( Fig. 7H)

Material examined. Off Kuwannon, Koror Is., Palau Is., dredged, with coralline algae; 1 ovig.♀ (cb 9.0×cl 6.3 mm), 1 ♀ (11.0× 7.8 mm), NSMTCr 30975; June 17, 1980, K. Baba leg.

Remarks. This species is characteristic in having the weakly convex four-lobed front, and the outer lobe being about twice the length of the inner lobe ( Fig. 7H). Of the five anterolateral teeth of the carapace, the first or the external orbital tooth is much larger than the following teeth, and the fourth tooth is smallest and almost obsolete ( Fig. 7H). The details of the carapace dorsal ridges are finely shown by Crosnier (1962), Takeda (1989a), and Wee and Ng (1995).

Distribution. The Pacific Ocean from Hawaii and Japan to Australia, and the Indian Ocean from the Andaman Sea to Madagascar, with 15–80 m in depth. New to the Palau Islands.
