摘要：
Ctenomys minutus Nehring, 1887 inhabits fields and pastures of the coastal plains of Santa Catarina (SC) and Rio Grande do Sul (RS), southern Brazil. This species shows territoriality, low vagility, and sedentary behavior. The sexr atio is unbalanced; there are more females both in the general (1.3∶1) and in the adult population (1.26∶1). The population was sexually dimorphic, with males being significantly larger than females in all measured in dividuals. Analysis indicated allometric form of variation in both sexes.
