Eyes dark brown ( Fig. 2 ). Face broad; postclypeus beige, darker than anteclypeus; anteclypeus with one single triangular dark marking near bottom and dark apex ( Figs 2, 3, 5 ). Pronotum without markings, with posterior margin concave distinctly ( Figs 1, 4 ). Scutellum with a dark inverted triangular area at bottom medially; scutellar suture distinct ( Figs 1, 4 ). Forewing brownish, with 4th apical cell tiny, semicircular ( Fig. 17 ). Hind wing transparent ( Fig. 16 ).

Male abdominal apodemes bladelike, extending to anterior margin of 4th sternite slightly ( Fig. 11 ).

Male genitalia. Pygofer lobe bifurcated, as in generic description with dorsal and ventral two lobes (dorsal one significantly larger than ventral one); microtrichia near upper caudal margin well developed, 1–2 long fine setae scattered at lower caudal margin of lower lobe ( Fig. 7 ); dorsal pygofer appendage with bifurcated apex and handlike in lateral view ( Fig. 8 ). Subgenital plate expanded near base and apex respectively, central area concave, common in Erythroneurini ( Fig. 10 ). Aedeagal shaft much longer than preatrium and dorsal apodeme, Pipa-like in ventral view, with pair of short processes subapically; dorsal apodeme connected with broad ligament in lateral view; gonopore terminal, ventrad ( Figs 12, 13 ). Connective central lobe absent, stalk short but distinct ( Fig. 14 ). Style with very long and branched apex; preapical lobe small but prominent ( Fig. 15 ).
