Revision of the recent Australian Turridae referred to the Genera Splendrillia and Austrodrillia

Abstract

Turrids previously referred to the genera Splendrillia and Austrodrillia from southern Australian waters are revised; two tropical representatives are included. Sixteen species are recognized in Splendrillia and five in Austrodrillia. Clavus candidulus Hedley, 1922 is transferred to Splendrillia. Five new species of Splendrillia are described, three from southern Western Australia and two from Queensland. In Splendrillia, S. molleri Laseron, 1954 is synonymized with S. woodsi (Beddome, 1883) and S. harpularia (Desmoulins, 1842) and S. duplaris Hedley, 1922 are provisionally transferred to the genus Crassispira in the subfamily Crassispirinae, and a new species is described in this genus. Based on an examination of the radula of the type species, Austrodrillia angasi (Crosse, 1863), the genus Austrodrillia is also transferred to the Crassispirinae. In Austrodrillia, A. achatina (Verco, 1909) is synonymized with A. dimidiata (Sowerby, 1896).
