[Taxacom] "Family" Tetrapterygidae

Hi Tony,

      I think that this is a typical case of splitters vs. lumpers, especially lumpers who cannot tolerate paraphyletic genera.  There seems to be no controversy about the two species of Anthropoides being sister taxa.

       However, there are indications that a genus Anthropoides could render genus Grus paraphyletic.  Therefore, those who cannot tolerate paraphyly can either resort to extreme splitting or just lumping them all in genus Grus.  In this case, they have chosen lumping.  Meanwhile, those who aren't bothered by paraphyly, have taken a middle ground approach between lumping and extreme splitting (splitting off Tetrapteryx as a separate monotypic genus from Anthropoides).

Dear Ken.

I am no expert on cranes (at all...) but the type species of Tetrapteryx, T. capensis, seems to be the blue crane of southern Africa which is variously given either as Grus paradisea e.g. in Avibase http://avibase.bsc-eoc.org/species.jsp?lang=EN&avibaseid=361AC2690622329F and Wikipedia https://en.wikipedia.org/wiki/Blue_crane, or as Anthropoides paradiseus in the IUCN Red List http://www.iucnredlist.org/details/22692109/0%20Anthropoides%20paradiseus and in the present Catalogue of Life ex ITIS https://www.itis.gov/servlet/SingleRpt/SingleRpt?search_topic=TSN&search_value=707817#null (also in Wikipedia under

Blue crane - Wikipedia<https://en.wikipedia.org/wiki/Blue_crane>
The blue crane (Grus paradisea), also known as the Stanley crane and the paradise crane, is the national bird of South Africa. The species is listed as Vulnerable by ...

Anthropoides as well, see https://en.wikipedia.org/wiki/Anthropoides). Nevertherless "Tetrapteryx paradisea" does seem to persist in some sources (e.g. try a Google scholar search) so I would be interested in the arguments for placing the species in question into either

Anthropoides - Wikipedia<https://en.wikipedia.org/wiki/Anthropoides>
Anthropoides is a small genus of cranes. It contains just two species: Blue crane, Anthropoides paradiseus, resident in southern Africa; Demoiselle crane ...

Tetrapteryx, Grus or Anthropoides at this time. Any further information from more expert persons than myself would be appreciated!

Hi all,
       I just learned that Family Tetrapterygidae was proposed by Chatterjee (2015) in the 2nd Edition of The Rise of Birds.  And it even has its own Wikipedia page:    https://en.wikipedia.org/wiki/Tetrapterygidae .
       The trouble is there is apparently no genus Tetrapteryx in this family.  The genus Tetrapteryx was proposed about 200 years ago for a genus of cranes.  Should we just ignore such a breach of nomenclatural rules or should it be formally suppressed before more people start using in classifications (as in the Wikipedia article).
