This is a repost under the “Taxonomy” tag.
I realize not many many agree with me on this, but in regards to northern leopard frogs, bullfrogs, wood frogs, etc here in North America, I see many people using Lithobates. Lithobates was proposed by Hillis and Wilcox (2005) for certain central and south American frogs, and then Frost et al (2006) placed the aforementioned North American species into Lithobates. Subsequently, some (but not all) organizations referred to Lithobates pipiens, etc, rather than their former Rana designation.
The most recent paper on Rana/Lithobates, put pipiens, catesbeianus, clamitans, etc, back into Rana. I also note that many other papers, subsequent to Frost’s paper, rejected the use of Lithobates (e.g. Pauly et al. 2009). I also note that, up to and including this current year, Rana is still more commonly used than Lithobates.
From Yuan, et al. 2016:
" The major well-differentiated, morphologically and ecologically distinct clades within New World Rana largely support the traditional subgeneric designations for the genus… …Based on our phylogenetic analyses and the lack of any diagnostic morphological characters for the putative genera recognized by Fei et al. 2012 or Frost et al. (2006), and the clear monophyly of the larger group, we retain all these species in the traditional genus Rana."
I am suggesting that we switch these species back to Rana for INaturalist.
