Claea dafangensis sp. nov. can be distinguished from C. scet by the processus dentiformis prominent, covering lower jaw when mouth shut (vs. reduced, not covering lower jaw when mouth shut), body pigmentation present (vs. reduced), eyes normal, with diameter 10.9–21.0 % of head length (HL) (vs. eyes reduced, 3.8–5.9 % HL); from C. minibarba by tip of maxillary barbel reaching the posterior margin of eyes (vs. extending to the middle of eye), 8–9 branched pectoral-fin rays (vs. 10), and caudal-peduncle depth 6.1–8.7 % SL (vs. 9.5–11.7 %); from C. wulongensis by tip of maxillary barbel reaching the posterior margin of eye (vs. extending to ansterior margin of eye), 16 branched caudal-fin rays (vs. 18), and interorbital width 23.6–39.0 % HL (vs. 38.5–43.1 %); from C. dabryi (Fig. 6) by outrostral barbel backward extending beyond the anterior nostrils (vs. reaching or beyond to ansterior margin of eye), tip of maxillary barbel reaching the posterior margin of eye (vs. beyond the posterior margin of eye), and anal fin base length 4.0–5.5 % SL (vs. 2.8–3.4 %).</p><p>Description.</p><p>Morphometric measurements of Claea dafangensis sp. nov. are summarized in Suppl. material 1.</p><p>Body elongated, anteriorly subcylindrical and posteriorly gradually compressed from dorsal fin to caudal-fin base, with maximum body depth at dorsal-fin origin, deepest body depth 8.8–15.5 % of SL. Dorsal profile is not clearly elevated from snout to dorsal-fin insertion, and then straight from posterior portion of dorsal-fin origin to caudal-fin base. Head depressed, length 15.7–23.5 % SL, Snout moderately blunt, length approximately 28.3–64.7 % HL. Mouth inferior arched and curved, mouth corner situated below anterior nostril, upper and lower lips smooth, with thin lips exhibiting shallow surface furrows, and lower lip with V-shaped median notch. Processus dentiformis prominent, covering lower jaw when mouth shut. Anterior and posterior nostrils closely located; anterior nostril tube short, no distinct barbel-like at the tip of the anterior nostril, tip of posterior nostril backward extending not reaching to anterior margin of orbit. Three pairs of barbels, inner rostral barbel short, length 13.1–28.5 % HL, backward extending not reaching the corner of the mouth; outrostral barbel short, length 16.2–51.1 % HL, backward extending not reaching posterior margin of eyes, but beyond the anterior nostrils. Tip of Maxillary barbel reaching the posterior margin of eyes, length 18.6–43.8 % HL. Eyes normal, with diameter 10.9–21.0 % HL.</p><p>Dorsal-fin rays iii, 8 (n = 14), pectoral-fin rays i, 8 (n = 6) – 9 (n = 8), pelvic-fin rays i, 6 (n = 14), anal-fin rays iii- 5 (n = 14), and 16 (n = 14) branched caudal-fin rays. Dorsal fin short, length 12.7–19.5 % SL, distal margin truncated, origin posterior to pelvic-fin origin and situated slightly posterior to the midpoint between snout tip and caudal-fin base; first branched ray longest, shorter than head length; tip of the dorsal fin is located vertical but slightly in front of the anus. Pectoral fin short, length 13.8–18.3 % SL, tip of pectoral fin backward extending almost to midpoint between origin of pectoral and pelvic-fin origins, not reaching to pelvic-fin origin. Pelvic fin short, length 10.1–14.7 % SL, vertically aligned with third branched ray of dorsal fin, tips of pelvic fin not reaching the anus. Anal-fin length 11.3–14.9 % SL, distal margin truncated, origin slightly separated form the anus, tips of anal fin not reaching caudal-fin base, Caudal fin forked, upper lobe slightly longer than lower lobe, caudal peduncle length 8.0– 17.2 mm, caudal peduncle depth 3.0– 6.7 mm, with weak adipose crests along both dorsal and ventral sides.</p><p>Body scaleless. Cephalic lateral-line system developed, with 7–9 supraorbital, 4–5 + 11–12 infraorbital canal pores, 3–4 supratemporal canal pores, with 9–10 preoperculo-mandibular canal pores. Lateral line complete and nearly straight, extending from behind extremity of gill opening along mid-lateral body to terminate middle caudal-fin base. Stomach U-shaped; intestine short, zigzag in shape posteriorto stomach. Two chambers of air bladder; anterior chamber enclosed in a dumbbell-shaped bony capsule and posterior chamber nearly completely degenerated (Fig. 4 K).</p><p>Coloration.</p><p>In freshly collected individuals (Fig. 5 A), the body of living fish is yellowish, with irregular dark black patches on the head and body. After fixation in a 10 % formalin solution, the body color was pale grey, and the dark-brown patches on the head and body were more prominent.</p><p>Secondary sex characteristics.</p><p>No secondary sex characteristics were observed based on the present specimens of Claea dafangensis sp. nov.</p><p>Ecology and distribution.</p><p>Claea dafangensis sp. nov. has only been found in a surface pool fed by a cave in Longtan Village, Yuchong Town, Dafang County, Guizhou Province, China, at an elevation of 1376 m. The pool where the new species was found is more than 21 m long and 20 m wide, with a slow flow of water, and it is located at the entrance of the cave. Inside the pool, tadpoles of Oreolalax rhodostigmatus were found. Beside the pool, rapeseed was being grown.</p><p>Etymology.</p><p>The specific epithet “ dafangensis ” refers to the type locality of the new species, distributed in Dafang County. We propose the common English name “Dafang mountain loach” and the Chinese name “ Dà Fānɡ Shān Qīu (大方山鳅). ”</p></div>	https://treatment.plazi.org/id/3DEFD7DF246E5A788D5309FEA7C273B2	Public Domain	No known copyright restrictions apply.
