Pelvic fin rays 8-9; first dorsal fin dusky proximally, paler distally, no distinct black blotch or streak; a dark streak along leading edge of snout, with a median extension atop snout; barbel 22-35% of head length, about 75-130% of orbit diameter; orbit diameter 1.3-2.1 into postorbital length of head; outer premaxillary teeth distinctly enlarged, mandibular teeth in two irregular rows; ground color of body in preserved specimens light brown, dorsum of trunk and tail not strongly demarcated from lateral and ventral surfaces; suborbital shelf broad, not constricted anteriorly, blackish streak covers shelf broadly or narrowly, but confined along dorsal portions. Snout protruding, angular.
A benthic species found on the continental slope (Ref. 75154).
