The hemerobiids are considered an important agents for pest control and are excellent predators as adults larvae stages of aphids, coccids and eggs of Lepidoptera. The alimentary habit, the buccal apparatus type and longevity of various months accentuate the quality of these predators. The taxonomic knowledge of these is extremely important to the establishment of the species, a fundamental stage to an wide spectrum of biological studies, including biological control. In Brazil, the taxonomic studies on this group are scarce and the reports on the presence of hemerobiids species in agroecosystems are rare. The objective of this study was to characterize the species of hemerobiids associated with the citrus, coffee, cotton, maize, mate, sorghum and soybean crops. The specimens examined were collected in the munici- pal districts of Jaboticabal, Nuporanga, Ribeirão Preto and Santa Rosa de Viterbo (SP), Lavras (MG), Cascavel and São Mateus do Sul (PR). The collections were realized during the harvest of 1999/2000 and 2000/2001, by Moericke, suspended traps and entomological net. The characterization of the species was realized mainly by the study of the wing veins and male terminalia. The principal structures were illustrated and scanned by electronic microscope. The four species registered belong to the two subfamilies (Hemerobius bolivari Banks, 1910, H. domingensis Banks, 1941 and H. gaitoi Monserrat, 1996) and (Nusalala tessellata Gerstaecker, 1888).
