Abstract
Hetaerina giselae sp. n. is described and illustrated based on specimens collected at Pico do Itambé State Park, Minas Gerais, Brazil. Integration of morphological and molecular data (COI) supports the recognition of the new species. The new species can be separated from its morphologically closest congeners, such as Hetaerina longipes Hagen in Selys, 1853, and Hetaerina westfalli Rácenis, 1968, by a combination of characters of the male anal appendages, female intersternite, and general anatomical features. In addition, we present the description of the larva, highlighting the main morphological differences that distinguish it from adults and other known larvae of the genus.
