Revision of the Neosarmatium meinerti species complex (Decapoda: Brachyura: Sesarmidae), with descriptions of three pseudocryptic Indo–West Pacific species

Ragionieri et al. (2009) provided genetic and morphometric evidence that the widespread Indo-West Pacifi c sesarmid crab Neosarmatium meinerti (De Man, 1887) is a species complex composed of four species. The four have discrete ranges: one along the African mainland; one from islands in the western Indian Ocean; one from southern and eastern Asia; and one from northern Australia. The present paper clarifies the taxonomy of the four species and describes three new taxa. An updated identif cation key of all extant members of the genus is provided.
