Notes on Bolivian mammals. 4, The genus Ctenomys (Rodentia, Ctenomyidae) in the eastern lowlands. American Museum novitates ; no. 2891

Abstract

"Tuco tucos (genus Ctenomys) of lowland eastern Bolivia are reviewed. Synonymies, references, lists of all known specimens and localities, and new data on morphology and karyology are given for the four species (C. steinbachi, C. minutus, C. conoveri, and C. boliviensis) present. Ctenomys boliviensis displays some morphological variation and considerable karyological variation between localities. Diploid chromosome numbers of Ctenomys in lowland Bolivia range from 10 to 48"--P.[1].
