كليدهاي شناسايي | ريخت شناسي | ريخت ستجي بوسيله انداره گيري
This species is distinguished from its congeners by the following set of characters: body brownish or greyish with a narrowly wedge-shaped disc; a long narrow bluntly pointed snout (angle 31-40°); broad oblique nostrils with the narrow anterior opening; nostrils about half of the mouth width, subequal (0.98-1.33) to internasal width; ~55-57 nasal lamellae; anterior nasal flaps are slightly penetrating into internasal space, their interspace 2.20- 2.61 in length of the posterior nasal aperture; in adults the orbit is very small, diameter 8.19-11.62 in preorbital length, 2.25-2.69 in interorbital space; rostral ridges are almost joined along their entire length; margin of cranium sharply demarcated before eyes; spiracular folds are very short and widely separated; rough skin densely covered with small denticles, more coarsely granular on the dorsal surface than ventrally, enlarged between orbits and in a distinct band between nape and first dorsal fin; tail relatively longer, its length 1.15-1.48 in disc length; dorsal fins narrowly spaced, interspace 1.32-2.11 in base length of the first dorsal fin; clasper length in adult male 4.37-5.70 in total length (Ref. 125646).
