Abstract Cercopidae is one of the largest families of the spittlebug superfamily Cercopoidea. Most spittlebugs species are characterized by bright color patterns. Thus, this study evaluated for the first time the Cercopidae species collected in rice crops, Novo Progresso, Pará state, Brazil. Insects were collected weekly between November/2010 and March/2011 from areas without (WA) and with agrochemical applications (AA). Four species were recorded: Deois incompleta (Walker, 1851) (71 specimens in WA area and 50 in AA area); Mahanarva spectabilis (Distant, 1909) (39 specimens in WA area and 39 in AA area); Mahanarava tristis (Fabricius, 1803) (26 specimens in WA area and 20 in AA area); Zulia pubescens (Fabricius, 1803) (11 specimens in WA area and four in AA area). The species collected displayed pronounced color polymorphism when compared with the color patterns of the same species from other regions. This makes correct identification more difficult for these species. Therefore, taxonomic and diagnostic informations provided in this study will help in the correct identification, control and monitoring of these insects in future studies. Besides that, we recommend monitoring in rice fields and further study of the biology and ecology of cercopids in Brazil to assess the potential of these species as rice pests.
