Material examined. RV Hakuhō Maru KH-72-1 cruise, sta. 11 (Sulu Sea ; 08°12.7′N, 117°59.6′E – 08°11.8′N, 117°58.5′E; 285–306 m deep); 3 m beam trawl; 26 May, 1972; 1 ˁ ( CB 29.4 mm; CL 27.4 mm including rostral spine), 1˂ (ovig.) ( CB 37.1 mm; CL 35.6 mm), NSMTCr 28976; 1 ˂ ( Fig. 10F View Fig ) ( CB 31.6 mm; CL 28.7 mm), NSMT-Cr 28977 GoogleMaps .

RV Hakuhō Maru KH-72-1 cruise, sta. 12 (Sulu Sea ; 08°19.0′N, 118°09.1′E – 08°18.7′N, 118°08.5′E; 495–500 m deep); 3 m beam trawl; 26 May, 1972; 6 ˁˁ ( CB 9.2 mm; CL 8.4 mm – CB 21.8 mm; CL 20.1 mm), 6˂˂ ( CB 9.9 mm; CL 9.3 mm – CB 21.5 mm; CL 19.3 mm), NSMTCr 28992 GoogleMaps .

Remarks. The genus Platymaia is comprised of 10 species from Indo-West Pacific ( Griffin and Tranter, 1986; Ng et al., 2008). We have many specimens of various sizes (CB 9.2–37.1 mm), which agree well with the description by Guinot and Richer de Forges (1986).

Lee et al. (2017) recently recorded P. aff. remifera from the South China Sea, noting that the interior border of the branchial region is armed with three strong spines in the South China Sea specimens and five weak spines in the Taiwanese specimens. Based on our specimens, however, this character seems variable. There is one strong spine followed by one to four spines of variable distinctness.

Distribution. Philippines ( Guinot and Richer de Forges, 1986; this study), Taiwan ( Ng and Huang, 1997), and South China Sea ( Serène and Lohavanijaya, 1973); 100–700 m deep.
