New records of Glyphocrangon A. Milne-Edwards, 1881 (Crustacea, Decapoda, Caridea, Glyphocrangonidae) from recent French expeditions off the Mozambique Channel and Papua New Guinea, with description of one new species

Abstract

Collections made during recent French expeditions off the Mozambique Channel in the western Indian Ocean (MAINBAZA, MIRIKY) and off Papua New Guinea in the southwestern Pacific (BIOPAPUA) yielded a total of 14 species of the deep-water shrimp genus Glyphocrangon A. Milne-Edwards, 1881, including one new to science: G. amblytes Komai, 2004, G. assimilis De Man, 1918, G. brevis Komai, 2006, G. confusa Komai, 2004, G. crosnieri Komai, 2004, G. dentata Barnard, 1926, G. faxoni De Man, 1918, G. indonesiensis Komai, 2004, G. lowryi Kensley, Tranter & Griffin, 1987, G. proxima Komai, 2004, G. pugnax De Man, 1918, G. pulchra n. sp., G. rudis Komai, 2006, and G. speciosa Komai, 2004. Glyphocrangon pulchra n. sp. belongs to the “G. regalis Bate, 1888” species-complex, and differentiating characters between the new species and closely related allies are discussed. The geographical range of G. indonesiensis is greatly extended from the southwestern Pacific to the western Indian Ocean, the identification being supported by both morphological and molecular data. Slight range extensions are also reported for G. lowryi and G. speciosa.
