Short Report


The rare spookfish Dolichopteryx anascopa Brauer 1901, the original description of which was incomplete due to damage, is redescribed on the basis of the holotype and an additional single specimen collected from south of west Mariana Ridge, western North Pacific. It is easily distinguishable from other species of Dolichopteryx by the tubular eyes with an oval opaque layer on the ventral aspect, anal-fin base originating under the dorsal-fin base, pelvic-fin base inserted at ca. 3/5 of standard length, anus anterior to the dorsal-fin base, elongate pectoral- and pelvic-fin rays, an adipose fin present, 31–32 (= 8 + 1 + 22–23) gill rakers and 43 vertebrae.
