A revision of the Australian Condylocardiinae (Bivalvia : Carditoidea : Condylocardiidae)

Abstract

Nineteen species belong to the Condylocardiinae in Australia, eighteen of these are endemic. Six genera are recognised: Benthocardiella Powell with two new species, B. burtonae n. sp. and B. darwinensis n. sp.;Condylocardia Bernard with five species, one new (C. cometa n. sp.); Condylocuna Iredale with four species, three new (C. annieae n. sp., C. jimbecki n. sp., and C. tricosa n. sp.); Cunanax Iredale with four species; Isodontocardia n. gen. is monotypic, with one new species (I. microcardia n. sp.); and Austrocardiellan. gen. with three species, one new (A. pouli n. sp.).

Each species is illustrated and described from shell characters. Descriptions include full synonymy, subsequent references and habitat and distribution data. All type material relating to this revision is illustrated. The gross anatomy of Condylocardia notoaustralis Cotton is described.

Three species have been excluded fromCondylocardia and the subfamily Condylocardiinae: Condylocardia chapmani is transferred to Puyseguria, ?Neoleptonidae; Condylocardia ovata is transferred to Mysella, Galeommatidae sensu lato; and Condylocuna minuta is transferred to Cuninae.
