| Summary: | Platytyphlops mawsoni (Hale, 1937) n. comb. Hemilamprops mawsoni Hale, 1937: 44–46, figs 4a–b, 5a–l. Paralamprops mawsoni. — Băcescu 1988: 24.— Corbera 2000: 20–22, fig. 11.— Petrescu & Wittmann 2003: 588–591, figs 6, 221–254. Type material. Holotype: SAMA C2056, female. Off Enderby Land, Antarctica, 66°12’S, 49°37’E. Diagnosis. Carapace with 2 pairs of broad lateral ridges, marginal carina entire, ridge present on pseudorostrum; eyelobe with lenses or tumidities. Antennule article 1 not expanded; accessory flagellum 0.7 main flagellum. Telson shorter than uropod peduncles, with 3 terminal setae, terminal setae equal. Uropod endopod article 1 1.7 length of articles 2 and 3 together. Adult male carapace with 3 pairs of lateral ridges. Antennal peduncle articles 4 and 5 with setae around entire circumference of articles. Uropod endopod article 1 2.8 length of articles 2 and 3 together. Depth. 240–630 m. Distribution. Antarctic continental shelf, South Shetland Islands, Enderby, Weddell Sea, 66– 76°S, 11– 61°W. Remarks. An ample redescription of the species, including the adult male, was provided by Petrescu & Wittman (2003), in addition to the excellent original description in Hale (1937) and the additional description in Corbera (2000). The most similar species is P. latus, which can be differentiated by body size and the pseudorostrum. Platytyphlops latus has an excavate pseudorostrum in dorsal view, while P. mawsoni has an anteriorly projecting pointed pseudorostrum in dorsal view. In addition, P. latus (7 mm ovigerous female) is much smaller than P. mawsoni (21 mm subadult female).
