Popovineura Fedotova et Perkovsky , gen. n.

T y p e s p e c i e s: Popovineura nacta Fedotova et Perkovsky , sp. n.

D e s c r i p t i o n. M a l e ( fig. 3, 1–8; 8, 1, 2 ). Body is very wide and swollen, slightly longer than antennae and slightly shorter than wings. Head laterally is almost round. Eyes with wide bridge, occiput wide rounded. Antennae are 2+11-segmented, scape is enlarged distally, pedicel round. All flagellomeres with distinct necks, that are shorter than basal enlargements. Basal enlargement mostly parallelsided, only middle flagellomeres with almost round basal node. Distal flagellomeres with short necks. Eleventh flagellomere ovoid. Proximal flagellomeres are slightly wider and longer than distal ones. Flagellomeres with basal whorl of relatively short setae positioned in single row and medial whorl of very long setae densely covering medial part of basal enlargement. Sensorial filae of flagellomeres are invisible. Mouthparts are short and wide. Palpi two-segmented, second segment longer than first. Wing is widely enlarged and rounded distally, vein R 4+5 slightly curved, located near C, enters wing margin before its apex, R s absent, Cu located far from wing margin, not forming fork. Hind femur almost as long as middle, hind tibia is much longer than the middle one. Hind femur is shorter than tibia. Tarsal claw simple, hook-form. Abdomen is evenly swollen and wide rounded distally, strongly narrowed before genitalia. Genitalia are transversal. Gonocoxite is narrow, without basal lobe or enlargment, slightly curved distally. Gonostylus is narrow, with apical dent, slightly shorter than gonocoxites. Cerci are wide, cordiform, almost reaching apex of gonocoxites, with wide round lobe dissected by triangular excision. Parameres or basal enlargement of gonocoxites absent. Hypoproct is whole, rounded apically. Aedeagus is very narrow, almost parallelsided, much longer than gonocoxites.

C o m p a r i s o n. By the shape of the body, arrangement of wing veins, the new genus is closely related to Brachineura Rondani, 1840 ( Mamaev, 1967; Gagné, Solinas, 1996), differing from it by the 2+11-segmented antennae, presence of much longer necks of flagellomeres not covered by dense scales, long legs and very narrow gonocoxites and gonostylus, very long aedeagus, short mouthparts, 2-segmented palpi, and smaller body size.

E t y m o l o g y. The genus is named in honour of paleoentomologist Yu. A. Popov, the leading Russian expert in fossil Hemiptera. The name is combined of his second name and the second part of the name Brachineura . Gender feminine.
