Material examined. South China Sea. Nansha Islands: MBM 150210, 1 male (5.3 mm), Dongmenjiao, CN SSFJ 3-13, 1– 3 m, coral reef, 20 May 1990; MBM 150235, 1 female (3.9 mm), Da’aijiao, CN SSFJ 6-36, 1– 3 m, coral, 25 May 1990. Xisha Islands: MBM 150316, 1 ovigerous female (4.7 mm), Beijiao, coral reef, CN 58C-029, 23 Mar.1958.

Distribution. Previously known from Amami-oshima, Okinawa, Taiwan, Obi Major, Christmas Island, Ambon; intertidal. Now also known from South China Sea; 1– 3 m.

Remarks. The specimens agree with the previous descriptions of the species with the rostrum being uniquely truncate, as long as broad, and armed with four teeth on each side. In the holotype, the carapace bears six epigastric spines and lacks postcervical spines. In the specimens of Miyake & Baba (1966) two epigastric spines and two postcervical spines are present. In the specimens of Baba (1977), two to four epigastric spines and two postcervical spines are present. The carapaces of our specimens have six epigastric spines and two postcervical spines. This is the first record for the species from the Chinese waters.
