Bractechlamys Iredale, 1939 View in CoL

Bractechlamys Iredale, 1939: 366 View in CoL . Type species (by original designation): Bractechlamys evecta Iredale, 1939 View in CoL (= Pecten vexillum Reeve, 1853 View in CoL ). Recent, 0.5 ml SE of Lizard Island, QLD, 19 fathoms [35 m]; widespread in tropical western Pacific.

Diagnosis. Decatopectinini with 8–15 primary radial plicae, some species with nodules on plicae; with secondary radial riblets; shape oblong to subcircular; with prominent intermediate teeth, a relatively deep byssal notch, prominent costae on auricles, and an obsolete ctenolium.

Distribution. Recent. Tropical Indo-West Pacific and eastern Atlantic, living in the littoral to sublittoral zones amongst coral rubble on soft sediment.

Discussion. Grau (1959: 120) and subsequently Hertlein (1969: N366) treated Bractechlamys , together with Comptopallium Iredale, 1939 and Complicachlamys Iredale, 1939 , as junior synonyms of Semipallium Jousseaume in Lamy, 1928 in the Decatopecten group. Waller (1972a: 245) pointed out that Semipallium has reticulate (“shagreen”) microsculpture, lacking on Bractechlamys and its relatives, and belongs in tribe Pedini . At present Bractechlamys is treated as a valid genus, placed in Decatopectinini by Waller (1986: 40).
