ABSTRACT
ABSTRACT This is the first report of Cotesia scotti (Valerio and Whitfield) comb. nov. in Brazil, attacking larvae of the black armyworm, Spodoptera cosmioides, and the southern armyworm, S. eridania. The moth larvae were found respectively, infesting a protected cropping of organic tomato in Hidrolândia, Goiás, Brazil, and a transgenic soybean crop in São José dos Pinhais, Paraná, Brazil. Biological, molecular and morphological characters were used to confirm the identity of the specimens. Parasitoid identification presented a challenge since the species has most diagnostic characters of the genus Cotesia Cameron, but few in the poorly defined genus Parapanteles Ashmead. Based on morphological and molecular evidence, we transfer Parapanteles scotti to the genus Cotesia. The new combination is discussed by comparison with morphologically similar species and available molecular data.
ABSTRACT
Hymenoepimecis neotropica (Brues & Richardson) (Hymenoptera, Ichneumonidae, Pimplinae) parasitoid of Araneus omnicolor (Keyserling) (Araneae, Araneidae): first host record and new occurrence to Brazil. The species of the genus Hymenoepimecis occur only in Neotropical region, being recognized for using as their hosts spiders which build orbicular webs. That wasp was described occurring only in the Guyana. This work expands the geographical distribution of the species to Brazil and records the spider Araneus omnicolor (Araneae, Araneidae) as its host. Furthermore, it provides information about the natural history of this interaction.

Espécies do gênero Hymenoepimecis ocorrem somente na região Neotropical, sendo reconhecidas por utilizarem, como hospedeiras, aranhas que constroem teias orbiculares. Essa vespa foi descrita ocorrendo somente na Guiana. Este trabalho amplia a distribuição geográfica da espécie para o Brasil e registra a aranha Araneus omnicolor (Araneae, Araneidae) como sua hospedeira. Além disso, fornece informações sobre a história natural desta interação.
