The Zoochat Photographic Guide to Rodents: part two

The species of Microtus which are not depicted in the Zoochat galleries are listed alphabetically below. Several of the following are likely to be species complexes, and others may be treated as subspecies by some authors, so do not take the list as a definite total.

I've got shots of Social Vole - will check if they are halfway decent for you :) if mine aren't good enough, those taken by @ShonenJake13 or @ThylacineAlive might be.
 
Dichrostonychini (collared lemmings) is the second Tribe from Arvicolinae. It contains eight species in the single genus Dichrostonyx. Unsurprisingly, the IUCN notes that "Dicrostonyx taxonomy is complex and not well resolved."


None of the species are depicted here.


Northern Collared Lemming Dicrostonyx groenlandicus
Ungava Collared Lemming Dicrostonyx hudsonius
Nelson's Collared Lemming Dicrostonyx nelsoni
Ogilvie Mountains Collared Lemming Dicrostonyx nunatakensis (formerly treated as a subspecies of Dicrostonyx groenlandicus)
Richardson's Collared Lemming Dicrostonyx richardsoni
Arctic Lemming Dicrostonyx torquatus
Unalaska Collared Lemming Dicrostonyx unalascensis
Wrangel Lemming Dicrostonyx vinogradovi
 
Ellobiusini (mole voles) is the third Tribe from Arvicolinae. It contains five species in the single genus Ellobius.


One species is depicted here, albeit only as a museum specimen.


Northern Mole Vole Ellobius talpinus
Generally four subspecies are used (rufescens, talpinus, tanaiticus, transcaspiae) but up to eight have been described.

Lagurini (steppe lemmings) is the fourth Tribe from Arvicolinae. It contains three species in two genera: Eolagurus, Lagurus.


Two species, representing both genera, are represented in the Zoochat galleries.

The second species in the genus is Przewalski's Steppe Lemming Eolagurus przewalskii which is not depicted here. It is sometimes treated as a subspecies of Eolagurus luteus.

Lagurus
One species

The Sagebrush Vole Lemmiscus curtatus (of the Tribe Arvicolini) has also formerly been placed in Lagurus.

Lemmini ("true" lemmings) is the fifth Tribe from Arvicolinae. It contains eight species in three genera: Lemmus, Myopus, Synaptomys.

Two species from two genera are depicted here: Lemmus, Synaptomys.


........................................................


Lemmus
Five species, one of which is represented in the Zoocat galleries.


North American Brown Lemming Lemmus trimucronatus
Nine subspecies: alascensis, chrysogaster, harroldi, helvolus, minusculus, nigripes, subarcticus, trimucronatus, yukonensis. The subspecies nigripes from St George Island has been elevated to full species by some authors, although this is not generally followed. The eastern Siberian subspecies chrysogaster has also been treated as a full species.

Myodini (Asian voles) is the sixth Tribe from Arvicolinae. It contains about 36 species in five genera: Alticola, Caryomys, Eothenomys, Hyperacrius, Myodes.

Five species from two genera are depicted here: Alticola, Myodes.


........................................................


Alticola
Twelve species, one of which is represented in the Zoochat galleries.

There are three subgenera: Platycranius (for A. strelzowi); Aschizomys (for A. lemminus, A. macrotis, A. olchonensis); and Alticola (for the other eight species). The taxonomy of the genus has always been the matter of debate, with the subgenus Alticola ranging anywhere from one lumped species (A. roylei) to the eight recognised here.

Myodes
Twelve species, four of which are represented in the Zoochat galleries.


Southern Red-back Vole Myodes gapperi
As many as 29 subspecies have been described, but as always seems to be the case amongst the Myomorpha rodents, there is a lot of confliction and confusion around the forms. This may also be a species-complex.

Pliomyini (Balkan Snow Vole) is the ninth Tribe from Arvicolinae. It contains just one species, which is depicted below.

Note: the generic name of the sole living species Dinaromys bogdanovi does not match the name of the Tribe (Pliomyini) because, although the Tribe is currently monotypic, the fossil genus Pliomys was described prior to the discovery of the living species.


Balkan Snow Vole Dinaromys bogdanovi
Eight subspecies: bogdanovi, coeruleus, grebenscikovi, korabensis, longipedis, marakovici, preniensis, trebevicensis

Cricetus
One species


Common Hamster Cricetus cricetus
About ten subspecies have been in use, especially in Russia and Kazhakstan multiple subspecies have been described, but it looks like they are mostly treated as synonyms now which is suspect given the species' wide range. The three (former) European subspecies (canescens, cricetus, nehringi) are now generally merged into one (cricetus).

Also known as the European Hamster or Black-bellied Hamster.

The other two species in the genus are the Campbell's Dwarf Hamster Phodopus campbelli and the Djungarian Dwarf Hamster Phodopus sungorus (also known as the Russian, Siberian, or Striped Dwarf Hamster). These two species are extremely similar in appearance and both also have a lot of domestic colourations which really complicates identification of photographs. I've put three photos below but I don't know if they are titled correctly. There are a few more photos in the Zoochat galleries but these are the best ones.
