Notes.

Barcoding cluster BOLD:ACZ1254 includes sequences of specimens from Finland, Germany, Norway, United Kingdom, and Canada. Specimens in this cluster from both sides of the Atlantic were reared from Rheumaptera hastata (the host of the holotype): from the United Kingdom (CNCHYM49288=MRS_JFT 0154) and from Canada (CNC1447813). Morphological examination resulted in some differences in leg colouration between Canadian and European specimens available to us (see Figs 46 , 47 ). However, T1-T3 shape and structure are similar and the host information and DNA barcoding also point towards all of our specimens representing one species. Based on this integrative species concept from studying specimens from German as well as some Canadian and European material, and considering the hosts of this species, we here consider BIN BOLD:ACZ1254 to represent C. eulipis and report this species for the Nearctic for the first time. Other specimens in this BIN were reared from Operophtera brumata (MRS 0048=MRS_JFT0048, MRS 0049=MRS_JFT0049, MRS 0050=MRS_JFT0050) in Finland and Norway and from Operophtera bruceata (CNCHYM 00330, CNCHYM 00331) in Canada. There is another specimen from Austria (CNC990841=MRS_JFT0743) that morphologically matches C. eulipis , yet clusters in a different BIN (BOLD:AEV7769) which has a p-distance of 1.9% to all other specimens that we identified as C. eulipis and is reared from Hydria cervinalis (Scopoli, 1763), a host so far not reported for this species. Resolving this goes beyond the scope of this paper, for the purpose of this manuscript we prefer to retain this specimen as " Cotesia cf. eulipis ". This species is illustrated in Figs 46 , 47 .
