Lupocyclus philippinensis Semper , in Nauck, 1880

( Fig. 11F )

Material examined. RV Hakuhō Maru KH-72-1 cruise, sta. 45, 1 Ə infested by a Sacculina (CB 20.5 mm including lateral teeth, CL 17.0 mm including frontal teeth), NSMT-Cr 30924.

Remarks. The female at hand ( Fig. 11F ), infested by a Sacculina parasite, lacks all the chelipeds and ambulatory legs, but the carapace agrees well with the excellent figures of Lupocyclus philippinensis Semper , in Nauck, 1880, given by Leene (1940), Sakai (1939, 1976), Crosnier (1962), and Osmani et al. (2019). This species is rather well known ( Ng et al., 2008).

Distribution. Widely distributed in the Indo-West Pacific from Japan to the western Indian Ocean through the East and Southeast Asia, and Australia; 25–130 m depth.
