Gasteruption minutum (Tournier, 1877)

BELGIUM: • 1 ♂; N51.251° E4.418°; vii/2020; J. Jacobs leg.; coll. FV; pan trap (yellow); F. Verheyde & A. De Ketelaere det.

Remarks:

Based on the specimens in the collection of RBINS, this species is rather uncommon in Belgium. It appears to have a more southern distribution (VAN ACHTERBERG, 2013) and is thus possibly thermophilic. Typical for this species are the lateral protuberances just below the eyes (frontal view).
