Aegilips longicellus Belizin, 1951: 372 (♀).

Diagnosis

Species with incomplete notauli like A. atricornis , A. flavidicornis , A. paucus and A. zaitzevi . It can be distinguished from all these species by not having posteriorly defined carinae in the scutellar foveae and possessing incomplete interfoveal line (scutellar foveae always defined by a posterior carina and interfoveal line complete in A. atricornis , A. flavidicornis , A. paucus and A. zaitzevi ).

Type material

Holotype TADJIKISTAN • ♀; “ Avzob , 3000 m a.s.l., 31 Aug. 1946; V. Gussakovskij ” (white label); “Holotype Aegilips longicellus ♀ V. Belizin det” (red label); ZIN.

Material examined

UNITED KINGDOM • 1♂; Scotland , Argyleshire, Armidale; 12. Jul. 1912; J.R. Malloch leg.; USNM .

Redescription

MEASUREMENTS. Body 2.7 mm; antennae: 1.8 mm (♀, from scape to F8), 2.6 mm (♂); wings: 2.9 mm.

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

HEAD. Triangle-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 and 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 1.6 times as broad as long, broader than mesosoma. Compound eyes glabrous. POL: OOL: LOL is 6.0:5.5:2.5, diameter of lateral ocellus is 2.0.

ANTENNAE. In females, flagellomeres cylindrical and pubescent, same width in all flagellomeres, placodeal sensilla starting at F2; antennal formula (from scape to F8): 8.0(3.5), 4.0(3.0), 9.0(2.5), 9.0(2.5), 9.0(2.5), 8.0(2.5), 7.5(2.5), 7.0(2.5), 6.0(3.0), 6.0(3.0).

MESOSOMA. Pronotal plate smooth. Pronotum smooth, scarcely pubescent, with some irregular ventral carinae. Mesoscutum 1.3 times as broad as long in dorsal view. Mesoscutum smooth, shiny, scarce short anterior white setae, central mesoscutum glabrous. Notaulus weak, incomplete, without horizontal carinae; median mesoscutal furrow absent. Lateral mesoscutum smooth and glabrous; parapsidal signum absent; parascutal sulcus reduced to few weakly impressed cells. Scutellum alutaceous; central scutellum smooth while strongly areolate at margins; 0.6 times of mesoscutal length; scutellar foveae rounded, large, alutaceous, not posteriorly defined by carina ( Fig. 3b ); presence of small pit next to inner margin of scutellar foveae. Interfoveal line incomplete ( Fig. 3b ). 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 weakly carinate, short hyaline pubescence uniformly distributed. Metanotal troughs glabrous, almost smooth except for some weak coarse sculpture. Propodeum strongly alutaceous, densely pubescent, divided in large cells; central area divided in two symmetrical areas by median longitudinal carina; these two large areas are also asymmetrically divided by some weaker and irregular transverse carinae.

FORE WINGS. Pubescent, marginal pubescence denser at apical third. Radial cell closed, 2.3 times as long as wide. Vein 2rm absent.

METASOMA. Shorter than head + mesosoma. Petiole as long as wide, shorter than metacoxa, coarsely sculptured, shiny. Third metasomal tergum 2.0 times as long as fourth in dorsal view. Metasomal terga not punctate.

Biology

Unknown.

Distribution

Palaearctic. Tajikistan ( Belizin 1951), Chelyabinsk oblast ( Belizin 1961), first record for United Kingdom.
