| Diagnosis |
This species is distinguished from its congeners by the following set of characters: moderately deep, elongate, and laterally compressed body; long head compared to the other two congeneric species, longest among the three; post-nostril region of the head dorsal distinctly convex and the pre-nostril region almost straight; interspace between head posterior and first dorsal origin very narrow, narrowest among the three; maxilla relatively long, reaching beyond the posterior margin of pupil and stop midway to posterior margin of the eye; snout long, with distinct bird-beak-like appearance; and eye diameter shorter than snout (Ref. 137856). |
