Two new species of Notonyx A. Milne-Edwards, 1873 (Crustacea: Decapoda: Brachyura: Goneplacidae) from the Philippines and Fiji

Abstract

Two new species of goneplacid crabs assigned to Notonyx A. Milne-Edwards, 1873 (Crustacea: Brachyura: Goneplacidae) are described from the Philippines and Fiji. Notonyx sagittifer n. sp. from Philippines is superficially similar to N. latus Ng & Clark, 2008, from the Lesser Sunda Islands in Indonesia, but the carapace of the new species is proportionately less broad and the morphologies of the male first and second gonopods are significantly different. Notonyx rayneri n. sp. is closest to N. kumi Naruse & Maenosono, 2009, from Japan and Indonesia but differs markedly in its carapace proportions as well as the structures of the male first and second gonopods. © 2010 Magnolia Press.
