A new species of poecilopsettid flounder, PoecilQpsetta macrocophala, is described based on seven specimens from 550-555m depth on the continental slope off northwestern Australia. This species resembles P. vqynei Quero et al., 1988 and P. natalensis Norman, 1931 in number of lateral Iine scales (75-78), but it can be distinguished from these species in the more-expanded profile above the upper eye; the relatively larger head (26.6 29.6% of SL), shallower body (34.9-37.3e/6 of SL), larger upper
