Callucina and Pseudolucinisca (Mollusca: Bivalvia: Lucinidae) from Australia: revision of genera and description of three new species

Abstract

Three new species of lucinid bivalves are described from Australia. Two of these are assigned to the genus Call1lcilia, previously known living only from the Western Atlantic Ocean. In Western Australia, Calli/cilia lililiaci ran'ges from the Houtman Abrolhos Islands northwards to the Dampier Archipelago. Calli/cilia briltolii is recorded from islands on the Great Barrier Reef, Queensland. Another Indian Ocean species, C wilickworl/ii (ViaderI951) is recognized from Mauritius. The third new species, I'sclldolllciliisCll Wililii, was previously confounded with the South and Western Australian endemic species, P. laclcola. Psci/doli/ciliisea Wililii is distributed from Geographe Bay to Port Hedland while the more southerly range of P /aclcola extends from western Victoria to Cape Leeuwin, Western Australia. Revised descriptions are given for the genera Calli/cilia and I'sclidoli/ciliisCll. Calli/cilia species have a fossil history in the Cenozoic of Europe and North America and the living Australian and Mauritian may be relicts from a wider distribution in the Cenozoic Tethyan Ocean.
