Short Description
This species is distinguished by the following characters: wedge-shaped disc, its dorsal surface scaled but no thorns; snout length 2.5-2.6 times interspiracular distance; orbit moderately large, diameter 1.6-1.9 times spiracle length; nostrils oblique, length 1.4-1.6 times internarial distance; anterior nasal-flaps inserted well into internarial space, but never almost united near ventral midline; posterior nasal flaps broad; ridges of rostral cartilage well-separated dorsally and almost parallel; prebranchial sensory-pore patch narrow, extending to first gill slit; distance between first gill slits 1.3-1.4 times distance between fifth gill slits; distance between fifth gill slits 2.5-2.9 times in ventral head length; postscapular sensory canal long, not grooved, extending more than three-quarters distance to pectoral-fin insertions; moderately tall dorsal-fins; pelvic-fin inner margin distinctly longer than its base in mature males, shorter than base in females; interdorsal distance more than 2.5 times first dorsal-fin base; outer spiracular fold distinctly larger than inner fold; dorsal margin of caudal fin about 2.0-2.2 times preventral margin; 162-171 post-synarcual vertebral centra; about 50 nasal lamellae; dorsal disc plain brownish or with faint dusky blotches or fine dark spots (Ref. 58070).
