Remarks: morphological and morphometric characters and all measurements of our specimens fit well measurements in numerous descriptions and redescriptions available in the literature, especially those of Blommers (1976) for specimens from Madagascar. Mentioned only from South­East Asia and Madagascar, it is the second mention in the Indian Ocean of this species outside Madagascar after Mayotte Island (Kreiter et al. 2020a).
