Diagnosis. Body light yellow to light green when alive and whitish when preserved in alcohol. Tergum ten of males with two median patches of sensilla basiconica. Penial armature is distinctly enlarged at the base in lateral view. Penial hooks of the aedeagus are long as the tube with the apex turned medially. Female sternum eight rounded on the posterior margin.

Redescription of male. Neotype (pres. desig.), male. Light yellow in life, light yellow to whitish when preserved in alcohol. Body ( Fig. 1 ) 8.8 mm long. Head ( Fig. 4 ) light yellow, 1.0 mm long, 1.7 mm wide; frons with slightly “M”-shaped conspicuous spots in the same color, more distinct in lateral view, between the base of the antennae and anterior to the ocelli; ocelli separated by twice their width; maxillary and labial palpi light yellow on the base, slightly brown on the apex; scape, pedicel, and flagellum light yellow. Pronotum ( Fig. 4 ) uniformly light yellow, slightly narrower than head. Meso– and metanotum with pale yellow protuberances. Legs, including coxae, femora and tibiae, uniformly pale yellow. Forewings with Rs, r-m and CuA veins dark brown ( Fig. 5 ). Crossveins r 1 -rs and r-m aligned on fore and hindwings forming a cross. Abdomen light yellow. Cerci light yellow with lateral bristles longest. Sternum nine ( Fig. 8 ) wider than long, lateral bristles longest, posterior margin produced into a rounded lobe slightly oblique in lateral view. Hammer ( Figs. 11–12 ) rounded, produced as a callosity, slightly oblique in lateral view. Paraproct with prominent, but blunt subterminal spine ( Fig. 12 ). Tergum ten ( Fig. 9 ) with two patches of sensilla basiconica. Penial armature the length of tube base, their acute tips crossing medially ( Figs.14–15 ). Penial tube base distinctly dilated in lateral view ( Fig. 16 ).

Female. Originally associated by species authors is maintained (described with subgenital plate covering half of sternum ten, margin entire) ( Fig. 16 ).

Variation. Length of male 8.2–10.0 mm; forewing 9.2–10.0 mm long, 3.1–3.4 mm wide; hindwing 7.7– 8.8 mm long, 3.4–3.7 mm wide; crossveins r 1 -rs and r-m aligned on fore and hindwings forming a cross.

Distribution. Amazonas (Manaus); Pará (Rodovia Belém-Brasília, km 90).
