Aegilips paucus Belizin, 1961: 153 (♂).

Diagnosis

Species with incomplete notauli like A. atricornis , A. flavidiornis and A. zaitzevi . Unlike A. flavidicornis and A. zaitzevi it presents an areolate scutellum (scutellum smooth in A. flavidicornis and A. zaitzevi ). It is morphologically close to A. atricornis ; however, A. paucus has almost effaced notauli and posterior carina of scutellar foveae weakening in its central area (in A. atricornis the notauli though incomplete are strongly apparent and basal carina of scutellar foveae is strong throughout).

Redescription

MEASUREMENTS. Body: 2.4 mm; antennae lost; wings: 2.5 mm.

COLORATION. Head and mesosoma black. Mandibles yellowish brown with darker teeth. Leg yellowish brown with darker coxae. Veins of wings yellowish.

HEAD. Triangular-shaped in anterior view, 1.1 times as broad as high, malar area not expanded. Face smooth and punctate, with short uniform pubescence. Malar area coriaceous, 0.6 times as long as compound eye. Clypeus smooth, glabrous, shortly projected; anterior tentorial pits small, indistinct. Transfacial distance as long as compound eye. Diameter of torulus larger than inter-toruli and torulus-eye distances. Frons, gena and occiput smooth and glabrous with few sparse setae; occipital and postocular carinae absents. In dorsal view 1.3 times as broad as long, broader than mesosoma. Compound eyes glabrous. POL: OOL: LOL is 6.0:5.0:2.0, diameter of lateral ocellus is 2.0.

ANTENNAE. Lost.

MESOSOMA. Pronotal plate smooth. Pronotum smooth and punctate; ventral pronotum carinate, presence of some short and weak ridges at the edges of the pronotal plate, not extended into the rest of the pronotal surface. Mesoscutum 1.3 times as broad as long in dorsal view. Mesoscutum smooth, shiny and glabrous except for some scarce hyaline hairs. Notaulus incomplete and very tenuous, hard to notice, reduced to posterior mesoscutum ( Fig. 3f ); median mesoscutal furrow short and weakly excavated, almost unnoticeable. Lateral mesoscutum smooth, punctate; parapsidal signum and parascutal sulcus absents ( Fig. 3g ). Scutellum heavily areolate, 0.6 times as long as mesoscutum; scutellar foveae rounded, large, alutaceous, posteriorly defined by carina weakening in central scutellum; presence of small pit next to inner margin of scutellar foveae. Interfoveal line complete. Circumscutellar carina complete but not projected to form tooth in lateral view. Anterior and ventral mesopleuron carinate, central and posterior mesopleuron smooth; ventral carinae reaching metapleura. Mesopleural triangle with weak coarse sculpture, covered by dense short pubescence. Metanotal troughs glabrous, almost smooth except for some weak coarse sculpture. Propodeum coriaceous, densely pubescent, divided in large cells; central area longitudinally divided by median carina, with some transverse weak carination.

WINGS. Pubescent, marginal pubescence denser at apical third. Radial cell closed, 2.6 times as long as wide. Vein 2rm absent.

METASOMA. Lost.

Biology

Unknown.

Distribution

Palaearctic. Kazakhstan ( Belizin 1961); Mongolia ( Kovalev 1974).
