Crustacea copepod Taeniacanthidae flatfishes parasite taxonomy

Abstract

A new taeniacanthid genus, Biacanthus gen. n., is proposed for Taeniastrotos pleuronichthydis (Yamaguti, 1939) based on a redescription of adult female and male specimens collected from three flatfish hosts captured along the coast of Japan. Biacanthus pleuronichthydis (Yamaguti, 1939) comb. n. is distinguished from other taeniacanthid species by a combination of characters that include a horseshoe-shaped sclerotised structure on the ventral surface of the rostrum, an anteromedial projection on the first antennule segment, an uncinate process posterior to each antennule base, a pair of postantennal processes, a sigmoid-shaped maxilliped claw bearing an accessory process, an inner coxal seta on legs 2 and 3, and an inner intermediate spine on the first and second endopodal segments of leg 4. A key to the genera of the Taeniacanthidae females is provided.
