A new species of the deep-sea caridean genus Glyphocrangon A. Milne-Edwards, 1880, G. obtusis n.sp., is described and illustrated on the basis of the material collected in the South China Sea off the Pratas Island. It appears close to G. hakuhoae Takeda & Hanamura, 1994 and G. robusta Komai, 2004 among the 93 described species in Glyphocrangon. From G. hakuhoae, the new species is distinguished by the rostrum with less developed convexity on the dorsolateral margin and lacking transverse septa, and the less elevated median carinae on the pleomeres 1-5. From G. robusta, the new species differs in lacking transverse septa at the rosixtun. the fourth canna on the carapace with the two anterior parts unaligned and the posterior part divided into four lobes. Molecular genetic analysis using the barcoding segment of the mitochondrial COI gene supports the establishment of the new species.
