EE71EBC4DCEF565B84AE5977FDADF1F5.taxon	diagnosis	Diagnosis. Oreonectes damingshanensis sp. nov. is assigned to the genus Oreonectes based on molecular phylogenetic analyses and the following characteristics, which are diagnostic for this genus: (1) anterior and posterior nostrils narrowly separated; (2) lips smooth, with furrows; (3) barbel-like elongation of anterior nostrils longer than depth of nostril tube; and (4) caudal fin rounded, dorsal fin with 6 or 7 branched rays (Du et al. 2023). Oreonectes damingshanensis sp. nov. can be distinguished from all other congeners by the following combination of characters: (1) body pigmentation present; (2) eyes normal, diameter 6.5 - 17.1 % of head length; (3) caudal fin rounded, with irregular black markings; (4) body completely covered with fine scales except for the head; (5) lateral line incomplete, with 14 or 15 pores, last lateral line pore reaching above the tip of pectoral fin; (6) dorsal-fin rays, iii- 7; (7) pectoral-fin rays, i- 9; (8) anal-fin rays, iii- 5; (9) pelvic-fin rays, i- 7; (10) 14 branched caudal-fin rays; (11) tip of ventral fin extended backward, not reaching the anus; (12) dorsal fin origin posterior to the pelvic-fin origin; (13) inrostral barbel extending backward and not reaching the anterior margin of the eye; (14) tip of maxillary barbel not reaching the posterior margin of the gill cover; and (15) vertebrae 4 + 34.	en	Yu, Jing, Luo, Tao, Lan, Chang-Ting, Zhou, Jia-Jun, Deng, Huai-Qing, Xiao, Ning, Zhou, Jiang (2023): Oreonectes damingshanensis (Cypriniformes, Nemacheilidae), a new species of stream fish from Guangxi, Southwest China.

EE71EBC4DCEF565B84AE5977FDADF1F5.taxon	description	Description. Body elongated and cylindrical, with the insignificant depth decreasing from dorsal-fin origin to caudal-fin base. Head short, length 13.3 mm, slightly depressed and flattened, width greater than depth (head width / head depth = 1.3). Snout round, oblique and flat, length 38.0 - 45.3 % of head length (HL). Mouth inferior, curved, upper and lower lips smooth, lower lip with a V-shaped median notch. Three pairs of barbels are long: inrostral barbel length 25.9 - 38.3 % of HL, extending backward and not reaching the anterior margin of eye; outrostral barbel length 42.4 - 62.4 % of HL, extending backward beyond the posterior margin of the eye. Maxillary barbel length 36.0 - 56.6 % of HL, tip of maxillary barbel not reaching to posterior margin of gill cover. Anterior and posterior nostrils narrowly separated, length 33.5 - 84.2 % of eye diameter. Anterior nostril tube short, with an elongated short barbel-like tip. Eyes present, normal, diameter of 6.5 - 17.1 % HL. Gill opening small; gill rakers not developed, nine inner gill rakers on the first gill arch (n = 1) (Fig. 4 D). Dorsal-fin rays iii- 7, pectoral-fin rays i- 9, pelvic-fin rays i- 7, anal-fin rays iii- 5, 14 branched caudal fin rays. Dorsal fin short, length 15.8 - 22.6 % of SL, distally margin round, origin posterior to pelvic-fin insertion, situated slightly posterior to two-thirds the distance between snout tip and caudal-fin base. Pectoral fin short, length 15.2 - 19.5 % of SL, tip of pectoral fin extending backward to ~ 56.7 % of the distance between the origin of pectoral and pre-pelvic fins. Pelvic fin length 13.1 - 17.2 % of SL, tips of pelvic fin not reaching anus, distance between tips of pelvic fin and anus 2.0 times the eye diameter. Anal fin long, length 15.3 - 179.7 % of SL, tips of anal fin not reaching caudal-fin base, distance between tips of anal fin and anus 0.64 times the eye diameter. Caudal fin rounded, caudal peduncle length 9.3 mm, without adipose crests along either dorsal or ventral sides. Vertebrae 38 comprising of 4 Weberian + 22 abdominal + 11 caudal + 1 compound centrum (Fig. 5). Except for the head, body completely covered by scales. Lateral line incomplete, exceeding tip of pectoral fin but not reaching base of caudal fin, with 14 or 15 pores, last lateral line pore reaching above the tip of pectoral fin. Cephalic lateral-line system, with eight supraorbital, 5 + 8 infraorbital canal pores, three supratemporal canal pores, with eight preoperculo-mandibular canal pores. Two chambers of air-bladder, posterior chamber developed, filling the body cavity and connected with anterior chamber by a long, slender tube. Lateral wall of the bony capsule of the swim bladder is membranous and closed posteriorly (Fig. 5).	en	Yu, Jing, Luo, Tao, Lan, Chang-Ting, Zhou, Jia-Jun, Deng, Huai-Qing, Xiao, Ning, Zhou, Jiang (2023): Oreonectes damingshanensis (Cypriniformes, Nemacheilidae), a new species of stream fish from Guangxi, Southwest China.

EE71EBC4DCEF565B84AE5977FDADF1F5.taxon	distribution	Distribution, habitat, and populations. Based on current field surveys, the new species Oreonectes damingshanensis sp. nov. has only been found in streams in the Damingshan Mountains of Mashan and Shanglin counties in the Guangxi Zhuang Autonomous Region of China belonging to the Hongshuihe River basin of the Pearl River system. The new species is easy to collect in the streams of the Damingshan Mountains area where it has a large population.	en	Yu, Jing, Luo, Tao, Lan, Chang-Ting, Zhou, Jia-Jun, Deng, Huai-Qing, Xiao, Ning, Zhou, Jiang (2023): Oreonectes damingshanensis (Cypriniformes, Nemacheilidae), a new species of stream fish from Guangxi, Southwest China.
