Martens, 1894 exemplify one of the most enig-matic distributional patterns among limnic organisms in Australasia. These viviparous cerithioidean gastropods are endemic to the Torres Strait Islands, located on the Sahul shelf corridor between Australia and New Guinea. The occurrence of the two constituent species is highly restricted: P. supralirata (Smith, 1887) on Prince of Wales Island, and P. semoni Mar-tens, 1894 on Hammond Island. Long recognized erroneously as members of the heteroge-neous, polyphyletic and widespread Thiaridae, morphological and molecular data presented here reveal that the taxon has to be placed within Pachychilidae, a family otherwise absent from Australia. Comparison with other South East Asian pachychilids, in particular
