Platymaia wyvillethomsoni Miers, 1886

( Fig. 5F )

Material examined. RV Hakuhō Maru KH-72-1 cruise, sta. 28 (Timor Sea; 09°34.4′S, 128°06.0′E – 09°33.5′S, 128°03.4′E, 295–296 m depth); 3 m beam trawl; June 24, 1972; 1 ovig.♀ (NSMT-Cr 29264: CB 39.5 mm excluding branchial spines, CL 36.7 mm excluding pseudorostral spines).

Remarks. A large ovigerous female ( Fig. 5F ) at hand is almost the same size as the holotype of Platymaia wyvillethomsoni , and agrees well with the descriptions and illustrations by Guinot and Richer de Forges (1985) and Griffin and Tranter (1986a). There is little doubt about the identification as P. wyvillethomsoni , which Guinot and Richer de Forges (1985) removed from the synonymy of P. remifera Rathbun, 1916 versus Griffin (1976).

Distribution. Japan to Australia through the Philippines, Indonesia, the Timor Sea and the Kermadec Islands; 189–549 m depth. Farrelly and Ahyong (2019) recorded this species, with photographs, from the Great Australian Bight, 189–426 m depth.
