«Genus MIRAPECTEN. new genus
Shell small, thin, strongly winged, with a number of elevated radiating ridges on the central disk, which bear hollow spines. Hollow spined ridges are also present on the wings. Hinge line finely transversely denticulated. Resilial pit triangular and deep.
Type: Mirapecten thaanumi, new species.
The group here designated comprises a small number of Pacific species, both recent and fossil, which are so markedly distinct in sculpture from any of the others that we feel a group name for them is merited. The Philippine Pecten mirificus Reeve belongs here.»

«Mirapecten Dall, Bartsch & Rehder, 1938
Mirapecten Dall, Bartsch & Rehder, 1938: 84, pl. 21, figs 7–8. Type species (by original designation): Mirapecten thaanumi Dall, Bartsch & Rehder, 1938 (= Pecten mirificus Reeve, 1853); Recent, off south coast of Molokai, Hawaii, in 70–99 fathoms [128–181 m].
Somalipecten Waller, 1986: 41. Type species (by original designation): Somalipecten cranmerorum Waller, 1986; Recent, off Somalia. Diagnosis. Medium-sized Decatopectinini with from 5–7 evenly spaced primary squamous plicae to 7–11 unevenly spaced primary and secondary plicae, squamous on most specimens, noduliferous or smooth on others; valves flattened, subcircular to circular, right valve slightly more convex than left, inequivalve, inequilateral to equilateral, auricles unequal in size; microsculpture of closely spaced commarginal lamellae; internal rib carinae present. Hinge with prominent dorsal teeth and weak resilial teeth, intermediate teeth lacking; byssal notch moderately deep, byssal fasciole rather narrow, ctenolium well-developed.
Distribution. Miocene–Recent (Hayami, 1989: 16). Tropical Indo-West Pacific, living in the littoral to sublittoral zones amongst coral or coral rubble on soft sediment.
Discussion. Hertlein (1969: N366) treated Mirapecten as a subgenus of Semipallium [Jousseaume] Lamy, 1928 and placed it in the suprageneric group of Decatopecten. Waller (1986: 40), followed by Vaught (1989: 119), considered Mirapecten to be a full genus in the tribe Decatopectinini. For comparison with Somalipecten Waller, 1986, see Dijkstra & Kilburn (2001: 283).»
