Taxonomia de Brachycyrtus Kriechbaumer, 1880 (Hymenoptera: Ichneumonidae: Brachycyrtinae) do Brasil

Abstract

Brachycyrtinae (Hymenoptera: Ichneumonidae) is a small group of Darwin's wasps currently represented by only one genus, Brachycyrtus Kriechbaumer with 25 valid species for the world, nine of these species recorded in Brazil. A taxonomic study of the Brazilian fauna of Brachycyrtus (Ichneumonidae, Brachycyrtinae) was conducted based on material deposited in zoological collections. The specimens were identified and illustrated. 185 specimens belonging to 12 species were examined, including two new species. Brachycyrtus obelix Gauld & Ward was recorded for the first time in Brazil. The species B. convergens Cushman, B. cosmetus (Walkley), B. oculatus Cushman, B. pretiosus Cushman, B. veriatrix Gauld & Ward, B. walkleyae Gauld & Ward, and B. zani Gauld & Ward were also extended. In addition, morphological characters, a new proposal for diagnosis of the Brazilian species and digital images, an illustrated dichotomous identification key, and maps with geographic records for all species present in Brazil were added.
