Notes

The holotype was found hibernating near Vienna, below the bark of a common pine. A variable species; the metasoma can vary from nearly entirely black to the second tergite coloured red-brown. Superficially resembles Ichneumon inquinatus , but the scutellum is completely black. Specimens with a black scutellum and T 2 (- 3) darkened or black resemble darker variants of I. boreellus (and possibly I. ignobilis ), which are very rare in lowlands, but microscopy is still necessary to check the sculpture of the first tergite and confirm the identification with certainty ( Hilpert 1992). One specimen in Norway was found by sieving the soil. Uncertain records exist from France, Lithuania and Russia (iNaturalist).

Status: Confirmed.

First record: Ca. 1888 ( Kriechbaumer (1888), Austria).
