Notes on Bolivian mammals. 3, A revised diagnosis of Andalgalomys (Rodentia, Muridae) and the description of a new subspecies. American Museum novitates ; no. 2890

Abstract

"Reported characters of the phyllotine genus Andalgalomys are reviewed and a revised diagnosis is presented. Andalgalomys is phenetically more similar to Graomys than to Calomys or Eligmodontia. A new subspecies of Andalgalomys pearsoni is described from Bolivia. This, the first Bolivian record for the genus, extends the known range northward approximately 300 km. Karyotypes for both subspecies of A. pearsoni are: A. p. pearsoni has 78 chromosomes and A. p. n. ssp. 76. These are the highest reported diploid numbers for phyllotine rodents. The first specimens from Bolivia of Thrichomys apereoides and Ctenomys minutus are documented"--P. [1].
