Chrysis binominata Mocsáry, 1889 is similar to Chrysis excavata Brullé, 1846 ( Figs 5A–C View FIGURE 5 ), but it can be distinguished by several characters including: the shape of the transverse frontal carina, which is broadly M-shaped in Chr. binominata ( Fig. 5D View FIGURE 5 ); the genal carina, where the distance between the ventral margin of the eye and the genal carina is twice as large in Chr. binominata ( Fig. 5E View FIGURE 5 ) compared to the same distance in Chr. excavata ( Fig. 5B View FIGURE 5 ); and the proximity of the black spots, which are closer together in Chr. binominata ( Fig. 5F View FIGURE 5 ) than in Chr. excavata ( Fig. 5C View FIGURE 5 ). Chrysis binominata Mocsáry, 1899 stat. resurr. is therefore considered a valid species. However, it is probable that Chr. excavata represents a species complex with multiple species synonyminzed by Kimsey & Bohart (1991) and therefore a reassessment of this group is needed. Specimens identified by Ducke and Linsenmaier as Chr. diana Mocsáry, 1889 and Chr. pleuretica Mocsáry, 1912 also exhibit differences, however, the type series of these taxa were not studied in this research and must be evaluated in future studies.
