Annachlamys Iredale, 1939 View in CoL

Annachlamys Iredale, 1939: 358 View in CoL . Type species (by original designation): Pecten leopardus Reeve, 1853 View in CoL (= Pecten flabellatus Lamarck, 1819 View in CoL ); Recent, western, northern and eastern Australia.

Diagnosis. Pectinini with a sturdy, subcircular shell, up to c. 60 mm high and a few specimens up to> 100 mm wide, with almost equally inflated valves, wider than high in late ontogeny, with numerous radial plicae (12–30), prominent widely spaced commarginal lamellae on disc and auricles of most adults (closely spaced in early ontogeny), auricles of most specimens without radial sculpture, internal rib carinae prominent. Hinge teeth weak. Byssal notch shallow; ctenolium obsolete or lacking in adult stage.

Distribution. Miocene–Recent (Beu & Darragh, 2001). Eurasia (Tethyan) (Hertlein, 1969), tropical western and southwestern Pacific, living in the littoral to sublittoral zones on soft sediment.

Discussion. Hertlein (1969: N355) treated Annachlamys as a subgenus of Chlamys , placed in the Chlamys group. Waller (1986: 40) considered Annachlamys to be a valid genus and placed it in tribe Decatopectinini . Following reconsideration of its phylogeny, Waller (2006a: 27, fig. 1.3) transferred Annachlamys to tribe Pectinini (as redefined by him, including Pecten and Gigantopecten ) because of its change from close-set to far-set commarginal lamellae during ontogeny, and because it is most similar morphologically to Gigantopecten , a genus of Pectinini occurring in European Cenozoic rocks. The position of Annachlamys has varied
