Abstract

Taeniacanthid copepods Anchistrotos kojimensis Do and Ho, 1983 were collected from the branchial cavities of stichaeid fish, Ernogrammus hexagrammus (Schlegel) and yellowfin goby, Acanthogobius flavimanus (Temminck and Schlegel) in Korean waters. Here, we provide the first description of a male of Anchistrotos Do and Ho, 1983. A close comparison of the specimens of A. kojimensis collected from Korea with the original description revealed differences in the adult female: (1) the caudal ramus bears seven setae (seta I minute); (2) the maxillule with small knob-like process anteriorly; (3) leg 5 ornamented with patched spinules distally and having row of spinules at base of each spine and distal seta. The first description of the adult male reveals the following features: (1) the distal abdominal somite had rows of spinules anteriorly and near insertion of each caudal ramus; (2) the postantennal process is more elongate than in the female; (3) the basis of maxilliped is with two prosimomedial setae, two longitudinal rows of stout denticles found on posteromedial surface and row of spinules on anteromedial surface; and (4) the second endopodal segment is a strongly curved claw, with a row of stout denticles along a concave margin, two long and one small setae.
