| Popis: | The scope and species content of the pterioid bivalve Monotis Bronn with almost global distribution in Norian (Late Triassic) marine strata are reconsidered. Various infra-generic groupings have been proposed in the last 50 years and all have been subject to some criticism. A scheme which allocates all species to one of eight subgenera (Monotis, Entomonotis Marwick, Eomonotis Grant-Mackie, Inflatomonotis Grant-Mackie, Maorimonotis Grant-Mackie, Pacimonotis Grant-Mackie & Silberling, Baikalomonotis Bychkov and Praemonotis Bychkov) is favoured here and, in line with current trends, these eight are afforded generic status. There is also a growing move away from recognition of subspecies and, when applied here, allows most to be accepted at species level with a few names synonymised. |
