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

WA Museum Records and Supplements | Updated 1 years ago

ABSTRACT Three new species of lucinid bivalves are described from Australia. Two of these are assigned to the genus Callucina, previously known living only from the Western Atlantic Ocean. In Western Australia, Callucina linnaei ran'ges from the Houtman Abrolhos Islands northwards to the Dampier Archipelago. Callucina brittoni is recorded from islands on the Great Barrier Reef, Queensland. Another Indian Ocean species, C. winckworthi (Viader 1951) is recognized from Mauritius. The third new species, Pseudolucinisca wami, was previously confounded with the South and Western Australian endemic species, P. lacteola. Pseudolucinisca wami Wililii is distributed from Geographe Bay to Port Hedland while the more southerly range of P. lacteola extends from western Victoria to Cape Leeuwin, Western Australia. Revised descriptions are given for the genera Callucina and Pseudolucinisca. Callucina species have a fossil history in the Cenozoic of Europe and North America and the living Australian and Mauritian species may be relicts from a wider distribution in the Cenozoic Tethyan Ocean.
