An Asiatic Chironomid in Brazil: morphology, DNA barcode and bionomics.

In most freshwater ecosystems, aquatic insects are dominant in terms of diversity; however, there is a disproportionately low number of records of alien species when compared to other freshwater organisms. The Chironomidae is one aquatic insect family that includes some examples of alien species around the world. During a study on aquatic insects in Amazonas state (Brazil), we collected specimens of Chironomidae that are similar, at the morphological level, to Chironomuskiiensis Tokunaga and Chironomusstriatipennis Kieffer, both with distributions restricted to Asia.

A new species of Forcipomyia (Microhelea) Meigen (Insecta: Diptera: Ceratopogonidae) from the Neotropical region.

We describe and illustrate a new species of biting midge belonging to the subgenus Forcipomyia (Microhelea), from the Estação Biológica de Boracéia, São Paulo State, Brazil. We include illustrations of the mouthparts, head, thorax, legs, abdominal setae, and habitus. The new species is similar to the few other recorded Neotropical species of biting midges, such as Forcipomyia (Microhelea) alleni, Forcipomyia (Microhelea) castneri, Forcipomyia (Microhelea) grandcolasi, and Forcipomyia (Microhelea) tettigonaris.
