Diagnostic Description

provided by Fishbase
Schizothorax beipanensis is distinguished from all congeners by the combination of the following characters: absence of horny sheath on the lower jaw; upper lip developed; lower lip developed, trilobed; postlabial groove continuous, with a minute median lobe. Schizothorax beipanensis can be distinguished from S. griseus by the absence (vs. presence) of black spots on the flank, along the lateral line; distal 20-25 % of the last unbranched dorsal-fin ray soft (vs. strong); rostral barbel not reaching (vs. reaching) the middle of the eye; eye diameter 58.5-120.1 % length of maxillary barbel (vs. 33.4-93.7 %). Schizothorax beipanensis is most similar to S.heterophysallidos, from which it is distinguished, however, by the unique air bladder of the latter (Ref. 80483).
