A moderately elongate species of Ophichthus with: tail 62%, head 10.3%, and body depth at gill opening 3.4% of TL; dorsal-fin origin above mid-pectoral fin; pectoral fin elongate, but not filamentous, longer than upper jaw; posterior nostril a hole above upper lip, covered by a flap that extends to or below edge of mouth; barbels present behind anterior and posterior nostrils; eye large, its posterior margin in advance of rictus of jaw; pores small but conspicuous, SO 1 + 4, IO 4 + 2, POM 6 + 2; teeth small, close-set and conical, biserial on anterior vomer and jaws; coloration dark gray-brown, paler ventrally, pectoral and median fins black; vertebral formula 11- 53-146. Counts and measurements of the holotype (in mm). Total length 389; head 39.9; trunk 109.1; tail 240; predorsal distance 47; pectoral-fin length 14; pectoral-fin base 3.5; body depth ca. 13.5 at gill openings; body width ca. 14 at gill openings; body depth at anus ca. 12.5; body width at anus ca. 12.5; body depth at branchial basket 18; body width at branchial basket ca. 14.5; snout 8.8; tip of snout to rictus 11.2; snout overhang beyond tip of lower jaw 2.2; eye diameter 3.4; interorbital width 5.2; gill opening height 5.5; isthmus width 9.7.
