Decatopectinini Waller, 1986

Diagnosis. Pectininae with very closely spaced commarginal lamellae, delicate antimarginal microsculpture restricted to the pre-radial growth stage, absent from auricles and sides of disc; dentition with dorsal and/or intermediate teeth, the latter multiple or absent in some taxa, resilial teeth weak or absent. Internal plicae carinate or with carinate edges of internal plicae near ventral margin.

Discussion. Waller (1986: 40) introduced a new tribe Decatopectinini with Decatopecten Sowerby II, 1839 as the type genus and included the following genera: Anguipecten Dall, Bartsch & Rehder, 1938 , Annachlamys Iredale, 1939 , Bractechlamys Iredale, 1939 , Excellichlamys Iredale, 1939 , Flexopecten Sacco, 1897 , Gloripallium Iredale, 1939 , Juxtamusium Iredale, 1939 , Mirapecten Dall, Bartsch & Rehder, 1938 , and Somalipecten Waller, 1986 . Dijkstra (1991) later included a new genus Glorichlamys, Dijkstra & Kilburn (2001: 283) synonymized Somalipecten Waller, 1986 with Mirapecten Dall, Bartsch & Rehder, 1938 , and Waller (2006a: 27, fig. 1.3) transferred Annachlamys to tribe Pectinini and Flexopecten to tribe Aequipectinini . Waller (2011) added the new genus Antillipecten Waller, 2011 and transferred Nodipecten Dall, 1898 from Pectinini to Decatopectinini , although the latest molecular phylogeny by Serb (2016) included Nodipecten in Amusiini .As noted in the introduction, despite varying positions in recent molecular phylogenies, we retain Annachlamys in Pectinini here.
