Trichogramma rojasi Nagaraja & Nagarkatti, 1973

Diagnosis. Hind wings with 12 to 15 setae in setae row, extending to apex; genital capsule dark; posterior extension of dorsal lamina tapering to pointed apex; ventral ridge short, extending nearly to middle of genital capsule; ventral processes very close to base of intervolsellar process.

Comments. Trichogramma rojasi can be confused with T. lasallei . However, these species can be separated by the following characters: posterior row of setae of the hind wing reaches the apex of the wing in T. rojasi (and does not in T. lasallei ); the ventral ridge is more evident and can reach the middle of the genital capsule in T. rojasi (the ventral ridge is smaller and the anterior limit is not clear in T. lasallei ); the ventral processes are very close at the base of the intervolsellar process in T. rojasi (these processes are very far from each other in T. lasallei ). Both species were characterized by molecular techniques ( T. lasallei GenBank ID AF282237.1/ AY182762 ; T. rojasi ID GenBank AF282239.1) ( Ciociola et al. 2001).
