Forewing oblong-oval, narrowly rounded apically; vein C+Sc weakly curved, pterostigma long, vein Rs almost straight apically; vein M about as long as 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 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 relatively densely spaced moderately long setae and with long setae along ventral margin. Paramere irregularly subtrapezoidal, curved with median convexity apically; with hook-shaped apico-anterior process on short pedicel, apically sclerotised median tooth and bulged apico-posterior lobe; both process and lobe of subequal length; outer face sparsely covered with moderately long setae mostly in apical half, inner face densely covered with short to moderately long setae. Distal segment of aedeagus moderately elongate, weakly expanding towards apex; with moderately long anterior process, one apical, horn-shaped, and one apico-posterior tubercles, the latter being curved forward; lateral lobes long, dilated towards apex which is concave.—Female. Proctiger cuneate, pointed apically; dorsal margin, in profile, sinuous, with subapical indentation; densely covered with short setae. Subgenital plate cuneate, with short apical process; sparsely covered with moderately long setae, dorsal margin with few bristles. Host-plants.Polyphagous, confirmed hosts are Alternanthera ficoidea(L.) Sm. ( Amaranthaceae), Baccharis lycioidesJ.Rémy, B. zoellneriF.H.Hellw. ssp. minorF.H.Hellw., Helenium aromaticum(Hook.)

Distribution.The species is native to the Andes Region (Central and Western Argentina, Bolivia, Far Northern–Southern Chileand Peru) and presumably was introduced into eastern South America (Eastern Argentina, Southern Brazil, Uruguay) ( Tuthill 1959; Burckhardt 1987; Serbina et al.2015).
Comments.The collections of Russelliana solanicolafrom the MHNG and NHMB include a large number (few hundreds) of dry and slide mounted specimens, and those preserved in 70 % ethanol. Some specimens assigned to R. solanicolain Serbina et al.(2015)belong to other closely related species, R. brevigenis sp. nov., R. caunda sp. nov.and R. didyma sp. nov.For more details on the locality data, see the descriptions of R. brevigenis sp. nov., R. caunda sp. nov.and R. didyma sp. nov. Russelliana solanicolaresembles R. chorizanthis, disparilis, nigra, rutilaand similis; see comments under R. chorizanthis. R. solanicoladiffers from R. disparilisand nigrain a median convexity of the apical margin of the paramere, from R. disparilisand similisin the presence of surface spinules in the apical part of the forewing membrane, and from R. nigraand rutilain a colourless forewing membrane. It differs from R. chorizanthisin a shorter female terminalia, and from R. disparilisin a smaller apico-posterior lobe of the paramere and an apically subacute anterior process of the distal segment of the aedeagus.

Vertex subtrapezoidal, flat with indented foveae, anteriorly produced into transverse lobe on either side of mid-line, with slightly raised hind margin around lateral ocelli, covered with microscopical setae; genal processes conical, relatively slender, subacute apically, shorter than vertex, covered with short setae. Forewing oblong-oval, narrowly rounded apically; vein C+Sc weakly curved, pterostigma long, vein Rs almost straight apically; vein M about as long as either of veins M1+2 and M3+4; surface spinules absent; radular spinules covering triangular areas along the margin of cells r2, m1, m2 and cu1. Metatibia with 4–6 apical spurs. Terminalia. Male. Proctiger tubular; sparsely covered with moderately long setae mostly in posterior part. Subgenital plate short, subglobular; with sparsely spaced long setae. Paramere narrowly lamellar with constricted base, weakly sinuous apically, posterior margin curved; with short 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 short setae. Distal segment of aedeagus moderately elongate, weakly expanding towards apex; with anterior process slightly directed upwards, situated almost in the middle of distal segment and with one short 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, almost straight; sparsely covered with relatively short setae in apical half. Subgenital plate subglobular, with short apical process; sparsely covered with moderately long setae in apical part, dorsal margin with a bristle. Host-plant. Tetraglochin alatum(Gillies ex Hook. & Arn.) Kuntze (Rosaceae).
Distribution. Argentina( Mendoza), Chile(V Region). Derivation of name.Named after its host Tetraglochin.
Comments. Russelliana tetraglochinresembles some Adesmiafeeding species in a narrowly lamellar paramere bearing an apico-anterior process lacking a pedicel, and in a distal segment of the aedaegus bearing two small apico-posterior tubercles. It differs from most of Adesmia-feeders in the absence of a brown pattern on the forewing membrane, and a subglobular female subgenital plate.
