 Remarks. Galathea coralliophilus Baba & Oh, 1990 is close to G. corallicola Haswell, 1882 and G. ohshimai Miyake & Baba, 1967, in having two epigastric spines on the carapace, epipods present on the P1, and no extensor spine on the Mxp3 carpus. In addition to the differences noted by Macpherson (2008), G. coralliophilus can be distinguished from G. corallicola and G. ohshimai by the presence of both the scale-like ridges behind the anterior second transverse ridge and the feathered setae on the carapace and abdomen. Galathea coralliophilus is also distinguished from G. ohshimai by the Mxp3 merus that bears the distal flexor spine subequal to, instead of smaller than, the proximal flexor spine.   
The specimens agree quite well with the original description and illustrations of Baba & Oh (1990). This is the first record for the species from the Chinese waters.
