Livonia mammilla (G. B. Sowerby I, 1844) [WoRMS]

| Abstract |
The Livonia mammilla ‘group’ (Gastropoda, Volutidae) is reviewed following examination of museum material of geographically disjunct (120–450 km separation distance) and conchologically distinct populations from southeastern Australia and deepwater off the Northeast Shelf and Central Eastern Shelf Transition Provinces of Queensland, Australia. The following four deepwater Queensland populations are herein recognised as new allopatric species, all having some, presumably close, relationship with L. mammilla (G.B.Sowerby I, 1844): Livonia mooloolaba sp. nov. from the Tweed-Moreton region, L. capricornia sp. nov. from the Capricorn–Swains Reef region, L. hydrographica sp. nov. from the Mackay–Hydrographer's Passage region, and L. pithensis sp. nov. from Innisfail–Pith Reef region. A key, diagnoses, descriptions, specimens examined, and figures are presented for each species. In addition, a neotype is designated for Livonia mammilla (G.B. Sowerby I, 1844) with a new diagnosis, re-description and figures. That species is here regarded as restricted to the waters off southeastern Australia. Livonia pithensis sp. nov. substantially expands the recorded range of Livonia into the Northeast Shelf of tropical Queensland making it comparable to the recorded latitudinal range of the genus on the North-West Shelf of tropical Western Australia. |
