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
