Thomasomys auricularis commonly known as the red Andean thomasomys[3] is a species of rodent in the genus Thomasomys found in the western Andes of southwestern Ecuador.
Although described in 1923 by Harold Elmer Anthony,[4] T. auricularis was treated as synonym or subspecies of Thomasomys pyrrhonotus until they were identified as a separate species in 2003 and officially recognized in Mammal Species of the World (2005).[5][6]
Description
Thomasomys auricularis is medium in size for its genus, with a head-body length of 138 to 155 millimetres (5.4 to 6.1 in). It is characterized by its relatively long tail, moderately long hindfoot, large skull, and large, inflated auditory bullae. Initially it was compared to the similar looking T. aureus and T. pyrrhonotus but has a few distinguishing characteristics. The skull is smaller than T. aureus. The tail is longer than T. pyrrhonotus. The auditory bullae is larger T. aureus but comparatively smaller than T. pyrrhonotus.[6]
