Abstract / Introduction / Summary:
A female of Parathelges enoshimensis Shiino, 1950 was collected from the abdomen of a hermit crab, Pagurus minutus Hess, 1865 (Paguridae), in the sandy intertidal zone of Lake Hamana, Shizuoka Prefecture, central Japan. This represents the first and third records of Parathelges enoshimensis from Shizuoka Prefecture and Japan, respectively. Only one of the 79 individuals of Pagurus minutus examined from April to December 2019 was infested (prevalence, 1.3%). The female of Parathelges enoshimensis is briefly described. The collection localities of the species in Japan and Korea are affected by a warm current, the Kuroshio, and its branch, the Tsushima Current, respectively.
