- Australia, New Guinea, parts of Indonesia and throughout most of South America
Heya @user:Stho002, ok you have check's on the following: Batrachemys – Wollumbinia – †Birlimarr – †Bonapartemys – †Lomalatachelys – †Prochelidella – †Palaeophrynops – †Parahydraspis – †Linderochelys – †Yaminuechelys
Ok Batrachemys has been synonymised with Mesoclemmys; Wollumbinia we will have to agree to disagree, most lit and checklists use Myuchelys though; Birlimarr (Megirian and Murray, 1999) valid genus related to Elseya member of Chelodininae; Bonapartemys, Lomalatachelys, Prochelidella, Palaeophrynops, Linderochelys all valid and members of the Chelinae; Parahydraspis synonymised with Phrynops geoffroanus by Gaperini et al., 1985 I am currently examining this type, it is definitely Phrynops but I will probably resurrect the species, but not done yet; Yaminuechelys valid genus member of the Hydromedusinae. I have all the refs if you need them. cheers, Faendalimas (talk) 03:47, 6 June 2014 (UTC)
With recent contact I decided to take a look at this group as it is my specialty as a taxonomist. I wanted to see what errors there were. Although Wiki has a be bold view on making changes when there is a possibility I could have an issue with NPOV I would rather be more precautionary. So going to list some mistakes here first. Calling this to the attention of Dan Koehl in paricular.
Three are currently recognised and were initially put up in recent years by Georges et al 1998, after many reviews of this the last by Guillon et al, 2010, the subfamilies were finally accepted. However, Georges et al and later myself in Georges and Thomson, 2010, did overlook the fact that names that would be available as subfamilies were originally proposed by Baur, 1893. These were Chelinae for the south American side necks (you have it as Chelidinae), Chelodininae for the Australian side necks, and Hydromedusinae for the south American snake necks. The first one needs to be changed to recognise original formation by Baur, 1893.
Batrachemys has been synonymised with Mesoclemmys, and although this may change in the future, it is currently considered a single genus, eg IUCN TTWG Checklist (2014)
Myuchelys vs 'Wollombinia, I acknowledge I am in a difficult position here I described Myuchelys. However most literature, actually all of it, uses Myuchelys having accepted that Wollombinia is not published. For example the 2012 and 2014 editions of the IUCN checklist.
In the above comment I made a year ago I commented on the various fossil taxa that have no pages. Including that Parahydraspis paranaensis was synonymised with Phrynops geoffroanus by Gasparini et al, 1996.
The pages listed under the subgenera, disagree with the included genera on the family page.
