摘要
The parasitic isopod genus Scyracepon Tattersall, 1905 is recorded from China for the first time, and a new species, Scyracepon distincta, is described from the host Jonas distinctus (Brachyura: Corystidae). Females of the new species can be distinguished from those of the other six species of Scyracepon by their subequal mid-dorsal projections on pereomeres 6 and 7 (lacking on other pereomeres) and pleonal segments with medial but not lateral fusion. Males of the new species have the first two pleomeres free, pleomeres 35 fused, and bear midventral tubercles on all pereomeres and the first pleomere. This is the first record of any species of Corystidae bearing parasitic isopods. Remarks on, and a key to, the seven known species of Scyracepon are provided.
