A new species of the deep-water shrimp genus Glyphocrangon A. Milne-Edwards, 1881, G. arduus n. sp., is described from the Austral Islands, French Polynesia. It is the first representative of Glyphocrangonidae known from French Polynesia. The closest morphological affinities of G. arduus n. sp. are with G. speciosa Komai, 2004 from New Caledonia and G. ferox Komai, 2004 from Madagascar. The new species is readily distinguished from G. speciosa by the weak armament of the posterior third carina on the carapace, different shape of the intercarinal tubercles on the carapace and pleon, and the living coloration. From G. ferox, G. arduus n. sp. is separable by the presence of an acute anterior tooth of the posterior fourth carina on the carapace, sharp intercarinal tubercles on the branchial region and the smaller corneas.
