A revision of the Australian species of Notoacmea, Collisella and Patelloida (Mollusca : Gastropoda : Acmaeidae)

Abstract

The Australian species of Notoacmea, Collisella and Patelloida are revised on the basis of shell and radular characters. Six species are recognised in Notoacmea, two in Collisella and 12, together with two subspecies of an Indian Ocean species, in Patelloida. The majority of the species are found in temperate Australia, there being only 6 taxa recognised from tropical Australia. Patelloida septiformis Quoy & Gaimard, 1834 and P. elongata Quoy Gaimard, 1834 are both rejected from the Australian fauna.
