Notes.

The non-reared German specimen was identified as Rasivalva desueta by comparing it with the detailed original description ( Papp 1989) and Oltra-Moscardó and Jiménez-Peydró (2005). One male specimen (MRS-JFT 0582) in this cluster, also from Germany, was possibly reared from Eilema depressa (Esper, 1787) which would represent the first host record for this wasp species. However, the wasp cocoon could not be associated unequivocally with host remains and hence the host association needs to be confirmed. We also report Sweden as a new country record based on a male specimen we examined (CNC602554), which is morphologically similar to the German female (except for darker metafemur and less broad T1 and T2, in agreement with the original description of a male paratype) as well as matching DNA barcode sequences. This species is illustrated in Figs 44 , 45 .
