Campyloneura Fieber, 1861: 388 (new name for Camptoneura Fieber, 1858 ). Type species: Capsus virgula Herrich-Schaeffer, 1835 (by monotypy). Diagnosis. Recognized by the following characters: body smooth, elongate, gracile, 3.0–4.4 ( Figs. 1–6 ); antennal segment II long, 1.5–2.0 X as long as basal width of pronotum; labium long and thin, reaching hind coxa ( Fig. 13 ); pronotal collar flat, well demarcated, distinctly wider than antennal segment I; calli weakly raised; posterior margin of pronotum strongly concave ( Fig. 8 ); scent-gland evaporatory area large, triangular, with dorsally oriented, tongue-shaped peritreme ( Fig. 15 ); membrane with two round cells distinctly not reaching apex of cuneus; pulvillus large, attached to inner claw surface, with characteristic pulvillar combs ( Figs. 11, 12, 16, 17 ); both parameres Lshaped, left paramere distinctly larger than right one ( Figs. 19–26 ). Description. Female. COLORATION. Dorsum generally whitish yellow. Head dark brown or yellow with reddish vertex; antennal segment II entirely or mostly dark brown; pronotum with wide, transverse, reddish to dark brown band across calli; hemelytron semitransparent, more or less darkened along midline or with transverse reddish spot along apex of corium; legs uniformly yellow, apical part of hind femur and basal part of hind tibia slightly darkened or with reddish tinge ( Figs. 1–6 ). SURFACE AND VESTITURE. Dorsum shiny, smooth, hemelytron weakly rugose. Body with whitish simple setae, notably long, erect to semierect on head, pronotum and femora, shorter, semiadpressed elsewhere; tibial spines whitish to yellow, distinctly longer than diameter of tibia. STRUCTURE. Body elongate, macropterous. Head : Spherical, transverse, about 1.3 X as wide as high in frontal view, moderately protruded ventrally below eyes; frons convex, weakly protruded anterior to eyes and broadly rounded in dorsal view ( Figs 7, 8, 13 ); clypeus ventrally oriented, basally delimited by slightly depressed epistomal suture; mandibular plate triangular; maxillary plate rectangular, slightly longer than high, distinctly elevated apically; eye large, hemispherical, about two-thirds height of head in lateral view; antennal fossa located well above ventral margin of eye; antennal segment I relatively short, slightly swollen; segment II long and thin; segments III and IV filiform; labium long and thin, reaching or slightly surpassing hind coxa. Thorax : Pronotum with slightly sinuate anterior margin, weakly concave lateral margins and strongly excavate posterior margin; pronotal collar flat, distinctly wider than antennal segment I, posteriorly delimited by shallow but distinct sulcus; calli only slightly raised, medially not delimited, posteriorly demarcated by shallow impressed line; mesonotum broadly exposed; metathoracic spiracular opening elongate-oval, with distinct characteristic sculpture dorsally ( Figs. 9, 14 ); metathoracic scent-gland evaporatory area large, triangular, with tongue-shaped, dorsally oriented peritreme ( Fig. 15 ). Hemelytron: Semitransparent, long, with cuneus surpassing apex of abdomen; corium with almost straight costal margin, R+M vein well developed, almost reaching apex of corium, subparallel to costal vein; medial fracture not expressed; cuneus about twice as long as wide at base; membrane with two cells not reaching apex of cuneus. Legs : Long and thin, femora slightly flattened, hind femur almost reaching apex of abdomen; tibiae distinctly longer than respective femur; tarsus three-segmented, distinctly swollen apically, with all segments almost equal in length; unguitractor with two widely separated columns of lamellae ( Fig. 18 ); claw abruptly bent in apical third ( Figs 11, 12 , 16,17), with dense claw setae on outer surface; inner surface of claw with large semicircular pulvillus equipped with pulvillar combs; parempodia asymmetrical, with outer parempodium slightly shorter than inner. GENITALIA. Dorsal labiate plate membranous, with large, weakly sclerotized, bean-shaped sclerotized rings ( Figs. 31 , 35, 36 ); lateral oviducts long; posterior wall with short, strongly sclerotized, claw-shaped sclerites at sides ( Fig. 32 ); vulva membranous, without associated sclerites; vestibulum entirely membranous; first gonapophysis gradually tapering, finely serrate dorsally and ventrally ( Fig. 33 ); second gonapophysis somewhat dilated subapically, with comparatively large and widely separated prongs dorsally ( Fig. 34 ). Male . COLORATION, STRUCTURE, SURFACE AND VESTITURE. As in female GENITALIA: Genital capsule about 30% of abdomen, well sclerotized, somewhat longer than wide, conical, broadly rounded apically, without additional processes ( Konstantinov et al. 2018 : fig. 10A); supragenital bridge absent; left paramere 1.5–2.0 X as long as right one, falciform, with gradually curved, flattened apical process and swollen body ( Figs. 19–26 ); phallotheca membranous, with more or less sclerotized dorsal wall; endosoma subdivided into vesica and conjunctiva; vesica membranous, apically dentate or with large sclerotized appendage ( Figs. 27–30 ). Key to species 1 Corium with large transverse red spot along apical margin. Cuneus semitransparent, whitish, with narrowly reddish base and costal margin ( Figs. 1, 2 ). Smaller, total length less than 3.1............................................ C. joceliae - Corium with dark brown longitudinal stripe along inner margin, rarely uniformly whitish. Cuneus bright yellow, with dark red apical third ( Figs. 3–6 ). Larger, total length more than 3.6.............................................. C. virgula
