Antennule article 1 not expanded; accessory flagellum 1.0 main flagellum. Pereopod 5 reduced, all articles past basis subequal. Telson shorter than uropod peduncles, with 3 terminal setae, central seta longest. Uropod endopod broken. Adult male carapace with same pattern of ridges as in female. Antennule with cluster of aesthetascs on first article of main flagellum. Pereopod 5 larger than in female, but all articles past basis subequal. Depth. 369–1394 m . Distribution . South Africa , 34°25–48’S, 17°45’– 18°03’E . Remarks . Platytyphlops peringueyi is most similar to P. grimaldii , but can be differentiated from P. grimaldii and all other sculptured Platytyphlops by the pair of posterior dorsal ridges being short and produced as a blunt tooth. In all other Platytyphlops with many ridges on the carapace, the margin of the ridge in the posterior dorsal (sub median) position is entire or wavy, not produced as a tooth.
