Gomeza serrata Dana, 1852 is a trichopeltariid, not a corystid, and a junior synonym of Peltarion spinosulus (White, 1843) (Decapoda: Brachyura: Trichopeltarioidea)

Abstract

The corystid Gomeza serrata Dana, 1852, described from Patagonia in South America has rarely been reported and its taxonomy is poorly understood. While superficially similar to G. bicornisGray, 1831 from the Indo-West Pacific and the type species of Gomeza Gray, 1931, direct comparisons have not been recorded. Examination of topotypic specimens show that Gomeza serrata is actually a juvenile of Peltarion spinosulus (White, 1843), a member of the family Trichopeltariidae. A neotype is selected for G. serrata to stabilize its taxonomy.
