Description. Coloration. General colour of body dark brown to black. Head, genal processes and thorax dark brown to black; clypeus black. Eyes red to black, ocelli orange to red. Antenna pale to dirty yellow, segments 1, 9 and 10 entirely black, segment 2 black at base, segments 3–8 with black apices. Forewing with dark brown veins and evenly brown membrane. Legs dirty yellow to brownish, with black femora and distal tarsal segments, meracanthus of metacoxa pale yellow. Abdomen and terminalia brown to black. Female proctiger black in apical third. Teneral specimens orange laterally.

Structure. Head, in profile, moderately to strongly inclined from longitudinal body axis (45–90°). 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, relatively slender and subacute apically, distinctly shorter than vertex, covered with moderately long setae. Forewing oval, broadly, evenly rounded apically; vein C+Sc weakly curved, pterostigma long, vein Rs weakly sinuous, slightly curved to fore margin apically; vein M about as long as either of veins M1+2 and M3+4; surface spinules very dense, present in all cells, leaving very narrow spinule-free stripes along the veins, irregularly spaced; faint in cell c+sc and absent in its basal third; radular spinules covering rounded areas along the margin of cells r2, m1, m2 and cu1. Metatibia with 6–8 apical spurs.

Terminalia. Male. Proctiger tubular; sparsely covered with moderately long setae. Subgenital plate short, subglobular; with sparsely spaced moderately long setae. Paramere irregularly subtrapezoidal; with sickle-shaped apico-anterior process on very short pedicel and slightly bulged, apically sinuous apico-posterior lobe with apically sclerotised median tooth; both process and lobe of subequal length; outer face sparsely covered with moderately long setae mostly in posterior half, inner face densely, evenly covered with long setae. Distal segment of aedeagus moderately elongate, weakly expanding towards apex; with moderately long anterior process, one apical and one apico-posterior tubercles, the latter being curved forward; lateral lobes long, strongly dilated towards apex which is concave.—Female. Proctiger cuneate, pointed apically; dorsal margin, in profile, slightly convex; sparsely covered with relatively short setae. Subgenital plate cuneate, with short apical process; sparsely covered with relatively short setae in apical half, dorsal margin with a row of bristles.

Host-plant. Unknown.

Distribution. Reported from Bolivia (Chuquisaca) ( Burckhardt 1987).

Comments. Russelliana nigra resembles R. chorizanthis , disparilis , rutila , similis and solanicola ; see comments under R. chorizanthis . R. nigra differs from the five species in an evenly brown forewing membrane, from R. chorizanthis , rutila , similis and solanicola in the absence of a median hump of the paramere, and from R. disparilis and similis in the presence of surface spinules in the apical part of the forewing membrane. It differs from R. chorizanthis in a shorter female terminalia, and from R. disparilis in a smaller apico-posterior lobe of the paramere and an apically subacute anterior process of the distal segment of the aedeagus.

Forewing oblong-oval, broadly, unevenly rounded apically; vein C+Sc weakly curved, pterostigma long, vein Rs almost straight apically; vein M longer than either of veins M1+2 and M3+4; surface spinules present in all cells, leaving narrow spinule-free stripes along the veins, sparsely spaced and forming hexagonal pattern; radular spinules covering triangular areas along the margin of cells r2, m1, m2 and cu1. Metatibia with 7 apical spurs.

Terminalia. Male. Proctiger tubular; sparsely covered with moderately long setae. Subgenital plate short, subglobular; with sparsely spaced moderately long setae. Paramere narrowly lamellar, posterior margin slightly convex; with long apico-anterior process lacking pedicel, and apically sclerotised median tooth; outer face sparsely covered with moderately long setae mostly in posterior part, inner face sparsely covered with moderately long setae. Distal segment of aedeagus moderately elongate, expanding towards apex; with short anterior process, one small and one horn-shaped apico-posterior tubercles; lateral lobes moderately long, slightly dilated towards apex which is concave.—Female. Proctiger cuneate, pointed apically; dorsal margin, in profile, almost straight or slightly convex; sparsely covered with moderately long setae. Subgenital plate cuneate, with short apical process; sparsely covered with moderately long setae, dorsal margin with few bristles.

Host-plants. Adesmia argentea Meyen , A. cf. confusa Ulibarri , A. dichotoma Clos , A. cf. glutinosa Hook. & Arn. , A. cf. kingii Phil. and A. cf. pedicellata Hook. & Arn. (Fabaceae) .

Distribution. Chile (III–V Regions, Region Metropolitana).

Derivation of name. From Latin pallidus = pale referring to the pale forewing pattern.

Comments. Russelliana pallida resembles R. longicauda ; see comments under R. longicauda . R. pallida differs from R. longicauda in the presence of surface spinules in the apical part of the forewing membrane, a long apico-anterior process of the paramere, a longer anterior process situated in the apical part of the distal segment of the aedeagus bearing longer lateral lobes, and a shorter female terminalia with a subgenital plate bearing a short apical process.
