Abstract
A new species, Dolichopteryx rostrata, is described on the basis of a single specimen (66.2 mm in standard length) collected west of the Hebrides Islands, eastern North Atlantic Ocean. The new species is characterized by an elongate snout and head, small pouchlike eyes, an adipose fin, short dorsal fin base, anal fin base originating under dorsal fin base, a clear longitudinal suborbital brownish band extending forward from behind posterior margin of orbit to snout tip, and 41 (=26 + 15) vertebrae. Total fecundity is low; the ovarian eggs number only 473, despite the ovary having developed ova. Ovarian eggs could be clearly subdivided into an “undeveloped group” (0.1–0.7 mm diameter classes, n = 405) and a “developed group” (0.9–1.3 mm classes, n = 68), based on their frequency distribution.
