Coralichlamys Iredale, 1939

Coralichlamys Iredale, 1939: 355 . Type species (by original designation): Coralichlamys acroporicola Iredale, 1939 (= Pecten madreporarum G. B. Sowerby II, 1842 ); Recent, Australia.

Diagnosis. Small, coral-dwelling Pedini , irregularly shaped, with numerous unevenly spaced radial riblets; auricles highly unequal, posterior declined; antimarginal microsculpture in early ontogeny, secondary commarginal sculpture on anterior auricles and in late ontogeny; with prominent resilial and dorsal teeth; byssal notch deep, ctenolium well-developed.

Distribution. Miocene–Recent (Hayami, 1989: 15). In our opinion, Chlamys rutteni (Martyn, 1914) , from the Eocene of Java, Indonesia, does not belong in Coralichlamys . Indo-West Pacific, living in the subtidal to shallow sublittoral zones, lodged amongst Acropora branches.

Discussion. Hertlein (1969: N355) treated Coralichlamys as a junior synonym of Chlamys Röding, 1798 in the Chlamys group. Currently Coralichlamys is regarded as a monotypic genus in Chlamydini (i.e., Pedini ) ( Waller, 1993: 203). In some recent phylogenies ( Sherratt et al., 2016; Serb, 2016), specimens identified as Coralichlamys madreporarum (G. B. Sowerby II, 1842) are located in up to three distinct areas of the phylogram, indicating that the material consists of several unrelated taxa. Resolution of this question is beyond the scope of the present review.
