Material examined. South China Sea. Macclesfield Bank, Stn 24, 15°26'30"N, 114°14'E, 24–63 m, May 1892: 1 M 4.3 mm ( NHMUK).

Remarks. The species is characterized by the scale-like ridges on the carapace and the absence of epigastric spines. The molecular analyses have shown the existence of a complex of species morphologically differentiated by the shape of the rostrum and the length of the walking legs. We have found three different species: G. genkai Miyake & Baba, 1964 , G. gladiola n. sp. from Vanuatu, New Caledonia and Chesterfield Islands, and G. m a c h a e r a n. sp. from the Solomon, Wallis and Futuna Islands (see Remarks of G. machaera ).

Distribution. Japan, northern Kyushu, Philippines, Sibuyan Sea, Taiwan, South China Sea (Macclesfield Bank), Western Australia, Red Sea, Madagascar; 10– 87 m.
