Hyperacanthomysis, a new genus for Acanthomysis longirostris Li, 1936, and A. brevirostris Wang & Liu, 1997 (Crustacea: Mysidacea: Mysidae).
A new mysid genus, Hyperacanthomysis, is proposed to receive Acanthomysis longirostris li, 1936, and A. brevirostris Wang & Liu, 1997. The new genus differs distinctly from Acanthomysis Czerniavsky, 1882, in the following characters: the remarkably short distal segment of the exopod of the male fourth pleopod and the triangular or narrowly linguiform telson. The new genus is also distinguished from related genera of Acanthomysis and the remaining species belonging to Acanthomysis s. I. by the combination of the following characters: the multi-segmented carpopropodus of the third to eighth thoracic endopods, the long 2-segmented exopod of the fourth male pleopod, and the telson with an unarmed portion between two spine groups on the lateral margin. Acanthomysis bowmani Modlin & Orsi, 1997, from Californian waters, is judged to be a junior synonym of H. longirostris, and may be a naturalized species introduced from East Asian waters.
