Abstract

A new righteye flounder, Poecilopsetta pectoralis, is described from 4 specimens (2 males, 2 females) collected from deep waters (510–580 m) around New Caledonia. The species is easily distinguished from 13 congeners by having 99–105 lateral line scales, a narrow interorbit [male: 37.00–40.25 in head length (HL); female: 47.33–50.71], long pectoral fin on ocular side (male: 0.89–0.91 in HL; female: 1.04–1.20), no scales from snout to anterior interorbital region, and 4 spots on caudal fin. Sexual dimorphism is evident in this species, showing males bearing the ocular-side pectoral fin longer than females, and it is the first example in Poecilopsetta.
