Members of Virgichneumon can be distinguished from related ichneumonine by the presence of a carinate propodeum with a defined area superomedia and the structure of the areolet (a small pentagonal or quadrangular in the ). The 'zebratus' suggests banded coloration on the mesosoma or metasoma, though precise diagnostic features for V. zebratus require examination of material. Separation from congeneric depends on details of shape, proportions, and punctation on the mesoscutum.
Distribution
The was described from North America (United States), with Cresson's original description based on specimens from the eastern or midwestern United States. Records in the iNaturalist database indicate observations from North America, though specific locality details require verification against primary literature.
