Differential diagnosis. Bracon (Bracon) salviae sp. n. is related to B. (B.) exhilarator Nees, 1834.
The two species are separated by the combination of the following characters:
1 (2) Mesosoma approximately 1.6 times longer than height; propodeum, first and second metasomal tergites sculptured, 2-SR 2 times as long as m-cu, body 3.8 mm ............................................... Bracon (Bracon) salviae sp. n.
1 (2) Mesosoma 2 times as long as its height; propodeum and first metasomal tergite smooth; second metasomal tergite rugose, folds longituninal; 2-SR 1.4 times as long as m-cu, body 2.3–3.6 mm ..................... Bracon (Bracon) exhilarator Nees.
