A new species of Cancricepon Giard & Bonnier, 1887 (Isopoda: Bopyridae) from China.

Specimens of the genus Cancricepon Giard & Bonnier, 1887 are recorded for the second time from China, and a new taxon, Cancricepon multituberosum n. sp., is described based on specimens parasitising the xanthid crab Liomera laevis (A. Milne-Edwards). Females of the new species can be distinguished from the other seven species of Cancricepon by the presence of mid-dorsal projections on all pereomeres and the absence of a palp on the maxilliped. Merocepon knudseni Danforth, 1970 is transferred to Cancricepon as C. knudseni (Danforth, 1970) n. comb. A table of the eight described species of Cancricepon is provided.
