Distribution. Previously known from Sibuyan Sea, Davao Gulf off Southeastern Mindanao, Ternate, Moluccas, Sulu Archipelago, Indonesia, Southwestern Australia; 37– 100 m. Now also known from South China Sea; 6.7– 79 m. The present record extends the bathymetric range of the species from 37–100 to 6.7– 100 m

Remarks. The specimens agree essentially with the description of Galathea consobrina De Man, 1902 , with the exceptions of features of the Mxp3 merus: most of the specimens examined have two stout spines on the extensor margin, but the male of MBM215139 has a very small spine between the two stout spines. Three hepatic spines are consistently present in most of the specimens examined, as in the holotype, but one male (MBM 215213) has five spines. This is the first record for the species from the Chinese waters.
