Polietina Schnabl & Dziedzicki, 1911 has been placed in different subfamilies mainly based on chaetotaxy and general morphology of adults. This genus has most recently been placed in Reinwardtiinae on the basis of larval characters. The male terminalia, however, indicates that Polietina is phylogenetically close to the basal group of Muscinae. By the analysis of all available type material, the genus and nine species are redescribed: P. bicolor Albuquerque; P. distincta Couri & Lopes; P. flavithorax (Stein); P. major Albuquerque; P. minor Albuquerque; P. orbitalis (Stein); P. rubella (Wulp); P. steini (Enderlein) and P. concinna (Wulp) which is revalided and lectotype designated. Neotypes are proposed to Polietina flavithorax and to Polietina orbitalis. Polietina wulpi is proposed as a new species. A key is also presented.
