Diagnosis

Differs from Rhynchodoras xingui by having the following characters: all three tympanal scutes weakly developed (vs. second and particularly third well developed, latter with medial carina); midlateral scutes 34-36 (vs. 33 -34); and anterior midlateral scutes relatively shallow,

depth about one-fifth of corresponding body depth, and with dorsal and ventral laminae weakly developed, lacking distinct serrations along posterior margins (vs. depth about one-third to one-quarter of corresponding body depth, and dorsal and ventral laminae well developed with conspicuously serrated posterior margins). Diagnosed from Rhynchodoras woodsi by having a simple swim bladder (vs. each posterior chamber of

gas bladder expanded into elongate horn-like diverticulum), and tubercles punctate and abundant (vs. tubercles elongate, dashlike, and sparse) (Ref. 72419).

Description: A iii-iv,8-9; V i+6 (Ref. 72419).
