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) 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, 185) 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.

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. Comments.
