Large populations of Tigriopus are reported from the Kerguelen Islands and Crozet Islands in the South Indian Ocean. The two populations exhibit complete sexual isolation, strong genetic differentiation and different karyological patterns. The description of these two new species points out only very slight morphological differences and they may be considered as sibling species. Distribution and status of the nine species of Tigriopus actually known are discussed.
