Taxonomy. Ctenomys conoveri Osgood, 1946 View in CoL ,

“Colonia Fernheim, 16 km. west of Filadelfia, Paraguayan Chaco. Approximately Log. 60°10'W., Lat. 22°15’ S.,” Boqueron, Paraguay .

Ctenomys conoveri was initially considered a unique species and classified in the subgenus Chacomys . Nevertheless, data from electrophoresis did not support the subgenus, and it was considered as sister species to C. frater and C. lewisi . Ctenomys conover has been included in the Bolivian-Paraguayan group, but using molecular analysis, it belongs to the fraterspecies group. Karyotype is 2n = 48 in Bolivia and 2n = 50 with FN = 64 in Paraguay. Sperm morphology is simple asymmetric. Monotypic.

Distribution. S Bolivia (Santa Cruz, Chuquisaca, and Tarija departments) and NW Paraguay (Boqueron Department). View Figure
