Members of this tribe are characterised by the simple untoothed tarsal claw, the transverse subapical pit row on T3, and the transverse preoccipital welt or carina (Kimsey and Bohart 1991). With more than 1.500 species and 30 genera, Chrysidini is the largest tribe of Chrysididae. A total of 11 genera are known from Europe (Rosa and Soon 2012), five of which are found in the Nordic and Baltic countries (Paukkunen et al. 2014).
