Trichogramma pusillum Querino & Zucchi, 2003
Diagnosis. Genital capsule small; dorsal lamina with broad posterior extension; intervolsellar process extremely minute.
Comments. Trichogramma pusillum resembles T. bennetti, a Colombian species, but it differs by the short intervolsellar process, shorter flagelliform setae, unmodified volsellae, narrower genital capsule, and short ventral ridge with an indistinct anterior extremity. The most conspicuous character to distinguish them are the volsellae, which are distinctly lobate in T. bennetti . Trichogramma pusillum was collected in an electrical suction trap set in a forest reserve (Querino & Zucchi 2003a). Only the type material is known.
