Diagnosis

This species can easily be separated from its single congener with an overlapping range in the Nearctic ( B. pretiosus Cushman, 1936 ) by the following characteristics: face variably darkened; propodeum with area petiolaris and area superomedia confluent (i. e. transverse carina in the middle of the propodeum is absent); mesoscutal setae about the same length as metapleural and propodeal setae (modified from Wahl and Gauld (2002)).

Distribution

Finland (new record); widespread in the Holarctic.

Morphological remarks

The dorsal tooth of this species has, like some of its congeners ( Wahl and Gauld 2002), an impressed apex (Fig. 3 View Figure 3 ), making the mandible appear tridentate (similar to Diplazontinae). In common with other species of Brachycyrtus , many carinae are unusually well developed amongst Darwin wasps, see, for example, the nearly complete propodeal carinae and the epomia (Fig. 3 View Figure 3 ).
