S2.8  Sunday, Jan. 4  A review of bopyrid isopods infesting crabs from China AN, J.; Shanxi Normal Univ. anjianmei@hotmail.com

Isopod parasites of the subfamilies Ioninae and Pseudioninae are known to infest the branchial chambers of brachyuran crabs. In total, 20 species of parasitic isopods infest crabs from China, belonging to 6 genera from the Ioninae and 1 genus from the Pseudioninae. Specifically, the following genera are represented: Allokepon Markham, 1982 (3 species), Apocepon Nierstrasz & Brender Brandis, 1930 (3 species), Cancricepon Giard & Bonnier, 1887 (1 species), Dactylokepon Stebbing, 1910 (5 species), Gigantione Kossmann, 1881 (4 species), Onkekepon An et al., 2006 (2 species) and Tylokepon Stebbing, 1906 (2 species). A new species of Tylokepon from Menaethius monoceros (L.) collected in China is distinguished from other members of the genus by two projections on pereomere 6, and entire pleopods and uropods without any tuberculate on their surface. A list of all brachyuran species (34 species in nine families) so far recorded as bopyrid hosts in Chinese waters, with their parasites and localities will be discussed.
