This species is distinguished by the following set of characters: rhombic disc which is wider than long, width about 2.2-times TL; disc length 58%-64% of DW; anterior margin of disc joining head behind orbits; head clearly protruding from disc, eyes in lateral position, moderate in size; snout width equal to interorbital distance (13.6%-16.5% DW), mouth relatively wide, as broad as distance between 5th gill slits (mouth width 0.8-1-times distance between 5th gill slits); mouth width greater than distance between inner ends of nostrils (1.5-1.6- times); distance between 5th gill slits greater than distance between inner ends of nostrils (1.8-1.6-times) (Ref. 91774).

Male and female mature at approximately 50.0-60.0 mm DW (Ruocco, unpubl. data), and males are typically smaller than females (Ref. 91774).
