 Remarks. The material examined agrees with the holotype male from New Caledonia (Baba 1990). However, we have observed a few specimens without epigastric spines (or very minute), as well as a few specimens with one minute parahepatic spine on each side. These specimens agree very well with the typical specimens in other diagnostic respects, and therefore, we regard that these differences represent intraspecific variation.   
 The genetic divergences of COI between G. squamea and all other species are usually larger than 15.0%. The smallest divergence of the same gene is observed in G. sanctae (6.3%) from New Caledonia and Vanuatu (Tab. 3)   
 Distribution. New Caledonia, 7– 180 m.
