Anergates atratulus Schenck, 1852

BELGIUM: • 1 alate gyne; N51.230° E4.415°; vi/2021; J. Jacobs leg.; coll. RBINS; pan trap (blue); W. Dekoninck det.

Remarks:

Anergates atratulus is an obligate parasitic and workerless species in nests of Tetramorium impurum / caespitum in Belgium ( VANKERKHOVEN & DEKONINCK, 2022). On the roof where we collected the A. atratulus gyne no Tetramorium -workers were found and hence we have no indication for any Tetramorium nests and settlement of this parasitic species on that rooF. It seems a gyne of this species arrived on the roof during her search for a nest to parasite, but this search was unsuccessful.
