Head yellow to brown, genal processes pale to bright yellow; clypeus pale brown to black. Eyes red to dark brown, ocelli orange. Antenna pale yellow, segments 3–8 with more or less distinct brown apices, segments 9–10 entirely dark brown. Thorax entirely pale to bright yellow; mesopraescutum with two bright yellow to orange patches along the fore margin; mesoscutum with four broad bright yellow to orange longitudinal stripes. Forewing with whitish to dark brown veins and membrane with brown to dark brown pattern consisting of two broad transverse stripes: submarginal one stretching from apical part of costal vein to median part of cell cu1 leaving light areas in cells r2, m1, m2 and cu1 along the margin, and median one stretching from median part of vein C+Sc to apical part of anal vein; membrane between two bands colourless, sometimes with few dark brown dots in cells and sometimes on veins. Legs pale to dirty yellow, sometimes with brownish femora, meracanthus of metacoxa pale yellow. Abdomen yellow to brown; terminalia pale yellow to orange. Female proctiger with dark apex. Females with slightly lighter head and abdomen. Structure. Head, in profile, weakly inclined from longitudinal body axis (<45°). Vertex trapezoidal, flat, anteriorly produced into transverse lobe on either side of mid-line, hind margin around lateral ocelli not raised, covered with microscopical setae; genal processes short, swollen, slightly conical apically, covered with short setae. Pronotum with two pronounced lateral and one relatively shallow sublateral tubercles on either side. Forewing rhomboidal; vein C+Sc strongly, unevenly curved, pterostigma long, vein Rs almost straight, strongly curved to fore margin apically; vein M about as long as either of veins M1+2 and M3+4; surface spinules large, very dense, present in all cells, leaving narrow spinule-free stripes along the veins, forming hexagons, less developed on unpigmented areas; radular spinules not pronounced. Metatibia with 5–7 apical spurs. Terminalia. Male. Proctiger tubular; sparsely covered with moderately long setae in apical half. Subgenital plate elongate; with sparsely spaced moderately long setae in apical half. Paramere narrowly lamellar; with recurved apico-anterior process on pedicel and long apico-posterior lobe with inwards directed sclerotised anterior tooth situated at base of the lobe; lobe about twice longer than process; outer face sparsely covered with moderately long setae mostly in apical half, inner face densely covered with long thick bristles apically. Distal segment of aedeagus massive, broadly evenly expanding towards apex; with one small apico-posterior tubercle; lateral lobes moderately long, dilated towards apex which is irregularly rounded and with frayed margin.—Female. Proctiger subglobular, pointed apically; dorsal margin, in profile, strongly bent downwards; densely covered with moderately long setae. Subgenital plate subglobular, rounded apically, with tiny apical process; densely covered with long setae in apical half. Host-plant. Capsicum annuum L. ( Solanaceae ). Distribution. Reported from Argentina ( Buenos Aires , Entre Ríos ), Brazil ( Minas Gerais , Paraná , Santa Catarina , São Paulo ) ( Burckhardt 1987 ; Burckhardt & Queiroz 2012; Burckhardt et al. 2012). Holotype ♂ from São Paulo , Piracicaba, viii–ix.1969 , Capsicum annuum (M. de Menezes) (BMNH, dry), not examined here; Burckhardt 1987 . Material examined. Argentina ( Buenos Aires , Entre Ríos ), Brazil ( Minas Gerais , Paraná ). Comments. Russelliana capsici resembles R. dimorpha and lycii in a weakly inclined head (<45°), in short swollen genal processes, in a forewing with a brown pattern, a strongly curved vein C+Sc and a vein Rs strongly curved to the fore margin apically, in a tubular male proctiger, in a cuneate male subgenital plate, in a narrowly lamellar paramere bearing a short apico-anterior process and a long apico-posterior lobe with a tooth, in a distal segment of the aedeagus broadly expanded towards apex and bearing lateral lobes with a frayed margin apically, in a subglobular female proctiger with its dorsal margin bent downwards, and a subgenital plate densely covered by setae. R. capsici differs from the two species in the absence of sexual dimorphism. It differs from R. dimorpha in shorter setae on the female subgenital plate, and from R. lycii in a recurved apico-anterior process of the paramere and a female subgenital plate bearing an apical process.
