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.
