description: Campyloneura Fieber, 1883
Camptoneura Fieber, 1858: 309 (junior homonym of Camptoneura Macquart, 1843 (Diptera, Ulidiidae)).
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).
