Dorsal body profile rising smoothly from nostrils to occiput, almost horizontal between occiput and dorsal-fin insertion, gradually sloping along dorsal-fin base, then horizontally extending to caudal-fin base. Maximum body depth at dorsal-fin origin, body depth 12.6–19.8 % of standard length. Lower surface of head flattened, abdomen rounded. Caudal peduncle short, depth almost equal to length, laterally compressed, with fleshy keels on dorsal and ventral sides. Head length greater than body depth (101.0–156.7 % of head length); snout elongated and blunt, snout length 36.9–50.1 % of head length; eye small, 11.2–20.3 % of head length, superior and laterally positioned, near gill opening than tip of snout; nostrils positioned close together, anterior nostril with short tube; interorbital region ridged and narrow. Anus positioned near anal-fin insertion. +Mouth inferior, lips fleshy. Upper lip without affiliated apparatus; lower lip two lobed, medial side elongate-oval shaped. Three pairs of barbels: rostral barbels shorter than maxillary and mandibular barbels; maxillary barbels length equal to mandibular barbels length; mandibular barbels not or almost reaching under the anterior edge of the orbit. + +Body covered with tiny cycloid scales.

Four obvious lines of Gambetta’s pattern. The L +1 +of Gambetta’s pattern on the dorsal of body, 7–10 black blotches before dorsal-fin insertion, 7–11 black blotches after dorsal-fin base end; L +2 +not exist or fused with L +1 +; L +3 +linear, interrupted into several small irregular blotches and fused with L +1 +at caudal peduncle; L +4 +linear, consisted of many tiny spots; L +5 +obvious, extending along the mid-lateral side of body, consisted of 9–15 different sized black blotches, sometimes connected with each other with black strip. Three or four rows of pigmentation on dorsal-fin rays; three or four arcuate black bars on caudal fin. One big jet-black oval-shaped spot on upper caudal-fin base, size comparable to the eye diameter (Fig. +4 +). + + + + + + +Live individuals of + +Cobitis beijingensis + +sp. nov. +A. +Holotype, +ASIZB +240630, male; +B. +Uncatalogued, female; +C. +Paratype, +ASIZB +240682, male, photographed in aquarium. + + + + + +Coloration in preservation. + +Dorsal side of head and body yellow, mid-lateral side light yellow, ventral side pale. All patterns same position as living specimen. + + + +Sexual dimorphism. + + +Males with elongated lamina circularis derived from the base of the first branched pectoral-fin ray; tip of the lamina circularis almost reaching the mid-point of the first branched ray; posterior margin of the lamina circularis usually serrated (Fig. +5 A +). The L +4 +of Gambetta’s pattern in males, usually thin and short, sometimes disappeared. The blotches on L + +5 +in + +males usually merged into a line. Females usually larger and slender than males. The L + +4 +in + +females usually exceeds over dorsal fin insertion, sometimes reaching the caudal peduncle. The blotches on L + +5 +in + +females not fully merged into one line. + + + + + + +Lamina circularis of + +Cobitis beijingensis + +sp. nov. +( +A +) and + +C. lutheri + +( +B +). + + + + + +Distribution. + + +Based on our field collections and the historic specimens, + +Cobitis beijingensis + +is distributed in the Haihe River basin in northern +China +, including rivers in +Beijing +and the Baiyangdian Lake in +Hebei Province +. This species can be currently found in the Chaobaihe River system in Huairou and Miyun District, +Beijing +(Fig. +6 +). + + + + + + +Distribution of + +Cobitis beijingensis + +sp. nov. +and + +C. lutheri + +; the zoom-in map shows detailed distribution (i. e., specimen locality records) of the new species in Beijing and the adjacent area. + + + + + +Habitat and biology. + + +This species usually inhabits slow-flowing water or still water with plenty of submerged plants or filamentous algae. The benthic microhabitat is usually sand and silt mixed with some gravel. Coexisting species include + +Rhodeus ocellatus + +, + +Carassius auratus + +, + +Misgurnus anguillicaudatus + +, + +Oryzias latipes + +, + +Rhinogobius giurinus + +, etc. + + + + +Etymology. + + +The species name + +“ +beijingensis + +” was referred to the type locality of this species, +Beijing +, the capital city of +China +. The Chinese name for the new species is “ 北京花鳅 ”. + + + + +Genetic comparisons. + + +A total of 24 haplotypes from 30 + +Cobitis + +individuals were included in the analyses. The molecular phylogenetic results ( +BI +and + +ML + +trees in Fig. +7 +) based on mitochondrial Cyt +b +sequences show that the new species + +C. beijingensis + +forms a monophyletic group itself, which is sisters to the group consists of + +C. lutheri + +, + +C. tetralineata + +, + +C. nalbanti + +, and + +C. hankugensis + +. The interspecific genetic distances between + +C. beijingensis + +and four congeners, + +C. lutheri + +, + +C. tetralineata + +, + +C. nalbanti + +, and + +C. hankugensis + +, are 13.1 %, 8.0 %, 12.5 %, and 8.3 %, respectively (Table +3 +). The intraspecific genetic distances in + +C. beijingensis + +, + +C. lutheri + +, + +C. tetralineata + +, + +C. nalbanti + +, and + +C. hankugensis + +are 0.2 %, 0.5 %, 0.0 %, 0.6 %, and 0.0 %, respectively (Table +3 +), which are much lower than the interspecific genetic distances. The molecular phylogenetic results support + +C. beijingensis + +to be a distinct species. + + + + + + +Genetic distances of the Cyt +b +gene computed by MEGA 6.0 amongst nine analyzed species of + +Cobitis + +, + +Sabanejewia aurata + +was used as the outgroup. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
