Aegilips ustulatus Belizin, 1973: 31 (♂).

Diagnosis

Species with complete and not internally carinate notauli and smooth mesoscutum, similar to A.nitidulus . However, most of the mesopleural surface is completely wrinkled, a character exclusive of this species (other Palaeartic species of Aegilips present some antero-ventral carinae in the mesopleuron but they never reach central mesopleuron).

Type material

Holotype KRYGYZSTAN • ♂; “ Aegilips ustulatus Belizin ” (red label); “ Kirgiziya , Akbosaga , 5 Aug. 1964; (V. Tobias) ” (white label); ZIN.

Type locality

Kyrgyzstan, Osh oblast, Ak-Bosogo.

Redescription

MEASUREMENTS. Body: 2.3 mm; antennae: 3.0 mm (♂); wings: 3.0 mm.

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

HEAD. Head square-shaped in anterior view, 1.4 times as broad as high, malar area expanded. Face smooth, punctate, with short pubescence except in central rostrum, which is glabrous. Malar area coriaceous, 0.7 times as long as compound eye. Clypeus smooth, glabrous and shortly projected; anterior tentorial pits small, indistinct. Transfacial distance 1.3 times as long as compound eye. Diameter of torulus larger than inter-toruli distance and torulus-eye distance. Frons, gena and occiput smooth, glabrous except for few sparse setae; occipital and postocular carinae absent. In dorsal view 1.7 times as broad as long, broader than mesosoma. Compound eyes glabrous. POL: OOL: LOL is 6.5:5.0:3.0, diameter of lateral ocellus is 2.0.

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: 9.0(3.5), 3.0(3.0), 10.0(3.0), 10.0(3.0), 10.0(3.0), 9.0(3.0), 9.0(3.0), 9.0(3.0), 9.0(3.0), 9.0(3.0), 9.0(3.0), 9.0(3.0), 8.0(3.0), 10.0(3.0).

MESOSOMA. Pronotal plate smooth. Pronotum covered by short pubescence, ventral pronotum densely wrinkled ( Fig. 3a ). Mesoscutum almost as broad as long in dorsal view (25:24). Mesoscutum shiny, smooth; short hyaline pubescence uniformly distributed across its surface. Notaulus complete, not internally carinate, coarse margins; median mesoscutal furrow present. Lateral mesoscutum smooth and punctate; parapsidal signum absent; parascutal sulcus absent, presence of coarse band instead. Scutellum smooth with rugose margins, 0.6 times as long as mesoscutum; scutellar foveae rounded, smooth, posteriorly defined by carina weakening in central scutellum; presence of large and elongated pit next to inner margin of scutellar foveae. Interfoveal line complete. Circumscutellar carina complete but not projected to form tooth in lateral view. Mesopleural surface densely wrinkled except for dorso-posterior margin ( Fig. 3a ). Mesopleural triangle strongly coarse. 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.

FORE WINGS. Pubescent, marginal pubescence denser at apical third. Radial cell closed, 3.0 times as longas wide. Vein 2rm absent.

METASOMA. Shorter than head + mesosoma. Petiole as long as wide, shorter than metacoxa, coarsely sculptured, shiny. Third metasomal tergum 3.2 times as long as fourth in dorsal view. Metasomal terga smooth and glabrous; T4 to T7 punctate.

Biology

Unknown.

Distribution

Palaearctic. Kyrgystan ( Belizin 1973).
