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.    Russelliana tetraglochin  sp. nov. ( Figs 10I, 15D, 20C, 25C, 29C, 34A)     Materialexamined. Holotype ♂:  Chile: V Region, Province Los Andes,  El Juncal,  2200 m,  24.xii.1998,  Tetraglochin alatum, alpine scrub with low bushes ( D.

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. 1502683741 [151,1282,685,710] Argentina Catamarca 51 52 1 Catamarca 1502683753 [1294,1393,685,710] Argentina Cordoba 51 52 1 Cordoba 1502683788 Argentina La Rioja 51 52 1 La Rioja 1502683779 [226,347,722,746] Argentina Rio Negro 51 52 1 Rio Negro 1502683776 [359,418,721,746] Argentina Salta 51 52 1 Salta 1502683784 [430,538,722,746] Argentina Tucuman 51 52 1 Tucuman 1502683769 [548,880,721,746] Bolivia Chuquisaca 51 52 1 Chuquisaca 1502683780 [892,961,721,746] Bolivia Tarija 51 52 1 Tarija 1502683775 [971,1213,721,746] Brazil Minas Gerais 51 52 1 Minas Gerais 1502683772 [1225,1304,722,746] Brazil Parana 51 52 1 Parana 1502683787 [1316,1432,721,746] Brazil Sao Paulo 51 52 1 Sao Paulo 1502683791 I Region & II Region & El Loa & IV Region & V Region & San Felipe de Aconcagua Chile Valparaiso 51 52 1 Valparaiso 1502683783 VI Region & IX Region Chile Region Metropolitana 51 52 1 Region Metropolitana 1502683762 [151,311,865,890] Peru Ancash 51 52 1 Ancash 1502683774 [323,430,865,890] Peru Arequipa 51 52 1 Arequipa 1502683785 [442,515,866,890] Peru Cusco 51 52 1 Cusco 1502683781 [526,630,866,890] Peru Huanuco 51 52 1 Huanuco 1502683768 [642,704,865,890] Peru Lima 51 52 1 Lima 1502683767 [716,839,866,890] Peru Moquegua 51 52 1 Moquegua 1502683782 BMNH, CASC, FSCA, MHNG, NHMB Brisa de la Pinta Uruguay Tacna 51 52 1 Tacna 1502683777 1983-11-26 1983-11-28 1983-11-26 MHNG L.
