The Zoochat Photographic Guide to Rodents: part two

A couple of new species have been added to the thread, both of which are in the same photo by @BeardsleyZooFan



Bushveld Gerbil and Red Veld Rat - ZooChat


On the left is a Bushveld Gerbil Gerbilliscus leucogaster (on page 6 of this thread), and on the right is a Red Rock Rat Aethomys chrysophilus (on page 7 of this thread). Both are also new genera for the thread.

 

Another new photo (and new genus) for the thread, with an African Climbing Mouse Dendromus sp. by @Giant Eland - the exact species isn't clear (D. nyikae is suggested) but I have included it because it is one of the few represented species in the family Nesomyidae (African and Madagascan rats), of which only six species of c.70 species are depicted here.

Another new species (and genus) added to the thread, with Bush Karoo Rat Myotomys unisulcatus by @Giant Eland in this post (#130): The Zoochat Photographic Guide to Rodents: part two

It's been four months since the last photo of a "new" species was added into this thread, but now @lintworm has uploaded a couple of photos of a White-tailed Antsangy Brachytarsomys albicauda from Wroclaw Zoo. I used both photos in the thread because even though one wasn't properly focused it does show the entire tail. The family Nesomyidae is on page two of this thread (this species makes seven depicted out of about seventy species total in that family).

 

It's been almost a year, but two more new species have been added to the Myomorpha thread; both photos are by @Najade

Romanian Hamster Mesocricetus newtoni - taking the family Cricetidae up to 37 pictured species (out of c.700 species) - and Cape York Rat Rattus leucopus - taking the family Muridae up to 83 pictured species (out of c.810 species). Myomorpha as a whole is now at 146 pictured species ... out of c.1680 species. There is a little way to go yet!

Looks like a Brown Rat to me.

 

That's great. And that is also your first entry into the Rodent threads!

 

@Coelacanth18 has added a photo of a Western Harvest Mouse Reithrodontomys megalotis, which takes the number of Cricetidae depicted up to 38 species (out of c.700!).

In the thread here, on post #71 - The Zoochat Photographic Guide to Rodents: part two

 

Four new species have been added to the thread, from the extremely under-represented New World myomorphs. All photos are by @Giant Eland taken in the wild in Chile.

The number of rodents represented in this Part Two thread is now 152 species from 79 genera (out of a total of about 1680 species in about 346 genera, so not a great percentage of rats and mice being covered here). For the entire Rodentia combined there are 363 species from 162 genera represented in the Zoochat galleries (out of c.2400 species and c.500 genera).

 

@HOMIN96 has uploaded a new species for the rodent threads, with a Ural Field Mouse Apodemus uralensis at Plzen Zoo (the seventh species of that genus to be represented in the Zoochat galleries).

Three more species have been added to this thread, one being a photo of a live animal and two just being photos of old taxidermy specimens.


Best is the Northern Pigmy Mouse Baiomys taylori by @d1am0ndback

The other two photos are of Northern Mole Vole Ellobius talpinus and Montane Water Vole Arvicola scherman.

A couple more photos by @Najade have been added, of wild animals in Paraguay. Both species are the first representatives of their genera, and are also amongst the few representatives of the New World subfamily Sigmodontinae - there are about 400 species, of which these two species take the total of depicted species in the thread to nine.


They are on page 5 of the thread, in posts 81 and 87 respectively.

Another new addition from @Najade - also from the subfamily Sigmodontinae as in the above post - the Chaco Leaf-eared Mouse Graomys chacoensis.


Chaco Leaf-eared Mouse (Graomys chacoensis) - ZooChat


The genus Graomys is probably a larger complex than the four species which are normally recognised currently (G. centralis, G. domorum, G. edithae, G. griseoflavus). Four further described species are usually treated as synonyms of G. griseoflavus (namely G. cachinus, G. chacoensis, G. lockwoodi, and G. medius) although these are, at least in part, probably valid species. In this thread I have followed the status quo and only listed the first four as valid, with a note on the others as being possibles, hence the photo above is placed under G. griseoflavus.

 

A couple more photos by @Najade of Paraguayan rodents from the Cricetidae subfamily Sigmodontinae have been added to the gallery and are new species for this thread.

A photo of a museum specimen of Meadow Jumping Mouse Zapus hudsonius by @Pleistohorse has been added to the thread, in this post (#6) on the first page: The Zoochat Photographic Guide to Rodents: part two

The jumping mice are related to jerboas (family Dipodidae) - in this thread I am retaining them as a subfamily but they may also be split into two full families as Zapodidae (jumping mice and birch mice) and Dipodidae (jerboas).

Bavarian Pine Vole Microtus bavaricus by @remar at Alpine Zoo Innsbruck in Austria:

Added into post #38 here The Zoochat Photographic Guide to Rodents: part two

This is the seventh Microtus species depicted in the thread, taking the number of Cricetidae up to 51 (out of c.700 species).
