Euplectrus
intactus

(NHM), this material includes

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.
