Redescription of Xenaploactis asperrima (Günther 1860) (Teleostei: Aploactinidae), based on a specimen from New Ireland, Papua New Guinea

Abstract

The rough velvetfish, Xenaploactis asperrima (Günther 1860), is redescribed on the basis of a specimen trawled in 2014 off northwestern New Hanover, Papua New Guinea, on a steep volcanic rock bottom slope at a depth of 155-120 m. Identification keys to the genera of Aploactinidae, and the species of Xenaploactis Poss & Eschmeyer 1980, are presented.
