Remarks — This species is probably very common in WIO although rarely reported. It has been recently collected in the Mozambique channel at Europa and Juan de Nova (Poupin et al., 2013b; Poupin, 2016) and Réunion (Legall & Poupin, 2018). In Huenia grandidierii there is a strong sexual dimorphism of the shape carapace (as often seen in Huenia species) and the live coloration observed for Réunion is bright green (cf. photos in Legall & Poupin, 2018). Huenia grandidierii is very similar to Huenia pacifica Miers, 1879 reported from Indonesia to Fiji, French Polynesia and Easter Island. Griffin & Tranter (1986: 84) indicate a few differences between these two species, once suggested as possible synonyms.
Geographic and depth ranges — WIO, Somalia, Tanzania to Mayotte (this work), Réunion; intertidal to subtidal.
