Popis: | Gripopterygidae is a diverse family of stoneflies, Plecoptera, distributed in the Southern Hemisphere. It has been traditionally divided into five subfamilies, but the monophyly of most of these is not supported by molecular the more comprehensive molecular analysis of the order. To test the monophyly of Antarctoperlinae, and to establish the phylogenetic position of a new Gripopterygidae species, we performed a morphological cladistic analysis including 38 morphological characters and 27 terminal taxa, with representatives of the four subfamilies present in South America and three Austroperlidae. Based on published information, we rooted the tree with Penturoperla barbata, Austroperlidae. As a result, Antarctoperlinae was recovered as polyphyletic, with Vesicaperla kuscheli and Plegoperla punctata, two members of the subfamily, placed outside the clade that includes the nine remaining genera of Antarctoperlinae. Vesicaperla also falls outside the family in previous molecular analysis. Based on this evidence, it should not be placed in Antarctoperlinae. Plegoperla punctata, known only from the type series, possesses many missing entries in our data matrix. Based on this, it seems convenient to maintain its subfamilial placement. In the tree obtained, the potential new species nests together with Pehuenioperla llaima. We thus accept it as a member of Pehuenioperla and describe it as P. microptera sp. nov Fil: Pessacq, Pablo.
