Oxypleurodon sphenocarcinoides (Rathbun, 1916) (Fig. 3C–E) Material examined. RV Hakuhō Maru KH-72-1 cruise, sta. 54, 1 Ə (CB 5.1 mm excluding lateral plates, PCL 8.8 mm), 1 ovig.8 (6.7× 11.6 mm), NSMT-Cr 30912; 1 ovig.8 (7.8× 12.7 mm), NSMT-Cr 30913; 1 8 (5.0× 8.3 mm), NSMT-Cr 30914. Remarks. The specimens (Fig. 3C–E) examined agree well with the original description (Rathbun, 1916), and the accounts (Griffin, 1976; Richer de Forges and Ng, 2009). Oxypleurodon sphaenocarcinoides was already recorded from the Sulu Sea by Takeda et al. (2021) at a depth of 285– 306 m. Distribution. The Philippines and the South China Sea; 93–306 m depth. The present record of O. sphenocarcinoides is the first for the South China Sea, and the bathymetric record of 760– 777 m is the deepest for the species.
