Description
Trichogramma distinctum Zucchi, 1988
Diagnosis. Flagelliform setae moderately short, with apex tapering abruptly; dorsal lamina with slight basal constriction and concave laterally; intervolsellar process distinct, not extending to apex of volsellae.
Comments. Trichogramma distinctum is similar to T. galloi and T. jalmirezi, more closely resembling the former. It differs from T. galloi in having the intervolsellar process not extending to the apex of the volsellae and the dorsal lamina with a wider posterior extension than in T. galloi. The most conspicuous difference separating T. distinctum from T. jalmirezi is the marked constriction in the dorsal lamina of the latter. Trichogramma galloi and T. distinctum also differ biologically, as T. distinctum requires higher temperatures than T. galloi when these parasitoids are reared on factitious hosts under laboratory conditions (Parra et al. 1991). Only the type material is known.
