Head relatively small, snout blunt, rounded. Eyes large, not entering dorsal profile of head. Mouth large, upper jaw extending to below rear of eye. Teeth sharp, recurved canines, forming a narrow band of irregular rows up to four teeth long. A wide symphyseal gap present in upper jaw but not in lower. Gill opening apparently above pectoral fin or in front of 1–2 rays. Anus below interopercle, distinctly nearer tip of mandible than to anal fin origin. Pectoral fin of 24–25 rays; notch moderately deep, its rays more widely spaced, rudimentary rays absent. Radials 4 (3+1), rounded. Scapula with helve, coracoid without helve, ventrally notched. Pyloric caeca short, fat. Tongue and mouth both dusky. Scapula and pectoral radials unnotched.

Comparisons. Paraliparis fuscolingua is most similar to P. leucoglossus Andriashev 1986 , but differs in tongue color (dusky vs pale), more anterior position of anus (below preopercle vs below posterior of gill flap), distance from mandible to anus (82–88 vs>100% distance from anus to anal fin origin), gill opening apparently above pectoral fin (vs extending ventrally in front of 5–6 rays), and other characters. It is also similar to P. orbitalis (see that description for comparison).
