Argentina (Río Negro), Chile (IV–V, VII–IX Regions). Comments. Russelliana fabianae resembles R. viscosae in a forewing with a yellow membrane, broadest in the middle, with a strongly curved vein C+Sc medially, in a broadly lamellar paramere bearing a short apicoanterior process lacking a pedicel, in an anteriorly strongly inflated distal segment of the aedeagus bearing a hornshaped apico-posterior tubercle and short lateral lobes with an entire apical margin, in a female proctiger with a convex dorsal margin strongly indented subapically, and a subglobular subgenital plate bearing an apical process. R. fabianae differs from R. viscosae in a longer antenna and the presence of surface spinules in all cells of the forewing membrane. Russelliana globosa sp. nov. (Figs 9 B, 12I, J, 17H, 22H, 27E, 31G) Material examined. Holotype ♂: Argentina : Province Chubut, South Ameghino dam, 5.xi.1990 (L. E. Peña) (NHMB, on slide). Paratypes: Argentina : 1 ♂, 4 ♀, same as holotype (L. E. Peña) (NHMB, dry, on slide, 70 % ethanol). Description. Coloration. Dimorphic, male slightly darker, general body colour brown; female slightly lighter, general body colour yellow to brownish, forewing pattern paler than in males. Head including genal processes pale yellow to brownish; clypeus brown. Eyes brown, ocelli pale yellow. Antenna yellow, segments 4–8 with dark brown apices, segments 9–10 entirely dark brown. Pronotum pale yellow, often dark brown in the middle; mesopraescutum yellow, often with two brownish patches along the fore margin; mesoscutum yellow, often with four broad and, in the middle, one narrow brownish longitudinal stripes; mesoscutellum yellow along the margin, often dark brown in the middle. Metanotum yellow to dark brown. Forewing with whitish to dark brown veins and membrane with distinct pale to dark brown pattern different in males and females. Male forewing membrane with dark brown pattern consisting of confluent dots and patches, stretching from apical part of costal vein to the middle of cell cu1 forming transverse marginal band leaving light areas in cells r2, m1 and m2, continuing along vein Cu1a, stretching from apical part of vein Cu1b to median part of vein C+Sc; membrane between bands colourless, with brown dots varying in size and number scattered over entire surface. Female forewing membrane with pale to dark brown pattern consisting of distinct transverse band, leaving light areas in cells r1, r2, m1 and m2, frequently confluent dots, forming variable, usually lighter patches varying in size and number scattered over entire surface of the wing, and patch along vein Cu1b. Legs pale yellow to brownish, sometimes with darker femora, meracanthus of metacoxa pale yellow. Abdomen pale yellow to brown, lighter ventrally. Male terminalia brown. Female terminalia yellow to brown, proctiger dark in apical third, subgenital plate lighter than proctiger. Structure. Head, in profile, weakly inclined from longitudinal body axis (<45°). Vertex trapezoidal, flat with indented foveae, anteriorly produced into transverse lobe on either side of mid-line, hind margin around lateral ocelli not raised, covered with short 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 very dense, present in all cells, leaving no spinule-free stripes along the veins, forming transverse rows, less developed on unpigmented areas; radular spinules not pronounced. Metatibia with 6 apical spurs. Terminalia. Male. Proctiger barrel-shaped; sparsely covered with moderately long setae in apical two thirds. Subgenital plate elongate; with sparsely spaced long setae restricted to median part. Paramere shortly lamellar; with long recurved hook-shaped apico-anterior process on pedicel, broadly rounded apico-posterior lobe with apically sclerotised median tooth; lobe situated exterior to process; both process and lobe of subequal length; outer face sparsely covered with moderately long setae mostly in apical half, inner face covered with long thick bristles anteriorly and apically. Distal segment of aedeagus moderately elongate, broadly, evenly expanding towards apex; with one small apico-posterior tubercle; lateral lobes long, tubular and with frayed apical margin.—Female. Proctiger subglobular, pointed apically; dorsal margin, in profile, strongly bent downwards; sparsely covered with moderately long setae in apical half dorsally. Subgenital plate globular, strongly bulged, broadly rounded apically; densely covered with long setae in apical part, dorsal margin with a row of bristles. Host-plant. Unknown. Distribution. Argentina (Chubut). Derivation of name. From Latin globus = sphere referring to the globular female subgenital plate. Comments. Russelliana globosa resembles R. adelpha and nolanae see comments under R. adelpha . R. globosa differs from the two species in a less extensive pattern on the male forewing, a distal segment of the aedeagus with longer lateral lobes with subparallel sides, a subglobular female proctiger and globular subgenital plate lacking an apical process. : Published as part of Serbina, Liliya & Burckhardt, Daniel, 2017, Systematics, biogeography and host-plant relationships of the Neotropical jumping plant-louse genus Russelliana (Hemiptera: Psylloidea), pp. 1-114 in Zootaxa 4266 (1) on pages 29-31, DOI: 10.5281/zenodo.575325 : {"references": ["Burckhardt, D.

Proctiger cuneate, subacute apically; dorsal margin, in profile, convex, strongly indented subapically; densely covered with long setae. Subgenital plate subglobular, with moderately long apical process; densely covered with moderately long setae in apical half and with long setae along ventral margin, dorsal margin with a row of bristles. Host-plant. Fabiana imbricata Ruiz & Pav. (Solanaceae). Distribution. Reported from Argentina (Chubut, Río Negro), Chile (VII Region) (Burckhardt 1987). Material examined. Argentina (Río Negro), Chile (IV–V, VII–IX Regions). Comments. Russelliana fabianae resembles R. viscosae in a forewing with a yellow membrane, broadest in the middle, with a strongly curved vein C+Sc medially, in a broadly lamellar paramere bearing a short apicoanterior process lacking a pedicel, in an anteriorly strongly inflated distal segment of the aedeagus bearing a hornshaped apico-posterior tubercle and short lateral lobes with an entire apical margin, in a female proctiger with a convex dorsal margin strongly indented subapically, and a subglobular subgenital plate bearing an apical process. R. fabianae differs from R. viscosae in a longer antenna and the presence of surface spinules in all cells of the forewing membrane. Russelliana globosa sp. nov. (Figs 9 B, 12I, J, 17H, 22H, 27E, 31G) Material examined. Holotype ♂: Argentina : Province Chubut, South Ameghino dam, 5.xi.1990 (L. E. Peña) (NHMB, on slide). Paratypes: Argentina : 1 ♂, 4 ♀, same as holotype (L. E. Peña) (NHMB, dry, on slide, 70 % ethanol). Description. Coloration. Dimorphic, male slightly darker, general body colour brown; female slightly lighter, general body colour yellow to brownish, forewing pattern paler than in males. Head including genal processes pale yellow to brownish; clypeus brown. Eyes brown, ocelli pale yellow. Antenna yellow, segments 4–8 with dark brown apices, segments 9–10 entirely dark brown. Pronotum pale yellow, often dark brown in the middle; mesopraescutum yellow, often with two brownish patches along the fore margin; mesoscutum yellow, often with four broad and, in the middle, one narrow brownish longitudinal stripes; mesoscutellum yellow along the margin, often dark brown in the middle. Metanotum yellow to dark brown. Forewing with whitish to dark brown veins and membrane with distinct pale to dark brown pattern different in males and females. Male forewing membrane with dark brown pattern consisting of confluent dots and patches, stretching from apical part of costal vein to the middle of cell cu1 forming transverse marginal band leaving light areas in cells r2, m1 and m2, continuing along vein Cu1a, stretching from apical part of vein Cu1b to median part of vein C+Sc; membrane between bands colourless, with brown dots varying in size and number scattered over entire surface. Female forewing membrane with pale to dark brown pattern consisting of distinct transverse band, leaving light areas in cells r1, r2, m1 and m2, frequently confluent dots, forming variable, usually lighter patches varying in size and number scattered over entire surface of the wing, and patch along vein Cu1b. Legs pale yellow to brownish, sometimes with darker femora, meracanthus of metacoxa pale yellow. Abdomen pale yellow to brown, lighter ventrally. Male terminalia brown. Female terminalia yellow to brown, proctiger dark in apical third, subgenital plate lighter than proctiger. Structure. Head, in profile, weakly inclined from longitudinal body axis (<45°). Vertex trapezoidal, flat with indented foveae, anteriorly produced into transverse lobe on either side of mid-line, hind margin around lateral ocelli not raised, covered with short 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 very dense, present in all cells, leaving no spinule-free stripes along the veins, forming transverse rows, less developed on unpigmented areas; radular spinules not pronounced. Metatibia with 6 apical spurs. Terminalia. Male. Proctiger barrel-shaped; sparsely covered with moderately long setae in apical two thirds. Subgenital plate elongate; with sparsely spaced long setae restricted to median part. Paramere shortly lamellar; with long recurved hook-shaped apico-anterior process on pedicel, broadly rounded apico-posterior lobe with apically sclerotised median tooth; lobe situated exterior to process; both process and lobe of subequal length; outer face sparsely covered with moderately long setae mostly in apical half, inner face covered with long thick bristles anteriorly and apically. Distal segment of aedeagus moderately elongate, broadly, evenly expanding towards apex; with one small apico-posterior tubercle; lateral lobes long, tubular and with frayed apical margin.—Female. Proctiger subglobular, pointed apically; dorsal margin, in profile, strongly bent downwards; sparsely covered with moderately long setae in apical half dorsally. Subgenital plate globular, strongly bulged, broadly rounded apically; densely covered with long setae in apical part, dorsal margin with a row of bristles. Host-plant. Unknown. Distribution. Argentina (Chubut). Derivation of name. From Latin globus = sphere referring to the globular female subgenital plate. Comments. Russelliana globosa resembles R. adelpha and nolanae see comments under R. adelpha . R. globosa differs from the two species in a less extensive pattern on the male forewing, a distal segment of the aedeagus with longer lateral lobes with subparallel sides, a subglobular female proctiger and globular subgenital plate lacking an apical process. : Published as part of Serbina, Liliya & Burckhardt, Daniel, 2017, Systematics, biogeography and host-plant relationships of the Neotropical jumping plant-louse genus Russelliana (Hemiptera: Psylloidea), pp. 1-114 in Zootaxa 4266 (1) on pages 29-31, DOI: 10.5281/zenodo.575325 : {"references": ["Burckhardt, D.
