What is it about?

Based on specimens collected in the southeastern Andes of Ecuador, at Parque Nacional Sangay, but also including animals from mammal collections, a revision of the species of the group “cinereus” of the cricetid genus Thomasomys Coues, 1884 (Sigmodontini, Thomasomyini) was made.

Why is it important?

As a result, concomitantly to a new phylogeny based on a molecular marker (Cytb), a new species is recognized and described.

Perspectives

With the reported finding, the richness of Thomasomys in Ecuador increases to 15 species and rivals that registered in Colombia. Finally, we pose the necessity to join efforts in order to produce a significant advance in the knowledge of this complex genus of Andean sigmodontines.
