Abstract

Species of the genus Poromitra belonging to the P. megalops group are considered on a large collection material. These species are characterized by small sizes (up to 6 cm), oblong body, elongated caudal peduncle, large eyes, four scales on the cheek, bony crests of the anterior margin of the praeoperculum located at a right angle towards each other, and other features. Until recently it was considered that P. megalops (Lütken) has a circumtropical range. This study demonstrated that P. megalops occurs only in the Atlantic Ocean. In the Indian Ocean and the central part of the Pacific Ocean, P. macrophthalma (Gilchrist) dwells. A new species P. jucunda Kotlyar sp. nova is described from the eastern and central parts of the Pacific Ocean. A key to 22 known species of the genus Poromitra is provided at the end of the paper.
