Description.
Coloration. Head including genal processes pale yellow to dark brown, genal processes with dark tips, vertex with pale to dark brown pattern; clypeus brown to black. Eyes pale yellow to brown, ocelli orrange to red. Antenna dirty yellow to brownish, segments 1–2, 9–10 entirely dark brown, segments 3–8 with dark brown apices. Pronotum of the same colour as vertex, with the same orange to dark brown pattern, sometimes distinctly paler than mesonotum; mesopraescutum pale yellow to orange, with two brown patches along the fore margin and two orange patches posteriorly, sometimes entirely orange; mesoscutum orange with four broad and, in the middle, one narrow brown longitudinal stripes; mesoscutellum pale yellow along the margin, brown in the middle. Metanotum orange to dark brown. Forewing with pale yellow to brown veins and whitish membrane with conspicuous dark brown pattern consisting of constant patch along vein Cu1b and dots scattered over entire surface, partly confluent in apical part, forming broad submarginal stripe stretching from apical part of costal vein to apex of vein Cu1a, leaving light areas in cells r2, m1 and m2 along the margin; sometimes with relatively distinct median broad stripe stretching from apical part of cell r1 to base of vein Cu1b. Legs yellow to brown, often with dark brown femora and distal tarsal segments, meracanthus of metacoxa pale to bright yellow. Abdomen yellow to dark brown. Females often slightly lighter with ventrally lighter abdomen. Male terminalia dark brown, sometimes paramere yellow. Female proctiger dark brown, subgenital plate brown.
Structure. Head, in profile, strongly inclined from longitudinal body axis (> 45°). Vertex subtrapezoidal with indented foveae, anteriorly produced into transverse tubercle on either side of mid-line, with raised hind margin around lateral ocelli, covered with short setae; genal processes conical, slender, subacute apically, distinctly shorter than vertex; covered with moderately long setae. Pronotum with two pronounced lateral and one relatively shallow sublateral tubercles on either side. Forewing oval, broadly, unevenly rounded apically; vein C+Sc weakly curved, pterostigma long, vein Rs weakly sinuous, slightly curved to fore margin apically; vein M slightly longer than either of veins M1+2 and M3+4; surface spinules very dense, present in all cells, leaving no spinule-free stripes along the veins, irregularly spaced; radular spinules not pronounced. Metatibia with 6–7 spurs.
Terminalia. Male. Proctiger tubular; sparsely covered with moderately long setae. Subgenital plate short, subglobular; with sparsely spaced moderately long setae. Paramere broadly lamellar; with apico-anterior process on pedicel, median hump with apically sclerotised median tooth, and slightly bulged apico-posterior lobe; process, hump and lobe of subequal length; outer face sparsely covered with moderately long setae mostly in posterior part, inner face densely covered with moderately long setae and with long setae in basal part. Distal segment of aedeagus elongate; with long anterior process, one large, raised apical and one horn-shaped apico-posterior tubercles; lateral lobes moderately long, dilated towards apex which is concave.—Female. Proctiger cuneate, pointed apically; dorsal margin, in profile, strongly convex; densely covered with moderately long setae in dorsal part. Subgenital plate cuneate, with moderately long apical process; sparsely covered with moderately long setae in apical half, dorsal margin with few bristles.

Comments.
Russelliana adesmiae
resembles
R. longirostro
, in the presence of the three distinct tubercles on the pronotum, in a forewing membrane with a distinct brown pattern, in a broadly lamellar paramere bearing an apico-anterior process on a pedicel, in a distal segment of the aedeagus bearing a long anterior process, large, raised apical and horn-shaped apico-posterior tubercles and long lateral lobes dilated towards apex, and in a cuneate female proctiger and subglobular plate bearing a short apical process.
R. adesmiae
differs from
R. longirostro
in a shorter rostrum and the presence of a median hump of the paramere.
