Abstract

Two specimens (332.0~377.6 mm in standard length) of Benthodesmus tenuis (G$\ddot{u}$nther), belonging to the family Trichiuridae, firstly collected in off Heuksan-do and Yeosu, Jeollanam-do by the bottom trawl. This species was characterized by the following morphological traits: 125~126 dorsal fin rays (vs. 144~155 for B. pacificus), I, 73 anal fin rays (vs. 91~101), interorbital region flat (vs. interorbital region with prominent crest for A. anzac), opercular black and caudal fin forked. We propose a new Korean name, "Se-jang-gal-chi-sok" and "Se-jang-gal-chi" for the genus and species, respectively.
