A new deep-sea species of the caridean shrimp genus Lebbeus White, 1847 (Crustacea: Decapoda: Thoridae) from southern Java, Indonesia

Abstract

A new species of the thorid genus Lebbeus White, 1847, L. java new species, is described on the basis of two ovigerous female specimens from south of Java, Indonesia, collected at depths of 637-689 m. It is morphologically most similar to L. formosus Chang, Komai & Chan, 2010, known from off Taiwan, amongst about 70 congeners, but subtle morphological differences and genetic divergence estimated from the barcoding segments of the mitochondrial COI gene warrant the recognition of the new species. The new species is the third representative of Lebbeus from Indonesian waters.
