AUTHORSHIP AND DIAGNOSIS OF THE GENUS ARCOTHERES MANNING, 1993 (CRUSTACEA: BRACHYURA: PINNOTHERIDAE)

The pinnotherid generic name Arcotheres was first published by Burger (1895) as a synonym of Pinnotheres Bosc, 1802, and thus is unavailable. The generic name must be attributed to Manning (1993), who first recognized it as a genus distinct from Pinnotheres. The type species is Pinnotheres palaensis Burger, 1895. Nine other species of Pinnotheres named by Burger in 1895 are transferred to Arcotheres. Members of the genus, inhabitants of bivalves, are restricted to the Indo-Pacific region.
