Platytyphlops corolliferus ( Gamô, 1984) n. comb.

Paralamprops corollifera Gamô, 1984: 21–25 , fig. 1–2.

Type material. Holotype: NSMT, subadult male. East of Japan Trench, 38°33.9–35.5’N, 145°15.1–15.7’ E. Not seen.

Diagnosis. Carapace without lateral ridges, marginal carina dentate, faint ridge present on pseudorostrum; eyelobe without lenses or tumidities. Antennule article 1 not expanded; accessory flagellum 0.6 main flagellum. Telson shorter than uropod peduncles, with 3 terminal setae, terminal setae equal. Uropod endopod article 1 equal to length of articles 2 and 3 together. Adult male unknown.

Depth. 5349–5368 m.

Distribution. East of Japan Trench, 38°33.9’–35.5’N, 145°15.1–15.7’E.

Remarks. Only the subadult male holotype is known. The most similar species is Platytyphlops carpusserratus . The two species can be distinguished by the teeth of the marginal carina. In P. corolliferus the teeth decrease in size posteriorly, while in P. carpusserratus the teeth are equal in size throughout the carina.
