A New Species of Aleiodes Wesmael (Braconidae, Rogadinae) with Potential for Biological Control of Spodoptera spp. (Lepidoptera, Noctuidae), and Notes on the Definition of the gastritor, circumscriptus, and Related Species-Groups.

A new species of Aleiodes Wesmael in the gastritor Thunberg species-group is described and illustrated. The new species, Aleiodes ceres Shimbori sp.n., occurs in Southern Brazil and Argentina. It is a potential biological control agent of caterpillars in the genus Spodoptera Guenée, namely S. cosmioides (Walker), S. eridania (Stoll), and S. frugiperda (J.E. Smith), which are serious pests on major crops including maize and soybean. The position of the new species within Aleiodes is discussed in relation to existing proposals of subdivisions of the genus into species-groups. In agreement with recent publications, the gastritor species-group is treated as separate from the circumscriptus Nees/bicolor Spinola group, as evidence suggests the latter is absent in the New World. We also propose the provisional shakirae Shimbori & Shaw species-group, to accommodate a clade of Neotropical species with geometrid hosts and morphological features similar to the gastritor and circumscriptus groups. A key to Neotropical species in the gastritor group and similar species is provided, except for species recently named without a morphological description.

The Apanteles adelinamoralesae species group (Hymenoptera, Braconidae) from Brazil, with descriptions of three new species reared from fruit borers(Lepidoptera, Depressariidae).

With more than 633 species, Apanteles is the largest genus within the subfamily Microgastrinae (Hymenoptera, Braconidae). We describe three new species reared from pests of commercial fruits, Apanteles ahuacatl Shimbori, Giacomelli & Fernández-Triana sp. n., A. aratiku Shimbori sp. n., and A. mayochinchipe Shimbori sp. n. They parasitize caterpillars in the subfamily Stenomatinae (Depressariidae): the soursop moth Cerconota anonella (Sepp), in fruits of sweetsop (Annona squamosa L.) and atemoya (Annona squamosa x Annona cherimola Mill.) (Annonaceae), the avocado borer Stenoma catenifer Walsingham, in fruits of avocado (Persea americana Mill.) (Lauraceae), and the cacao shoot borer Stenoma decora Zeller, in fruits and shoots of cacao (Theobroma cacao L.) (Malvaceae). The new Apanteles species are included in an expanded version of the key provided by Fernández-Triana et al. (2014) for the Apanteles adelinamoralesae species group. In addition, the previous record of Apanteles stenomae Muesebeck in Brazil is revised and considered to actually represent the species A. yolandarojasae Fernández-Triana.

First record of Cotesia scotti () (Hymenoptera: Braconidae: Microgastrinae) comb. nov. parasitising Spodoptera cosmioides (Walk, 1858) and Spodoptera eridania (Stoll, 1782) (Lepidoptera: Noctuidae) in Brazil

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.
