Coloration. Variable, from reddish to dark brown, sometimes with white spots and flecks on carapace and abdomen. P 1 with dark bands on distal part of merus, carpus and palm, tips of fingers white. P 2–4 with whitish and dark transverse bands; white band on distal part of merus and propodus. Miyake & Baba (1966) described a different color pattern: overall yellowish white, carapace yellowish gray.

Remarks. The morphological characters are quite constant in all specimens examined, although they came from various localities. However, we have observed a small genetic divergence between the specimens collected from Australia and Madagascar (<3.0%). The divergences with all other species are usually larger than 12.0% ( COI), although the smallest divergence is seen between G. paulayi  n. sp. (9.3 % COI) ( Tab. 1).

Distribution. Japan, Palau island, Mariana Islands, Taiwan, Philippines, Indonesia, Australia, Papua New Guinea, New Caledonia, western Indian Ocean, Maldives Islands, Chagos islands, Scattered Islands, Madagascar; 0–41 m, on Pocillopora  spp., rubble, algae  , hydroids, under rocks.
