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.
