Lectotype female in NHM, examined. Synonymized with E. bicolor by Boucek & Askew, (1968: 15). Material ( 26♀ 18♂ ). Belgium : 3♀ 3♂ (ZSM), this material includes 3♀ 3♂ from Pieris rapae ; France : 1♀ 2♂ (NHM), this material includes 2♂ from a caterpillar on Artemisia vulgaris ; Hungary : 2♀ 9♂ (MZLU, NHM); Romania : 1♀ (NHM); Sweden : 7♀ 1♂ (MZLU, NHM); United Kingdom : 12♀ 5♂ (NHM), this material includes 1♀ from Noctua comes on Corylus avellana . Diagnosis. Frons below level of toruli with pale area not extending laterally to the eye but with a wide dark stripe between pale area and eye in both sexes (Figs 27 , 28 ); midlobe of mesoscutum usually without median groove or carina (Fig. 49 , 56 ) (sometimes with a weak median groove at very base); posterior part of midlobe mesoscutum wide (Fig. 56 ), ratio width base of midlobe (a)/width base of sidelobe (b) = 0.80 +/- 0.048 (female), 0.80 +/- 0.054 (male), width base of midlobe/width base of entire mesoscutum = 0.29 +/- 0.018 (female), 0.28 +/- 0.014 (male), n=9 for female and male respectively. Very similar to E. bicolor , distinguished from this species by the wide posterior part of midlobe of mesoscutum. Hosts. Noctuidae : Noctua comes Huebner on Corylus avellana . Pieridae : Pieris rapae (L.). From an unidentified caterpillar on Artemisia vulgaris . Distribution. France (Corsica) ( Walker 1872a ), Belgium, Hungary, Romania, Sweden, United Kingdom (new/confirmed records). Remarks. Euplectrus intactus was synonymized with E. bicolor by Boucek and Askew (1968) , but DNA-data and a renewed analysis of the morphology both support that these are different species. Genetic data. Barcoded specimens of Euplectrus intactus exhibited an intraspecific variation of 6.9% and a pronounced geographic subclustering (NJ-tree, Suppl. material S2). One of the nine different haplotypes in E. intactus was recorded from four countries (specimens with BIN BOLD:ACR7308 from Hungary and Romania, Sweden and the UK, Fig. 63 ). The other eight haplotypes were recorded from a single country each. More than one haplotype occurs in Sweden (four haplotypes), Belgium (two haplotypes), and Hungary (three haplotypes). As in the other Euplectrus species with high haplotype divergence, a broader sampling from different populations and geographic regions is required to clarify the status of different haplotypes of the species.
