1. A new genus and species of mole has been described from Tibet. The location is near the main road from Lhasa to Yunnan, but you need a special permit to get there. The description is not up to ICZN standards because the authors mentioned the name, Alpiscaptulus medogensis, in the abstract, which is specifically (and very inconveniently) prohibited.
2. There is a new proposal to split Gulf of Mexico population of Bryde’s whale into a new species. The paper is not on sci-hub yet so I don’t know how good the evidence is; from the abstract it looks like the authors only compared whales from different parts of the Atlantic.
3. A new bat, Myotis nimbaensis, described from Mt. Nimba; it looks very similar to M. welwitschii.
4. There is a new paper (Ojeda et al., Zoologica Scripta) on species limits in Phyllotis xanthopygius group, proposing but not describing two new species. I have the PDF if anybody wants it.
5. A 2020 paper I never mentioned here: a proposal to split meadow vole into three species: W, E and Florida. Western (M. drummondii) and eastern (M. pennsylvanicus s. str.) are very widespread and easy to see, but M. dukecampbelli is extremely rare and localized. In 2010 I spent a whole week in Lower Suwannie NWR where it occurs while studying alligators, and managed to see it only once. Might be a bit easier with a thermal scope.
6. Speaking of Florida splits, there was a 2010 dissertation proposing to split the Florida subspecies of least shrew as Cryptotis floridanus (actually, it’s a bit more complicated; the two forms are largely sympatric). It was never properly published or followed up, but is now beginning to make its way into checklists, so have a look.
7. An interesting paper on the systematics of some Himalayan Myotine bats, lumping a few taxa.
