Remarks. The species is common and widespread in the Nordic and Baltic countries. The northernmost records are from Finnish Lapland (Li: Utsjoki) and Murmansk Oblast (Lps: Pasvik Nature Reserve, Humala & Polevoi 2011). As many other species of the C. ignita group, C. schencki was not separated from C. ignita until the late 1950s, when it was described by Linsenmaier as a subspecies of C. ignita .

In the study of Estonian Chrysididae by Soon (2004) C. schencki was confused with C. corusca . Further studies, including a study of type specimens of both species, have revealed that both species occur in Estonia. Studies of mitochondrial DNA have shown that C. schencki significantly differs genetically from other closely related species of the Chrysis ignita complex ( Soon et al. 2014). However, morphologically the males in particular can be very difficult to determine. Females are usually relatively well distinguished by their thin mandibles (Smissen 2010). According to recent DNA barcode analyses, C. schencki can be divided into two distinct genetic lineages in northern Europe ( Soon et al. 2014). Preliminary studies suggest that there could be also slight morphological differences between the lineages.
