Resumo

Stoneflies (Plecoptera) are aquatic insects widely used in ecological and monitoring studies as indicators of environmental quality due to their high sensitivity to pollution. Among Brazilian Plecoptera, Perlidae is the most diverse family, with four genera (Anacroneuria Klapalek 1909, Enderleina Jewett 1960, Kempnyia Klapalek 1914, and Macrogynoplax Enderlein 1909) and about 150 species. Herein, based on data from the barcode region of the mitochondrial cytochrome c oxidase subunit I (COI) gene and morphological characters, we studied specimens of Enderleina and Macrogynoplax, mainly from the Brazilian Savanna. Our alignment with a total length of 608 base pairs included 23 COI sequences, of which 10 are new and 13 were obtained from GenBank. The sequences and congruence of the obtained species clusters were analyzed using neighbor joining. As a result, we describe a new species of Enderleina, the first of this genus in the Brazilian Savanna, and update the geographic distribution of some Macrogynoplax species. A new record was included for Macrogynoplax veneranda Froehlich 1984 in Sao Paulo state and the first record of M. yupanqui Stark 1996 in Brazil was also included. First records were made for Macrogynoplax matogrossensis Bispo and Neves 2005 and a Macrogynoplax specimen in Goias and Bahia states, respectively. Consequently, we expanded the distribution of the genus in the Brazilian Savanna and Atlantic Forest. In addition, we provide observations on the morphological differences found among these species, discuss about the distribution of the genera, present molecular data discussing their contributions to the knowledge of the genus, and comment on the recommendations for future research considering a scenario of integrative approaches. Lastly, we present a key to identify the adult males of Enderleina. (AU)
