A Review of the Relegamoria molleri Species Complex (Gastropoda Volutoidea: Volutidae) from Eastern Australia

A review of the Relegamoria molleri (Iredale, 1936) complex was undertaken using newly sourced material from a number of private research collections and Atlas of Living Australia (“ALA”) database, which contains the Australian and Queensland Museums holdings and records. After a detailed review of several hundred specimens including morphological and distributional characters, Relegamoria Iredale, 1936 is reinstated at the generic level and the two previously recognised subspecies R. molleri isabelae Bail, Limpus & Poppe, 2001 and R. molleri vandenbergae Bail, Limpus & Poppe, 2001 are raised to full species and a further nine new species are recognised: Relegamoria aliuamolleri new species, Relegamoria archaeomolleri new species, Relegamoria ariae new species, Relegamoria elsieae new species, Relegamoria charlyi new species, Relegamoria barbaracollinsae new species, Relegamoria annetteae new species, Relegamoria youngorum new species and Relegamoria ashleyfieldi new species. This revision highlights the need for a broader review into the deep-water fauna of Queensland and New South Wales, particularly as more private collections are made available for scientific study.
