Morphological and cytogenetics comparison in species of the Mendocinus-group (genus Ctenomys) with emphasis in C. Australis and C. Flamarioni (Rodentia-Ctenomyidae)

Asample of 208 specimens from Ctenomys mendocinus-group species (106 females and 102 males) was studied. Five species were included in a comparative cytogenetic and morphometric analysis: Ctenomys flamarioni (N=59), colected between Torres and Estação Ecológica do Taim from Brazil, and. Ctenomys aus...
