Remarks — Mayotte KUW specimens erroneously determined in the field as ‘Pilodius cf. flavus’. Re-examination in July/September 2011 have shown that they are in fact Eupilumnus calmani, based on description and drawings in Guinot (1960), including aspect of male G1/G2. Eupilumnus calmani is very similar to Eupilumnus actumnoides (A. Milne-Edwards, 1873) in western Pacific (Japan, Papua New Guinea, New Caledonia, Samoa, Kiribati, Australia) but it is different by the anterolateral spines on the carapace, sharp and long, instead of reduced in E. actumnoides, and by the presence of a stridulating apparatus on P2 merus and cheliped (illustrated in Guinot, 1960: 113, fig. 11) and presence of a row of granules on pterygostomian area.
Distribution — IWP, Red Sea, Tanzania to China Sea, French Polynesia; intertidal to 174 m. Distribution extended herein to French Polynesia from specimen collected in the Tuamotu (Mataiva) determined in Moorea CRIOBE collection in 2014 by J. Poupin.
