Genital capsule broad; volsellae swollen, with accentuated lateral constriction; tubular ventral processes joined to intervolsellar process, dorsal ridge undeveloped (dorsal view) on midline of genital capsule; dorsal lamina short, with no distinct posterior extension. Comments . This species is similar to T. acacioi , as both species have a similar genital-capsule shape; in T. atopovirilia , the volsellae are strongly constricted apically and have tubular ventral processes. According to Zucchi & Monteiro (1977) , T. caiaposi Brun, Moraes & Soares is a junior synonym of T. atopovirilia . Type repository . National Museum of Natural History, Washington, D.C. (holotype and paratypes). Type locality . Sololá, Guatemala. Distribution in South America. Argentina, Brazil, Colombia and Venezuela. Hosts . This species has been recorded from seven different hosts, mostly lepidopterans of economic importance ( Zucchi et al . 2010 ). It was first reared from parasitized Vanessa sp. eggs ( Lepidoptera : Nymphalidae ) on a species of Malvaceae from Guatemala. It was recorded on Helicoverpa zea and Spodoptera frugiperda in corn fields in Brazil ( Zucchi & Monteiro 1994 ). Trichogramma atopovirilia has also been reared on factitious hosts, for biological control of the fall armyworm Spodoptera frugiperda (J.E. Smith, 1797) ( Lepidoptera : Noctuidae ) ( Morales et al . 2004 ; Melo et al . 2007 ; Dias et al . 2010 ). In Brazil, Anagasta kuehniella (Zeller) and Corcyra cephalonica (Stainton) ( Lepidoptera : Pyralidae ) have been shown to be the most suitable factitious hosts for mass rearing ( Parra et al . 2015 ).
