Full paper


A new bothid flounder, Engyprosopon marquisensis, is described from 11 specimens collected in deep waters (108–408 m) off the Marquesas Islands (French Polynesia) during the French exploratory cruise MUSORSTOM 9 in 1997. Engyprosopon marquisensis is similar to E. bellonaensis from the Chesterfield Islands and Bellona Plateau in the Coral Sea and E. vanuatuensis from off Vanuatsu Island, but is easily distinguished from E. bellonaensis by the following combination of characters: narrow interorbital space in both sexes, small mouth, short caudal fin, large number of vertebrae, and fewer gill rakers. It differs from E. vanuatuensis by many scales in the lateral line, small eyes, short ocular-side upper jaw, and short blind-side lower jaw. Engyprosopon marquisensis is the deepest occurring (408 m) species of the genus, and constitutes the second species of this genus with an eastern distribution.
