The Zoochat Photographic Guide to Rodents: part one

A couple of new species have now been added into the thread.


Firstly, Brazilian Squirrel Sciurus aestuans with two photos by @Therabu (due to the taxonomic confusion in South American squirrels I am retaining S. aestuans and S. brasiliensis as a single species for now; S. ingrami is a junior synonym of S. brasiliensis).

Secondly, and more excitingly, an anomalure! The first member of this family for the thread. Lord Derby's Anomalure Anomalurus derbianus by @Giant Eland.

Family Ctenomyidae - tuco-tucos

About sixty-five species in a single genus, Ctenomys


There are no photographs in the Zoochat galleries, and they are barely even mentioned in text posts. Zootierliste has only three listings for European collections: C. magellanicus at Berlin Zoo (1914-1916), C. mendocinus at London Zoo (1915, and 1972-1974), and C. talarum at London Zoo (1967-1970).


I don't imagine there will be photos of any live Ctenomys species added to the Zoochat galleries, although possibly a museum specimen or two may appear.

Ohh @Chlidonias the more that you doubt photos will ever be added, the more sweet it is when I do :D Two species now!
 
As per the above post, two species of Tuco-tucos now added on post #226 here: The Zoochat Photographic Guide to Rodents: part one

The number of rodents represented in this Part One thread is now 211 species from 83 genera (out of about 740 species and about 158 genera - so over a quarter of the total species and over half of the genera are now represented by Zoochat photos).

Coendou
About fifteen species currently recognised. There is a certain amount of dispute over whether certain taxa are species/subspecies/synonyms.

There are five species represented in the Zoochat galleries, with one of them only depicted as a museum specimen.


Taxonomic note: this genus may also be split into three (Coendou, Echinoprocta, Sphiggurus). In this case the Stump-tailed Porcupine Coendou rufescens would be placed in Echinoprocta (as a monotypic genus); the genus Sphiggurus would contain the species ichillus, insidiosus, melanurus, mexicanus (including laenatus), pruinosus, roosmalenorum, spinosus (including villosus), and vestitus; and the genus Coendou would contain the species baturitensis, bicolor, nycthemera, prehensilis (including sanctamartae), quichua (including rothschildi), and speratus.
