Diagnosis. Clunium with a row of denticles over the area of the epiproct (Fig. 40). Hypandrium broad; posterolateral corners projected posteriorly into short, stout, blunt ended, papillose protuberances, the posterior border between them straight, bearing a field of papillae (Fig. 42). Phallosome fused anteriorly, aedeagal arms ending in two projections, the inner one large and acuminate, the outer one short and blunt ended (Fig. 41); external parameres sigmoid and articulated next the outer projection of the aedeagal arms.

Color (in 80% ethanol). Body reddish brown. Forewing pattern (Fig. 38), with pterostigma darker and spots over most cells. Hindwing hyaline (Fig. 39). Veins brown. Hypandrium with pigmented band along anterior border (Fig. 42).

Morphology. As in diagnosis plus the following: pterostigma anteriorly narrow, posteriorly wide, slightly projected towards Rs; veins Rs and M diverging from a point, sides of areola postica slightly convex, crossvein from apex of areola postica to M, short (Fig. 38). Paraprocts slender, with a pigmented anterior “handle” articulated to clunium, and a posterior slender prong; sensory fields with 18–19 trichobothria on basal rosettes (Fig. 40). Epiproct trapeziform, bearing, next to posterior border, a slender, transverse, sclerotized band (Fig. 42).
