A review of the genus Parapenaeon Richardson, 1904 (Crustacea: Isopoda: Bopyridae: Orbioninae), with description of three new species from China

Abstract

Five species of the bopyrid genus Parapenaeon are reported from China, of which three are new to science, and one, Parapenaeon expansa Bourdon, 1979, is a new record. New species are Parapenaeon calculosa, sp. nov., Parapenaeon diatropa, sp. nov. and Parapenaeon sicyoniae, sp. nov., from the East and South China Seas. The female of each new species has six pleomeres, no lateral plates on the sixth pleomere, and biramous uropods, characters that place them in the genus Parapenaeon Richardson, 1904. Each can be distinguished from previously described species of the genus Parapenaeon in body shape, by the characters of oostegite 1, the barbula, brood pouch, pleopods and uropods of the females. A table including all of the currently recognized species of Parapenaeon with type localities, known geographical distribution and reported hosts, is given. A key to the recorded species of Parapenaeon Richardson, 1904 is provided, as is a new diagnosis of the genus.
