Querino, Ranyse B. & Zucchi, Roberto A., 2019, Annotated checklist and illustrated key to the species of Trichogramma Westwood (Hymenoptera: Trichogrammatidae) from South America, Zootaxa 4656 (2), pp. 201-231 : 205

Trichogramma bellaunionense Basso & Pintureau, 2001

Diagnosis. Antenna with relatively long setae; base of dorsal lamina wide and with no notch laterally, dorsal lamina with pointed apex and not reaching volsellar apex; intervolsellar process triangular and moderately developed, not reaching dorsal lamina apex ( Basso & Pintureau 2001).

Comments. Trichogramma bellaunionense is most similar to T. lasallei Pinto, 1999 . According to Basso & Pintureau (2001), in T. bellaunionense the dorsal lamina has a pointed apex and no lateral notch, and in T. lasallei the dorsal lamina has the apex usually obscurely pointed, and two narrow notches at the base. It is very difficult to separate these species morphologically, thus T. bellaunionense was not included in the key.
