In this study, we have identified a new endoparasitic isopod species, Portunion sinensis sp. nov., from the hemocoel of Scylla paramamosain. Portunion sinensis sp. nov. is similar to Portunion conformis in having the anterior vertical to thorax, the posterior directed backwards for Female's ventral processes.However, the new species can be distinguished from P. conformis by the rudimentary abdominal spines present on segment Ⅲ-Ⅳ in males. Herein we describe a detailed morphological description of this new species and conduct an extensive comparison with related species. This study marks the first description of P. sinensis sp. nov. of an endoparasitic isopod species found in Scylla paramamosain in China.
