Diagnosis
Species with higher variability than other Palaearctic Aegilips. It is morphologically similar to A. atricornis, from which it can be distinguished by the presence of complete notauli, excavated median mesoscutal furrow, carinate mesoscutum and rugose dorsal pronotum (notauli incomplete, median mesoscutal furrow absent and smooth mesoscutum and dorsal pronotum in A. atricornis). It can be distinguished from A. kozlovi and A. romseyensis – which also present complete notauli – by possessing weak horizontal carinae in the notauli and not having dorsal carinae in the pronotum (notauli with strong horizontal carinae and pronotum areolate in its entire surface in A. kozlovi and A. romseyensis).

Type locality
Sweden, Stockholm.
Redescription
MEASUREMENTS. Body: 2.5–2.8 mm; antennae: 2.5–3.0 mm (♂), 2.3 mm (♀); wings: 2.3–2.8 mm.
COLORATION. Head, mesosoma and metasoma black. Mandibles yellowish brown with darker teeth.
ANTENNAE YELLOWISH. Leg yellowish with brown coxae, black metacoxa. Veins of wings yellow.
HEAD. Head square-shaped in anterior view, 1.4 times as broad as high, malar area expanded. Face smooth and punctate, with short uniform pubescence. Malar area coriaceous, 0.7 times as long as compound eye. Clypeus smooth, glabrous, shortly projected; anterior tentorial pits small, indistinct. Transfacial distance 1.1 times as long as compound eye. Diameter of torulus larger than inter-toruli distance, same than torulus-eye distance. Frons, gena and occiput smooth and glabrous with few sparse setae; occipital and postocular carinae absents. In dorsal view 2 times as broad as long, broader than mesosoma. Compound eyes glabrous. POL: OOL: LOL is 7:4.5:3, diameter of lateral ocellus is 3.0.
ANTENNAE. In males, antenna 14-segmented; flagellomeres cylindrical and pubescent, same width in all flagellomeres, placodeal sensilla abundant in all flagellomeres; F1 not modified; antennal formula: 9(3.5), 3(3), 9(3.5), 8(3.5), 8(3.5), 8(3.5), 8(3.5), 8(3.5), 8(3.5), 7(3), 6.5(3), 6(3), 6(3), 9(3). In females, antenna 13-segmented; flagellomeres cylindrical and pubescent, same width in all flagellomeres, placodeal sensilla starting at F3 but not abundant until F5; antennal formula: 9(3.5), 3.5(3), 11(2.5), 9.5(3), 8.5(3), 8(3), 7.5(3), 7(3), 7(3.5), 7(3), 6.5(3), 6(3), 8(3).
MESOSOMA. Pronotal plate smooth. Ventral and anterior pronotum carinate; pronotal surface rugose, smoother near tegula (Fig. 2d). Mesoscutum 1.1 times as broad as long in dorsal view. Mesoscutum lightly rugose, punctate, almost glabrous except for short hyaline pubescence scattered across surface; transverse carinae variably extended: they range from covering entire mesoscutal surface to being only present in posterior mesoscutum. Notaulus weak but complete, with tenuous horizontal carinae (Fig. 2g); median mesoscutal furrow present but not strong. Lateral mesoscutum smooth and punctate; parapsidal signum absent; parascutal sulcus reduced to coarse band. Scutellum alutaceous, shiny; central scutellum smooth while strongly areolate at margins; 0.8 times as long as mesoscutum; scutellar foveae rounded, large, alutaceous, posteriorly defined by carina; presence of large and elongated pit next to inner margin of scutellar foveae. Interfoveal line complete, effacing in some individuals. Circumscutellar carina complete but not projected to form tooth in lateral view. Anterior and ventral mesopleuron carinate with rugose microsculpture, central and posterior mesopleuron smooth. Mesopleural triangle alutaceous, almost glabrous except for some short hyaline pubescence. Metanotal troughs glabrous, almost smooth except for some weak coarse sculpture. Propodeum smooth, divided in large cells; almost glabrous except for two densely pubescent areas below metanotal troughs; central propodeum divided in two symmetrical cells by median longitudinal carina; lateral propodeum heavily areolate.
FORE WINGS. Pubescent, marginal pubescence denser at apical third. Radial cell closed, 2.3 times as long as wide. Vein 2rm absent (Fig. 1e).

Biology
Known to attack Wesmaelius betulinus and W. subnebulosus (Fergusson 1986).
Distribution
Palaearctic. Sweden (Dalman 1823), United Kingdom (Cameron 1883), Austria, France (Giraud 1860), Germany (Hedicke 1914), Ukraine and Russia (Belizin 1951), Armenia and Georgia (Belizin 1961), China (Mata-Casanova et al. 2015b); first record for Portugal (Azores), Spain, Andorra, Ireland, Italy, Netherlands, Czech Republic, Slovenia, Bosnia and Herzegovina, Hungary, Norway and Romania.
Comments
The study of A. nitidulus was based on specimens deposited in the NHMUK identified as belonging to that species by Fergusson due to the loss of the type material. These specimens present the morphological traits mentioned in the original description of the species.
