So far, 13 species of Crossodonthina were reported from the C. nipponica species group (Jiang &amp; Wang 2024), making C. jiuyishanensis sp. nov. the fourteenth one of this group. Comparing C. jiuyishanensis sp. nov. to other species of this group, C. jiuyishanensis sp. nov. is most similar to C. acuminata Jiang &amp; Wang, 2021 from China (Hunan Province) in: head chaetotaxy (tubercle Oc with 3 chaetae, tubercle Fr with 3 chaetae, cephalic tubercles Di and De with 2 chaetae each); Three chaetae on tubercles Di of Abd. I–III each; and the presence of a chaetae s on tubercles L of Abd. I–III. However, C. jiuyishanensis sp. nov. differs from C. acuminata Jiang &amp; Wang, 2021 by the following characters: chaetotaxy on Th. I (with 1, 2, 2 chaetae on tubercles Di, De, Dl, respectively, in the new species, versus usually 1, 3, 2 in the latter one); number of chaetae on tubercle So of head (6 chaetae on tubercle So of head in C. jiuyishanensis sp. nov., versus 8 in C. acuminata); number of chaetae on tubercle L of Abd. V (7 or 8 chaetae in the new species versus 3 or 4 in the latter species); number of chaetae on Fu (3 chaetae in the new species versus no chaeta in C. acuminata); number of basal mandible teeth (2 in the new species versus 3 in the latter one); and teethed branches on mandible (2 in the new species (the third branch and the sixth branch, Fig. 5) versus no teethed branch in C. acuminata); number of chaetae s on dorsum of Ant. IV (6 in the new species versus 8 in the latter species).</p><p>C. jiuyishanensis sp. nov. is also close to C. laterisensillata Ohira, Kataoka, Tanooka &amp; Nakamori, 2022 from Japan in the mouthpart structures (both have 6 rami on mandible and 3 lamellae on maxilla) and the presence of a chaetae s on tubercles L of Abd. I–III. However, the two species differ in a number of characteristics as follows: mandible basal teeth (2 teeth in C. jiuyishanensis sp. nov., 3 teeth in C. laterisensillata); number of dendritic branches on mandible (only 1 dendritic branch in C. jiuyishanensis sp. nov., 2 in C. laterisensillata); number of chaetae s on Ant. IV (6 s in C. jiuyishanensis sp. nov., 8 s in C. laterisensillata); number of chaetae on tubercle Dl of Th. I (2 in C. jiuyishanensis sp. nov., 1 in C. laterisensillata); number of chaetae on tubercles Di of Abd. I–III (3 in C. jiuyishanensis sp. nov., 2 in C. laterisensillata); cephalic tubercles on lateral area (Dl, L and So separated from each other in C. jiuyishanensis sp. nov., Dl, L and So fused together in the latter species); and chaeta s on tubercle L of Abd. IV (absent in C. jiuyishanensis sp. nov., present in C. laterisensillata).</p><p>In Crossodonthina nipponica -group, C. jiuyishanensis sp. nov. has several unique characters, such as: antennal S1 and S2 always absent; chaeta Di2 on head included in tubercle Di; tubercles Di, De and Dl of Th. I with 1, 2, 2 chaetae, respectively; tubercles Di of Abd. I–III each with 3 chaetae, tubercles L of Abd. I–III each with a chaeta s and 6–8 ordinary chaetae. These characters distinguish it from all other known species of the nipponica -group.</p></div>	https://treatment.plazi.org/id/4E6F3663A65B172CFF2DFBB7F7235B9D	Public Domain	No known copyright restrictions apply.

Chaetotaxy of ventral side of abdomen listed in Table 4.</p><p>Remarks. Due to the insufficient original description of Crossodonthina hainana Xiong, Chen &amp; Yin, 2005, it was firstly redescribed by Luo &amp; Chen (2010). Crossodonthina hainana is well characterized within the genus by having two eyes on each side of head, 2/ 6, 2 chaetae on labrum, two chaetae on tubercle Oc, five-branched mandibles and six chaetae on Fu. Undoubtedly, it falls into the C. montana species group (Jiang &amp; Wang 2024). Crossodonthina hainana was firstly described from Dongzhaigang Mangrove Natural Reserve, Hainan Province, China, so it is probably well adapted to saline-alkaline environment of beach habitats. However, its recent discovery in inland China suggests a broader ecological adaptability. So, this species may be widely distributed in the Southern region of China.</p><p>Because most of the characters of our studied specimens from Hunan Province fit the redescription of Luo &amp; Chen, i.e., the similar chaetotaxy on body, the five-branched mandible (with three smooth whip-like and two fringed branches), the similar labral chaetotaxy (2/ 6, 2), and only two chaetae on tubercle Oc, we assigned them to Crossodonthina hainana . However, our redescription reports some minor discrepancies compared to the specimens from Hainan Province sensu Luo &amp; Chen (2010), for example: all macrochaetae are smooth and clavate; the maxillary shortest lamella has 2–3 cilia on its tip; and tubercle De on Th. II has 5 (4+s) chaetae in Hunan’s specimens. Contrarily, the Hainan specimens studied by Luo &amp; Chen (2010) have all macrochaetae ciliated and knobbed; the maxillary shortest lamella has a tooth on its tip; and tubercle De on Th. II has 4 (3+s) chaetae. In this sense, further studies are in need to determine whether specimens from Hunan and Hainan actually belong to the same species.</p></div>	https://treatment.plazi.org/id/4E6F3663A653172AFF2DFD66F7CB5CA0	Public Domain	No known copyright restrictions apply.
