The present work aimed to study the morphology, taxonomy and bionomy of Ablabesmya Johannsen, 1905 (Diptera, Chironomidae, Tanypodinae) species of the State of São Paulo. This genus of world distribution prise 69 species, of which ten are registered in the Neotropical region, however none specifically mentioned for Brazil. The analyzed material derives from three lotic systems (streams and rivers) and seven lentic systems (reservoirs and lakes), which are located in three cities of the State of São Paulo (São Carlos, Luís Antônio and Brotas). The sampling followed the conventional methods of benthonic studies. The larvae were kept alive in the laboratory to obtain the associations between larva, pupa and adult. The identification of the species was based on the original descriptions. The results allowed the identification of eight species, seven of wich are new species and the second record of Ablabesmyia metica Roback (1983) for the Neotropical region and the first one to Brazil, describes the immature stages, unknown before. The new species are described with the respective diagnoses. The ecologic information on the genus are discussed and perspectives for the future studies are mencioned.
