Neogene Pectinidae (Bivalvia) of tribe Chlamydini in Patagonia (Argentina): Zygochlamys and three new genera
Zygochlamys Ihering, 1907 is revised and three new genera of tribe Chlamydini are named: the monospecific early Miocene genera Pixiechlamys new genus (type species: Pecten quemadensis Ihering, 1897) and Chokekenia n. gen. (type species: Zygochlamys nicolasi Morra, 1985), and the late Miocene-early P...
