Abstract

Helicopsyche von Siebold, 1856 is divided into six subgenera, of which two occur in Brazil: H. (Cochliopsyche) with nine spp. and H. (Feropsyche) with 25 spp. Although the latter subgenus is the most species-rich in the country, only three species are known from the Brazilian Amazon. In this study, we describe and illustrate two new species for Central Amazonia, Brazil: Helicopsyche johansoni sp. nov. and Helicopsyche manaos sp. nov. based on the morphology of adult males. In addition, a map with the distribution of the species of this subgenus for the Brazilian Amazon is provided.
