Coverage

The only species of the family known from NSW is Choriplax grayi:

 

Choriplax grayi (H. Adams & Angas, 1864).

This is a small (up to 30 mm), rare species with reduced valves in a large fleshy girdle. It lives on a red alga to a depth of 20 m or occasionally on sponges on brown algae or on stones, in southern Australia from NSW to Perth, WA, including Tas. The only NSW specimen known is the holotype, dredged from Watsons Bay, Port Jackson before 1867. As no  further specimen has been collected in NSW in the intervening 150 years, its continuing presence in NSW is regarded as doubtful.

The species is illustrated in The Southern Synthesis p. 180, Fig. 3.33.
