SALGADO-NETO, Geraldo; FERNANDEZ-TRIANA, José L.; TAVARES, Wagner de Souza  e  ZANUNCIO, José Cola. Diolcogaster flammeus sp. nov. from Brazil, a new Microgastrinae wasp (Hymenoptera: Braconidae) of importance in biological control. Rev. Bras. entomol. [online]. 2018, vol.62, n.3, pp.232-236. ISSN 0085-5626.  http://dx.doi.org/10.1016/j.rbe.2018.06.001.

A new species of Diolcogaster (Ashmead, 1900) (Hymenoptera: Braconidae) is described and illustrated. Additionally, a key to all New World species formally published of the xanthaspis species-group (to which the new species belongs) is provided. The solitary larval parasitoid Diolcogaster flammeus sp. nov. was collected in Viçosa, Minas Gerais State, Brazil. This natural enemy was reared from caterpillars of Agaraea minuta (Schaus, 1892) (Lepidoptera: Erebidae) feeding on plants of spiked spiralflag ginger, Costus spicatus (Jacq.) Sw. and ginger spiral, Costus spiralis (Jacq.) Roscoe var. spiralis (Costaceae). The fauna of the xanthaspis group in the New World included just three published species prior to this publication. Diolcogaster flammeus sp. nov. is the only yellow-orange species of the xanthaspis group recorded in the New World thus far.
