Taxonomia das vespas-de-darwin labena cresson, 1864 (Hymenoptera: Ichneumonidae: Labeninae) do Brasil

Abstract

Labeninae (Hymenoptera: Ichneumonidae) belongs to a group of Darwin's wasps, which includes 12 genera, four tribes and 164 valid species. Labena Cresson, 1864 has 46 valid species for the world, with tropical distribution, and until now, only five species were registered for Brazil. The present taxonomic study was carried out based on material from several national zoological collections, in which the species were identified and photographed. A total of 191 specimens belonging to 12 species were obtained, two of them new species: Labena sp. 1 and Labena sp. 2. With that, the number of species registered for the country increased from five to 16 species. Furthermore, the genus was recorded for the first time in the states of Amazonas, Pará, Roraima, Rondônia, Amapá, Maranhão, Minas Gerais, Rio de Janeiro and São Paulo. Labena guanacasteca Gauld, 2000, Labena humida Gauld, 2000, Labena iquitosica Sääksjärvi, Bordera & González-Moreno, 2010, Labena lachryma Gauld, 2000, Labena littoralis González-Moreno, Bordera and Sääksjärvi, 2015, Labena morda Gauld, 2000, Labena pluvia Gauld, 2000 Labena polemica Gauld, 2000, Labena zerita Gauld, 2000, are recorded for the first time for Brazil. Therefore, the addition of new information together with the proposed identification key and the additions to the species descriptions will allow the identification of the species registered for Brazil and will provide support for the development of future work with Labena.
