Trichogramma galloi Zucchi, 1988

Diagnosis. Flagelliform setae short with apex tapering abruptly; basiconic sensilla sparse; dorsal lamina with narrow posterior extension generally extending beyond apex of volsellae; intervolsellar process long and distinct, almost at same level as apex of the volsellae; ventral ridge short, extending to middle of the genital capsule.

Comments. Trichogramma galloi most closely resembles T. distinctum and T. jalmirezi; however, it can be distinguished from these species by the following combination of characters: narrower posterior extension of the dorsal lamina, longer intervolsellar process, extending to the level of volsellae or just beyond. It is also separated from T. distinctum biologically since the thermal requirements are lower than T. distinctum, for both species reared on factitious hosts, under laboratory conditions (Parra et al. 1991). This species is reared massively for biological control of the sugarcane borer (Parra 2014).
