four known species: A. banderaae, A. eugenioi, A. sarsi, and A. trisetatus (Bandera &amp; Conradi, 2014; 2016; Kim &amp; Lee, 2023). However, A. exilis n. sp. is readily differentiated from the four congeners by having (1) a narrow body (vs. the body is broad or moderately broad in the four congeners), (2) a genital double-somite which is distinctly longer than wide (vs. wider than long in the four congeners), and (3) 19-segmented female antennule (vs. 20- or 21-segmented in the four congeners). As additional diagnostic features of A. exilis n. sp., the outer lobe of the maxillule is armed with three setae only, and all the setae on the exopod of leg 5 are pinnate and its innermost seta is longer than the other two setae.</p> </div>	https://treatment.plazi.org/id/ED1887CBFFC5FFD5FCF8B0B3B38163EB	Public Domain	No known copyright restrictions apply.

Leg 6 (Fig. 42B) represented by 2 small setae on posterolateral corner of genital somite.</p> <p>Remarks. In Asterocheres, the inner coxal seta is often absent in leg 4. However, the absence of the same seta in leg 3 has not been reported in this genus, thus the latter feature of A. zodius n. sp. is unique within the genus, which allows to differentiate the new species from all its congeners. As additional diagnostic features of the new species, the genital double-somite of the female and the genital somite of the male are quadrangular, and the caudal setae are short and naked. These features may clearly characterize the new species.</p> </div>	https://treatment.plazi.org/id/ED1887CBFFC0FFA9FC96B39CB1EE6713	Public Domain	No known copyright restrictions apply.
