Max. size:  31.4 cm (male/unsexed)
Environment:  bathydemersal; marine; depth range 2100 - 2300 m
Distribution:  South eastern Pacific: East Pacific Rise vent site. Possible wider distribution 30° northward and depth range down to 2900m if the individuals filmed at Grommit, Oasis, and Yaquina vent sites are the same species.
Diagnosis:  Slender body than other species, depth 2.9% TL (at pharyngocutaneous duct); paired and median ventral nasal sinus papillae both present, and 10 afferent branchial arteries on the medial ventral aorta; slime pores: 18 prebranchial, 12 branchial, 70 trunk, 19 caudal, total 119; 12 gill pouches and apertures; pharyngocutaneous duct widely separated from the opening of posterior left gill apertures; 3 multicusps in anterior row and 2 in posterior row, total cusps 46; paired dorsal nasal sinus papillae; eyespot absent; body coloration pink.
