Amusiini Thiele, 1934

[emend. Waller, 2006a]

Diagnosis. Pectininae with weak radial macrosculpture or smooth, internal rib carinae present, disc microsculpture of closely spaced commarginal lamellae, hinge teeth welldeveloped, consisting of resilial and dorsal teeth, intermediate teeth weak or lacking, auricular crura prominent.

Remarks. Waller (2006a: 22–27, fig. 1.3) separated the Amusium and Pecten groups into their own tribes for the first time because of phylogenetic separation. He considered that Amusium , Euvola Dall, 1898 and Leopecten Masuda, 1971 all evolved from Amussiopecten Sacco, 1897 (all included in Amusiini ), whereas Annachlamys Iredale, 1939 and Pecten evolved from Gigantopecten Rovereto, 1899 (all included in Pectinini ).

There has been continuing confusion over the relative priority of Macrochlamys Sacco, 1897 and Gigantopecten , but following Waller & Bongrain (2006), the International Commission on Zoological Nomenclature (2008) accepted that Macrochlamys Sacco, 1897 is a junior homonym of Macrochlamys Benson, 1832 , and adopted Gigantopecten as the valid name.

The tribe name has usually been attributed to Habe (1977), but Waller (2011: 93) attributed it to Thiele (1934: 805). Waller (2007, 2011) further discussed the evolution of weakly sculptured to smooth scallops resembling Pecten and Amusium , pointing out the complex origins of the living taxa, and adding the new genus Zamorapecten Waller, 2011 in Amusiini .
