Two new species and new records of the genus Nectopsyche Müller, 1879 (Trichoptera: Leptoceridae) from Pará state, Brazil

Abstract

The genus Nectopsyche is widely recognized by its striking adults, with colored setae and scales, even metallic and/or iridescent. It is primarily distributed in the Neotropical region, with a few species found in the Nearctics. Nectopsyche has more than 100 described species, with 26 of them recorded in Brazil. In Pará state, one of the largest Brazilian’ states, only three species have been recorded. In contribution to the taxonomic knowledge about the Neotropical caddisflies, especially those of the Amazonian region, we propose two new species of Nectopsyche from Pará state based on male specimens: Nectopsyche tridentata n. sp. and Nectopsyche froehlichi n. sp. In addition, Nectopsyche acutiloba, Nectopsyche adusta, Nectopsyche jenseni, and Nectopsyche quatuorguttata are recorded for the first time in the state of Pará. Our results increase the number of Nectopsyche species recorded in Brazil to 28, and the number of recorded species in the state of Pará to eight.
