Aegilips zaitzevi Kovalev, 1974: 284 (♂).

Aegilips vena Fergusson, 1985 . Syn. nov.

Diagnosis

It shares the presence of incomplete notauli with A. atricornis , A. flavidicornis , and A. paucus . However, it can be easily distinguished due to the absence of mesoscutal and scutellar sculpture (other species of Aegilips present some degree of sculpture in the scutellum) and the presence an elongated 2rm vein, a character that sets it apart from other Palaearctic species of Aegilips (vein 2rm absent in other Palaearctic species of Aegilips ).

Redescription

MEASUREMENTS. Body 2.4–2.6 mm; antennae: 2.3–2.8 mm (♀), 2.3–2.6 mm (♂); wings: 2.8–3.1 mm.

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

HEAD. Head from triangular to sub-square-shaped in anterior view ( Fig. 1d ); 1.3 times as broad as high, malar area not expanded. Face smooth, punctate, with short uniform pubescence. Malar area coriaceous, 0.7–0.8 times as long as compound eye. Clypeus smooth, glabrous to sparcely pubescent, shortly projected; anterior tentorial pits small, indistinct. Transfacial distance 1.3 times as long as compound eye. Diameter of torulus equal to inter-toruli distance, slightly larger than torulus-eye distance. Frons, gena and occiput smooth and glabrous with few sparse setae; occipital and postocular carinae absents. In dorsal view 2.3 times as broad as long, broader than mesosoma. Compound eyes glabrous. In males POL: OOL: LOL is 6.0:5.0:3.0, diameter of lateral ocellus is 2.5; in females POL: OOL: LOL is 7.0:6.0:2.5, diameter of lateral ocellus is 2.0.

ANTENNAE. In males, antenna 14-segmented; flagellomeres cylindrical and pubescent, same width in all flagellomeres, placodeal sensilla present in all flagellomeres but scarce from F1 to F3; F1 not modified; antennal formula: 9.0(4.0), 3.5(3.0), 9.0(3.0), 9.0(3.0), 8.0(3.0), 8.0(3.0), 8.0(3.0), 7.0(3.0), 6.5(3.0), 6.5(3.0), 6.5(2.5), 6.0(2.5), 6.0(2.5), 8.0(2.5). In females, antenna 13-segmented; flagellomeres cylindrical and pubescent, same width in all flagellomeres, placodeal sensilla starting at F3 but scarce; antennal formula: 8.0(3.5), 3.5(3.0), 10.0(2.5), 10.0(2.5), 9.0(3.0), 9.0(3.0), 8.0(3.0), 8.0(3.0), 6.5(3.0), 6.0(3.0), 6.0(3.0), 9.0(3.0).

MESOSOMA. Pronotal plate smooth. Pronotum covered by long hyaline pubescence; ventrally carinate, dorsally smooth and punctuated. Mesoscutum 1.1–1.2 times as broad as long in dorsal view. Mesoscutum shiny, smooth, almost glabrous except for scarce short hyaline pubescence. Notaulus weak, effaced in anterior mesoscutum ( Fig. 2h ). Lateral mesoscutum smooth, glabrous; parapsidal signum and parascutal sulcus absents. Scutellum smooth, shiny ( Fig. 2h ), 0.7 times as long as mesoscutum; scutellar foveae rounded, large, slightly coarse, posteriorly defined by carina; presence of tenuous elongated 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. Mesopleural triangle strongly coarse, pubescent. Metanotal troughs densely pubescent, smooth except for some coarse sculpture in its lower margin. Propodeum alutaceous, covered with dense pubescence in laterals; central area glabrous defined by two longitudinal carinae, further divided in smaller cells by weak carinae.

FORE WINGS. Pubescent, marginal pubescence denser at apical third. Radial cell closed, 2.3–2.4 times as long as wide. Vein 2rm present, projected downwards ( Fig. 1g ).

METASOMA. Shorter than head + mesosoma. Petiole as long as wide, shorter than metacoxa, coarsely sculptured, shiny. Third metasomal tergum 2.3 times as long as fourth in dorsal view. Metasomal terga smooth and glabrous; T4 to T7 punctate.

Biology

Unknown.

Distribution
