Diagnosis

Species with incomplete notauli like A. immunis , from which can be distinguished by having a median mesoscutal furrow, a carinate sculpture in anterior mesoscutum and a strongly areolate scutellum (median mesoscutal furrow absent, mesoscutum completely smooth and scutellum smooth to tenuously areolate in A. immunis ). This species is also morphologically similar to A. eucharoides , however it can be easily distinguished by the strongly areolate scutellum (scutellum alutaceous to rugose, never areolate, in A. eucharoides ).

Etymology

The specific name makes reference to the distribution area of the type series.

Description

LENGTH. Body: 3.5 mm. Antennae: 3 mm (♀). Wings: 3.3 mm.

COLORATION. Head, mesosoma and metasoma black. Mandibles yellowish brown with darker teeth. Antennae brown with black first segment. Legs yellowish brown, upper femur and coxae darker. Veins of wings brownish.

HEAD. Triangular-shaped in anterior view. Face smooth, covered with abundant white setae. Width of head 1.2 times its height in anterior view and 1.9 times its length in dorsal view. Malar sulcus coriaceous, 0.6 times height of compound eye. Transfacial line as long as compound eye height. Diameter of toruli equal to torulus to compound eye distance but larger inter-toruli distance. Clypeus shortly defined, convex, margins densely covered by facial pubescence. Occipital and postocular carinae absent. Compound eyes glabrous. In females, POL:OOL:LOL ratio = 7:4.5:3, ocelli diameter being 2.5. Frons and occiput smooth covered by some scarce hyaline hairs, gena densely pubescent.

ANTENNAE. Cylindrical flagellomeres covered with pubescence. Female antennal formula: 9(5), 3.5(3), 9(2), 8.5(2), 8.5(2), 8(2.5), 8.5(2.5), 8(3), 7(3), 6.5(3), 6(3), 6(3), 11(3). Placodeal sensilla start at at F4 but not abundant until F 5 in females.

MESOSOMA. Pronotum smooth, punctate, with shortly extended ridges from pronotal plate margin that become transverse carinae in ventral pronotum ( Fig. 4E ). Mesoscutal width 1.1 times its length in dorsal view. Mesoscutum smooth, shiny, almost glabrous except for a few short setae; weak carinate sculpture in region between notauli more distinct in anterior mesoscutum ( Fig. 4D ). Lateral region of mesoscutum smooth and glabrous, except for some peripheral short setae and punctures. Notauli weakly impressed, effaced in anterior mesoscutum, presence of weak internal carinate sculpture( Fig.4D ); median mesoscutal furrow short but distinct. Parapsidal signum tenuous, parascutal sulcus absent. Scutellar length 0.6 times that of mesoscutum in dorsal view. Scutellum alutaceous, shiny, completely covered by small areolate sculpture ( Fig. 4D ). Scutellar foveae triangular, smooth, without any internal carinae, basally defined by a carina; lateral pits of scutellar foveae elongated and deeply excavated. Interfoveal line present. Circumscutellar carina complete, clearly defined, not dorsally projected at scutellum apex. Mesopleuron glabrous, shiny, with internally carinate transverse groove alutaceous, presence of coarse sculpture in anterior mesopleuron. Mesopleural triangle densely covered by long hyaline hairs. Metanotal troughs coarse, densely pubescent. Propodeum coriaceous, pubescent; central area longitudinally divided in two symmetrical areas by a median carina; both areas are further divided by short transverse carinae.

WINGS. Pubescent. Radial cell of forewing closed, 3 times longer than wide. Marginal pubescence of the forewing denser at apical third.

METASOMA. Longer than head + mesosoma. Petiole about as long as metacoxa ( Fig. 4F ), smooth and shiny. Third metanotal tergum 2.9 times as long as fourth tergum in dorsal view. Fifth, sixth and seventh metanotal terga visible in dorsal view. Metanotal terga smooth and glabrous, never punctate.

Biology

Unknown.

Distribution

Palaearctic. Only collected from Norway.
