Explanation of Names
Euschistus variolarius (Palisot de Beauvois 1805)
11-15 mm(1)
The only reliable way to separate variolarius from servus is a ventral view. The males of the one-spot stinkbug (E. variolarius) have one big spot on the pygophore; servus, none.

The females are differentiated by a small dark spot on the anterior corner on the edge of each abdominal segment in servus (no spot in variolarius); sometimes you can see it on the dorsal view. (D.B. Thomas, pers. comm. to =v=, 11/05/09)
