Short description
आकृति विज्ञान | मौरफोमैटरिक्स
This species has the following characters: flattened prenarial snout, apparently longer than interorbital width; furrows of upper labial much longer than the lower ones; pectoral fin widely expanding posteriorly, with outer margin a little longer than P1-P2 space; short abdomen, P1-P2 space narrower than preorbital length or anal fin base length; origin of first dorsal-fin just above or slightly anterior to pelvic-fin insertion; 50–64 and 48–68 tooth rows on upper and lower jaws, respectively; teeth with 5 or more cusps, including the anterior ones; egg capsule with no coiled tendrils on anterior and posterior ends, posterior end tapering toward tip; color preserved in alcohol is uniformly pale brownish to light greyish, sometimes light yellowish brown; the dorsal side of body is a little darker than ventral side (Ref. 76943).
