Head and thorax usually multi-coloured, ground colour light orange-yellow, dark orange to dark brown. Vertex sometimes irregularly lighter posteriorly. Gena usually brownish to dark brown anteriorly and ventrally; genal process lighter than rest of gena. Eye grey to dark red; ocelli orange. Antenna light yellow, segments 1–2 darker. Clypeus yellow to medium brown, lighter medially and darker along edges; rostrum light yellow to yellowish-orange. Thorax usually brownish to dark brown, with margins of sclerites darker. Mesopraescutum usually with median light to white irregular transversal marking and posterior half irregularly coloured. Forewing colourless to yellowish, yellow around Cu 1b and slightly around rest of veins apically; veins light yellowish-brown; pterostigma lighter to slightly darker than veins. Hindwing colourless. Fore- and midleg dark yellow with femora brown and tarsi usually darker, hindleg light yellow with femur brown. Abdomen yellow, dark orange to medium brown, medium to dark brown ventrally; intersegmental membranes light to dark yellow; spiracular sclerites concolorous with tergites. Male terminalia irregularly dark yellow to medium brown. Female terminalia irregularly dark yellow to medium brown, usually darker apically, sometimes darker basally and around anus.

Structure. Body length ♁ 1.9–2.4 mm (2.24± 0.21 mm), ♀ 2.0– 2.6 mm (2.38± 0.23 mm) (5 ♁, 5 ♀). Genal process ( Fig. 155 View FIGURES 148–162 ) expanded, irregularly narrowing towards subacute, narrowly or broadly rounded apex, 0.5–0.6 times as long as vertex along midline.Antenna 2.3 times as long as head width; longest terminal seta slightly shorter than segment 10. Apical labium segment 0.2 times longer than head width and 0.7–0.8 times longer than median segment. Forewing ( Fig. 37 View FIGURES 35–37 , 185 View FIGURES 183–192 ) 2.8–3.1 times as long as head width, 1.9–2.5 times as long as wide, obovoid or subrhomboidal narrowly or slightly broadly rounded apically; vein M+Cu 1 0.3–0.4 times as long as Cu 1; ratio a/b 1.6–1.9; ratio c/d 0.7–0.9; ratio e/f 0.6–0.7. Surface spinules moderately spaced, forming rhomboids ( Fig. 39 View FIGURES 38–43 ); covering apical half or two thirds of cell r 1, apical half or apex of cell r 2, around radular areas of cells m 1, m 2 and cu 1 (sometimes much reduced), m 2 basally, and most of cell cu 2; leaving spinule-free spaces along veins ( Fig. 42 View FIGURES 38–43 ). Radular spinules present in cell r 2, sometimes inconspicuous. Metatibia 0.7–0.8 times as long as head width.

Terminalia. Male. Proctiger, in lateral view, 0.4 times as long as head width; with short, blunt, weakly downcurved posterior lobe. Paramere, in lateral view ( Figs 259 View FIGURES 256–264 ‾261) 0.8–0.9 times as long as proctiger; clavate, moder-ately expanded apically; anterior margin expanded and broadly or narrowly rounded in apical third; posterior margin rounded and strongly expanded in apical third, weakly to strongly convex in basal two thirds; apex somewhat straight, more expanded posteriorly than anteriorly, with sclerotised ridge subposteriorly ( Fig. 260 View FIGURES 256–264 ); inner surface ( Fig. 260 View FIGURES 256–264 ) covered with short setae, longer basally and along posterior margin, with row of thick setae along apical anterior margin, several thick setae below sclerotised ridge, and group of stout setae on apical posterior margin; in dorsal view ( Fig. 305 View FIGURES 283–312 ), sclerotised ridge irregularly subrectangular, slightly larger anteriorly, bearing posterior tooth. Aedeagus ( Fig. 261 View FIGURES 256–264 ) complex unipartite; in lateral view, dorsal lobe obovoid; ventral process weakly upturned, with apical expansion larger than dorsal lobe, subglobular, bearing short, conical tubercle.—Female (Fig. 335). Proctiger, in lateral view, 1.0–1.2 times as long as head width; dorsal outline weakly to strongly concave distal to circumanal ring, apical extension almost straight to sinuous, apex slightly to moderately upturned, obliquely rounded; circumanal ring 0.3 times as long as proctiger. Subgenital plate, in lateral view, 0.6 times as long as proctiger; apex well-developed; ventral outline almost straight to slightly sinuous, sometimes slightly notched submedially or subapically; covered with medium long setae in median third and ventrally throughout, short setae in apical third, long setae at apex, and group of long setae on dorsum subapically, with seta-free patch subapically; in ventral view ( Fig. 365 View FIGURES 363–372 ), lateral margins somewhat unevenly strongly narrowing submedially towards narrow, rounded apex.

Measurements (in mm) (4 ♁, 3 ♀). HW ♁ 0.59–0.61 (0.6±0.01), ♀ 0.63–0.65 (0.64±0.01); AL ♁ 1.37–1.41 (1.39±0.03), ♀ 1.44–1.49 (1.47±0.03); LAB2 ♁ 0.15–0.16 (0.15±0.01), ♀ 0.16–0.18 (0.17±0.01); LAB3 ♁ 0.11– 0.12 (0.11±0.01), ♀ 0.11–0.12 (0.11±0.01); FL ♁ 1.68–1.82 (1.76±0.07), ♀ 1.90–1.99 (1.94±0.05); TL ♁ 0.44– 0.48 (0.46±0.02), ♀ 0.46–0.48 (0.47±0.01); MP 0.24–0.26 (0.25±0.01); PL 0.20–0.21 (0.20±0.01); DL 0.27–0.28 (0.27±0.01); FP 0.67–0.74 (0.7±0.04).

Etymology. Named after its host-plant genus, Periandra   .

Distribution. Brazil: Goiás, Minas Gerais, Paraná.

Host-plant. Periandra mediterranea (Vell.) Taub.   (Leguminosae, Papilionoideae   , Phaseoleae   ). A small series including immatures was collected on Desmodium adscendens (Sw.) DC.   (Leguminosae, Papilionoideae   , Desmodieae   ) which is not a host; Periandra   and Desmodium   can grow together which makes it, sometimes, difficult to determine which plant is the psyllid host.

Habitat. Araucaria   forest, transitional forest, Baccharis   scrub, Cerrado, transition from riparian to Cerrado vegetation, transitional Araucaria   /Atlantic forest, parks, Atlantic forest.
