Abstract
The dung beetle tribes Deltochilini and Phanaeini (Coleoptera: Scarabaeidae: Scarabaeinae) play an important ecological role in the habitats in which they live. Despite much field work on these beetles in the Neotropical region, biological information on many taxa is still unknown. Here we provide information on species of Deltochilini and Phanaeini including temporal distribution of adults, sex ratio (Male : Female) and measurements of the individuals as well as on ecology and general biology of all species sampled in introduced (pasturelands of Brachiaria spp.) and native (patch of the Brazilian savanna) ecosystems of Brazil. Furthermore, our findings may help to understand the complexity of the effects of mixed ecosystems on the biodiversity of dung beetles.
