简单描述
型态特徵 | 形态测量图
背的软条 (总数): 12-13; 臀鳍软条: 8; 脊椎骨: 34. Differs from other species of Psilorhynchus by the presence of large and flap-like skin folds at the lateral corner of the mouth, which reach further posteriorly than the lower jaw cushion and are covered in large 'head of cauliflower' papillae (vs. skin folds not reaching past posteriormost part of lower jaw cushion, non-papilliated or with small dome-like papillae). Can be further diagnosed from other members of P. nudithoracicus species group by the possession of the following characters: two dorsal saddles positioned at dorsal-fin origin; L+2 row present, composed of 5-10 obvious dark brown blotches; mostly 17+17 vertebrae. Can be further separated from P. melissa by its dorsal fin with irregular dark brown or black margins (vs. dorsal fin marked with a dark brown or black band along distal edge); from P. robustus by having dorsal saddles posterior to the dorsal fin poorly developed (vs. dorsal saddles posterior to the dorsal fin well-developed), and by having the anteriormost lateral blotch equal in size or smaller than more posterior blotches (vs. anteriormost lateral blotch larger than more posterior blotches), and from P. tenure by having 9-10+9 principal caudal-fin rays (vs. 9+8); caudal peduncle length 9-13% SL (vs. 14-16% SL); presence (vs. absence) of a short mandibular canal along the anguloarticular; and presence (vs. absence) of a series of indistinct horizontal rows formed by small dark brown spots on the scales above and below the lateral line scale row (Ref. 93866).
Occurs over small pebbles in shallow running waters where the bottom is mainly sand (Ref. 4832). Also found in a slow moving stream with a sandy bed (Ref. 93866).
在底部主要地是沙子的水浅的流动水域中生活在小的小圆石之上。 (参考文献 4832)
