Abstract

This paper reports two new record species of deep-sea cusk eels, Dicrolene tristis and Bassozetus multispinis, which were recently collected by Fishery Research Institute of Taiwan from the southern (22°01'N, 120°09'E; 22°11'N, 121°02'E) and eastern (24°16'N. 122°11'E) Taiwan waters at depths more than 1000 m. D. iristis were characterized by two median and a pair of basibranchial teeth patches; B. multispini.s had one basibranchial teeth patch and short pelvic fin ray. The latter species was reported to be only distributed in the Indian ocean at the depths from 1,500-2,000 m.
