Trichogramma bruni Nagaraja, 1983

Diagnosis. Flagelliform setae long; dorsal lamina with distinct basal constriction, extending about two-thirds of length of genital capsule; intervolsellar process short, not extending up base of volsellae.

Comments. The following combination of characters separates T. bruni from T. lasallei and T. rojasi : long flagelliform setae, basiconic sensilla in position 4, short anterior setae on scutellum, genital capsule yellowish, and long ventral ridge. According to Velásquez & Téran (2003), T. castrensis Velásquez & Téran is a junior synonym of T. bruni .

Type repository. Institute of Biological Sciences, Universidade Federal de Minas Gerais (UFMG) collection (holotype and paratypes); Natural History Museum, London and Commonwealth Institute of Biological Control, Indian Station, Bangalore (paratypes) (holotype examined).

Type locality. Belo Horizonte, MG, Brazil.

Distribution in South America. Argentina, Bolivia, Brazil, Chile, Venezuela.

Hosts. Associated with several lepidopteran hosts in agricultural (fruit orchards) and forest habitats ( Zucchi et al. 2010). Trichogramma bruni was recently reared from eggs of Heraclides astyalus (Godart, 1819) ( Lepidoptera : Papilionidae ) on Citrus sp. ( Rutaceae ) ( Querino et al. 2017). It is commonly found in areas with more stable plant cover, such as forests and fruit orchards. However, it has been collected in soybean areas in Argentina ( Valverde et al. 2009, 2014) and in Brazil ( Dudczak et al. 2017).
