Short description
Κλείδες προσδιορισμού | Μορφολογία | Μορφομετρία
Σπόνδυλοι: 33. Distinguished from other species of the genus Yunnanilus by the unique color pattern and the elongated papillae on upper and lower lips. Differs from closely related species Yunnanilus pleurotaenia by the following morphometric characters: standard length/body depth 4 .3-5.6 vs. 3.9-4.9; standard length/head length 4.4-5.1 vs. 3.7-3.9; standard length/caudal-peduncle length 5.7-7.1 vs. 7.7-9.1; head length/snout length 2.7-3.5 vs. 2.5-2.8; caudal-peduncle length/depth 1.2-1.7 vs. 1.1-1.2 (Ref. 76753).
Inhabits underground river (Ref. 76753).
