Galathea genkai Miyake & Baba, 1964 

Galathea genkai Miyake & Baba, 1964: 208  , figs 3, 4 (coast of northern Kyushu, 10 m).— Lewinsohn, 1969: 120, fig. 23 (Red Sea, 20–35 m).— Haig, 1974: 447 (Western Australia).— Baba, 1988: 74 (Sibuyan Sea, Philippines, 68 m).— Davie, 2002: 61 (no record).—Baba et al., 2008: 69 (compilation).— Baba et al., 2009: 111, figs. 90–91 ( Taiwan).— Poore et al., 2011: 332, pl. 10 G (color photo, Taiwan).

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).

Madagascar. ATIMO VATAE, Stn CP3520, 24° 51.2 'S, 47 ° 28.2 'E, 80–86 m, 30 April 2010: 1 M 5.4 mm (MNHN-IU- 2013-8433).—Stn DW3532, 24° 39.4 'S, 47 ° 31.7 'E, 86–87 m, 2 May 2010: 1 F 5.5 mm (MNHN-IU- 2013-8432).—Stn DW3605, 24° 54.5 'S, 44 °51.0'E, 56–57 m, 13 May 2010: 1 ov. F 5.5 mm (MNHN-IU- 2013- 8435).—Stn DW3606, 25° 48.4 'S, 44 ° 51.1 'E, 44–46 m, 13 May 2010: 1 ov. F 5.6 mm (MNHN-IU- 2013-8431).

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.
