A list of aquatic and semiaquatic Heteroptera from a collecting trip to Pitinga, a village in a mining area in the County of Presidente Figueiredo in the Central Amazon is presented. Identified were fifty five species of Heteroptera, distributed in 13 families. Among the insects collected, some are new records for this Amazonian region and in addition 3 apparently undescribed species of Microvelia and one of Paravelia remain for further study.KEYWORDS: Aquatic Heteroptera, Gerromorpha, Nepomorpha, New state records Heterópteros (Insecta) aquáticos e semi-aquáticos de Pitinga, Amazonas, Brasil RESUMO Uma lista de heterópteros aquáticos e semi-aquáticos coletados durante uma viagem a Pitinga, uma área de mineração no município de Presidente Figueiredo, na Amazônia Central, é apresentada. Foram coletadas 55 espécies de Heteroptera, distribuídas em 13 famílias. Entre os insetos coletados, alguns são registros novos para essa região amazônica.
RESUMOEste é o primeiro registro de Paravelia recens (Drake & Harris, 1935) (Heteroptera: Veliidae) em fitotelmata de Guzmania brasiliensis Ule, 1907 (Bromeliaceae) (t-test between season; t=2,57; p=0,011), and the abundance of individuals was positively correlated with water volume by bromeliad (r s = 0,18; p=0,033). This fact could be explained by the major input of water in the wet season, causing the increase of mean water volume by bromeliad.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
