摘要

Three new Brazilian species of Polana (Varpulana) are described and illustrated, based on males and females: P. (V.) agualimpa sp. nov., from Distrito Federal; P. (V.) feitosai sp. nov., from Piaui and P. (V.) recurva sp. nov. from Parana. An updated key to males of P. (Varpulana) is presented, the diagnosis of the subgenus is revised and a new state record is presented to P. (V.) pandara. Additionally, morphological differences found in the dorsal sculpturing of the first valvula between the species of Polana are reported.
