51D6BE3A2C005A45BA211CDF035877D5.taxon	etymology	Etymology. The species name, qinae, is in recognition of the contributions of Zi-Shan Qin to the collection of the present specimens and dedicated efforts in fieldwork. We suggest the Chinese vernacular name “ 覃氏岭鳅 ”.	en	Chen, Zhuo-Ni, Mo, Cai-Huan, Du, Li-Na, Zhang, Li-Na (2025): Oreonectes qinae (Teleostei, Cypriniformes, Nemacheilidae), a new loach species from Guangxi, China.

51D6BE3A2C005A45BA211CDF035877D5.taxon	diagnosis	Diagnosis. This new species can be distinguished from all known species of Oreonectes by a combination of the following characteristics: color pattern present; swim bladder degenerated; black longitudinal stripe from posterior upper pectoral fin to caudal-fin base; dorsal-fin origin posterior to pelvic-fin origin; tip of pelvic fin not reaching anus; caudal fin with irregular black markings; caudal fin rounded; maxillary barbel not reaching posterior margin of opercula; without dark brown V-shaped marking on dorsal surface of head; 16 branched caudal-fin rays; and 12 inner-gill rakers on first gill arch.	en	Chen, Zhuo-Ni, Mo, Cai-Huan, Du, Li-Na, Zhang, Li-Na (2025): Oreonectes qinae (Teleostei, Cypriniformes, Nemacheilidae), a new loach species from Guangxi, China.

51D6BE3A2C005A45BA211CDF035877D5.taxon	description	Description. The morphometric and meristic data of Oreonectes qinae sp. nov. are provided in Table 1. Body elongated and cylindrical (Fig. 1 A), slight elevation of head-dorsal junction, deepest body depth 13.2 % – 19.8 % of SL, deepest body depth anterior to dorsal-fin origin, decreasing depth from dorsal-fin origin to caudal-fin base, dorsal-fin origin closer to the posterior margin of the operculum than to caudal-fin base. Head flattened, head width longer than height, head width 60.9 % – 72.6 % of HL, head height 43.5 % – 54.5 % of HL. Whole body covered by scales, except head and thorax. Dorsum of head and above lateral line dark gray. Lighter color below lateral line and abdomen, without body color spots. Mouth inferior, curved, processus dentiformis absent, jaws completely covered by lips (Fig. 1 H), snout length shorter than postorbital length of head, visible wrinkles present on surface of lip, lower lip with V-shaped median notch completely interrupted by longitudinal groove (Fig. 1 C). Anterior and posterior nostrils closely adjacent, base of anterior nostril tubular, tip elongated to whisker-like, nostril barbel length 90.4 % – 140.2 % of eye diameter. Three pairs of barbels, well-developed, inner rostral barbel length 30.2 % – 39.1 % of HL, reaching anterior nostril; outer rostral barbel length 47.3 % – 57.3 % of HL, extending to posterior margin of eye; maxillary barbel length 40.8 % – 50.9 % of HL, not reaching posterior margin of opercula. Eyes normal, interorbital width greater than eye diameter, eye diameter 13.0 % – 22.5 % of HL. Tip of pelvic fin close to, but not reaching, anus (Fig. 1). Dorsal-fin origin posterior to pelvic-fin origin. Distance between anus and tip of anal fin 0.9 – 2.0 times eye diameter. Caudal fin rounded. Caudal-peduncle length greater than width, caudal-peduncle depth 76.0 % – 99.4 % of length, adipose crests along both dorsal and ventral sides absent. Three unbranched and seven to eight branched dorsal-fin rays, dorsal-fin rays dark, membrane transparent and scattered with black pigments, two unbranched and nine to 10 branched pectoral-fin rays, two unbranched and six to seven branched pelvic-fin rays, three unbranched and five branched anal-fin rays, 16 branched caudal-fin rays. Inner-gill rakers on first gill arch 12 (2). Cephalic lateral-line system well-developed, 9 – 10 + 4 infraorbital pores, 7 – 8 supraorbital canal pores, six supratemporal canal pores, 9 – 10 preoperculo-mandibular canal pores. Lateral line incomplete, with 11 – 13 lateral-line pores, last lateral-line pore not reaching tip of pectoral fin. Posterior chamber of swim bladder degenerated, only 1.5 times eye diameter (Fig. 2 A). Stomach U-shaped, intestine curved along stomach, leading directly to anus (Fig. 2 B).	en	Chen, Zhuo-Ni, Mo, Cai-Huan, Du, Li-Na, Zhang, Li-Na (2025): Oreonectes qinae (Teleostei, Cypriniformes, Nemacheilidae), a new loach species from Guangxi, China.

51D6BE3A2C005A45BA211CDF035877D5.taxon	distribution	Distribution and habitat. Oreonectes qinae sp. nov. is currently only known from Gutingshan Forest Park, Youfeng District, Liuzhou City, Guangxi Zhuang Autonomous Region, China, in the Liujiang River drainage (24.32325 ° N, 109.51695 ° E) (Fig. 4 A). The species inhabits small streamlets with water depths ranging from 0.5 to 1.5 m, characterized by rocky substrate and abundant macrophyte growth, providing suitable habitat conditions (Fig. 4 B). Other aquatic species observed in the same streamlet include the crab Qianguimon splendidum Huang, 2018, and the shrimp Caridina huananensis Liang, 2004; there is no other fish in the habitat.	en	Chen, Zhuo-Ni, Mo, Cai-Huan, Du, Li-Na, Zhang, Li-Na (2025): Oreonectes qinae (Teleostei, Cypriniformes, Nemacheilidae), a new loach species from Guangxi, China.
