Record of Cloridopsis scorpio (Latreille in Latreille, Le Peletier, Serville & Guérin, 1828) (Stomatopoda: Squillidae) from Japan: rediscovery after almost a century

Cloridopsis scorpio (Latreille in Latreille, Le Peletier, Serville & Guérin, 1828) was collected from the intertidal zone of Hiroshima and Okayama Prefectures, western Japan in 2017–2020. This is a rediscovery of the stomatopod crustacean after almost a century in Japanese waters. Morphological characters and coloration of the species are described based on the newly collected specimens. The rostral plate lengthens, and the lateral process of fifth thoracic somite becomes blunted and inclined ventrolaterally with growth. This fact supports that C. aquilonaris Manning, 1978 is a junior synonym of C. scorpio as shown by the previous study.
