Sesarmidae Dana, 1851

Castro, Peter, 2011, Catalog of the anomuran and brachyuran crabs (Crustacea: Decapoda: Anomura, Brachyura) of the Hawaiian Islands 2947, Zootaxa 2947 (1), pp. 1-154 : 119

Family Sesarmidae Dana, 1851

Genus Armases Abele, 1992

(*) Armases rubripes Rathbun, 1897

Sesarma trapezium Dana, 1852b: 354, 1577 , pl. 22, fig. 8 [type locality: “Sandwich Is.;” type material presumed lost].

Additional Hawaiian Is. records:

Sesarma (Holometopus) trapezium Dana, 1852 — Rathbun 1906: 841 [Dana’s record], Edmondson 1946: 307 [Dana’s record].

Metasesarma trapezium (Dana, 1852) — Edmondson 1959: 186, fig. 18 [Dana’s record].

Remarks. Sesarma trapezium was described from the Hawaiian Is. but not reported from the archipelago or elsewhere since, while Armases rubripes Rathbun, 1897 , is a western Atlantic species. It is thus possible that the Hawaiian Is. locality of the type material is erroneous. The name Sesarma rubripes Rathbun, 1897 , was given priority over the name Sesarma trapezium Dana, 1852 , by the ICZ (see Ng et al. 2008: 220, 223, note 2).
