Abstract

Edgbastonia alanwillsi n. gen. & n. sp. is restricted to a small group of springs on Edgbaston Station near Aramac in western Queensland where it is assumed to be relictual. It has close similarities in shell morphology to some species of Amnicolidae found in China and India and the female reproductive system has unique characters that separate it from any other described taxon attributed to the Hydrobiidae or any related family. Sequence data from COI, 16S and 18S indicate that this species is closely allied to taxa included in Jardinella Iredale & Whitley, 1938, the only genus of Hydrobiidae (sensu lato) that has been previously recognised as inhabiting the Queensland artesian discharge springs. However, several important morphological characters separate this taxon from species included in the possibly para- or polyphyletic Jardinella. Based on our molecular results, the Australasian 'hydrobiid' taxa fall within a distinct clade (Tateinae) within a broad concept of Hydrobiidae.
