Etymology: Gymnoamblyopus: Greek, gymnos = naked (or bare) + Greek, ambly = dark + Greek, pous = feet (or for Amblyopus, the generic basis of the subfamily name; referring to the absence of the scales of the fish; masculine Ref. 45979).; novaeguineae: From the type locality, the island of New Guinea; noun in apposition.
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Tropical

Absence of the following: Y-shaped second anal-fin pterygiophore, chin barbels, scales, raised dermal folds or ridges, and cephalic sensory canals and pores. Short pleural ribs posteriorly directed. Vertical mouth large; lips fleshy especially at rictus. Eyes rudimentary, but distinct; covered by skin. Posterior naris lateral to, and slightly anterior to, eye. Anterior naris at tip of small flap of skin overhanging upper jaw. Dorsal-fin base long and broadly joined with caudal fin; anal-fin membrane also broadly joined with caudal fin.
