Microsciurus
Microsciurus or dwarf squirrels is a genus of squirrels from the tropical regions of Central and South America.
There are four recognized species, however, recent DNA analysis has shown that there is some confusion regarding the traditional classification of the Microsciurus species:
Genus Microsciurus - dwarf squirrels
Central American dwarf squirrel, Microsciurus alfari Allen, 1895, Costa Rica, Nicaragua, Panama, Northern Colombia
Amazon dwarf squirrel, Microsciurus flaviventer Gray, 1867, western Amazon basin
Western dwarf squirrel, Microsciurus mimulus Thomas, 1898, Ecuador, Colombia, Panama
Santander dwarf squirrel, Microsciurus santanderensis Hernández-Camacho, 1957, Central Colombia
With a head and body length of 15 centimetres (5.9 in) and a 12 centimetres (4.7 in) long tail, dwarf squirrels are not as small as their name suggests; they are hardly smaller than the common red or gray squirrels. The neotropical pygmy squirrel, not in this genus, is much smaller than these species. Microsciurus species have gray or brown backs, and white bellies.
