Opopaea foveolata was originally described from numerous specimens collected throughout Micronesia, including the types from Guam ( Roewer 1963 ). Tong and Li (2010) misidentified this species as Opopaea sauteri Brignoli, 1974, based on specimens collected from Hainan Island. Baehr et al. (2013) re-described this species from numerous specimens collected from Pacific Islands with detailed descriptions and figures. We re-checked the specimens from Hainan, which sufficiently match the description and illustrations of Baehr et al. (2013) to be confident of their identity. Distribution. Newly recorded from Hainan Island. According to Baehr et al. (2013) , this species is widespread in the Pacific Region and is known from many different islands.
