Crown with transverse apical and preapical band sometimes joined by black longitudinal stripe along midline, pronotum with white median area partly or completely enclosed by brown or black pigment, mesonotum with basal triangles brown or black and more extensive dark pigment sometimes present (Fig. 27A, D). Face with dorsal, median and ventral transverse black bands variably developed (Fig. 27E).

Morphology. Head slightly narrower than pronotum, subconical, anterior margin rounded to face, acutely angled (Fig. 27A, B, D). Vertex nearly as long as 2x width between eyes (Fig. 27A, D). Anteclypeus nearly parallelsided, extending slightly beyond normal curve of genae (Fig. 27E). Pronotum median length slightly shorter than median length of crown. Mesonotum and scutellum together slightly shorter than pronotum (Fig. 27A, D). Forewing macropterous, usually exposing apex of abdomen in female, with supernumerary crossveins (Fig. 27A, B, D).
Male genitalia. Pygofer side long, with few macrosetae dorsally, dorsal margin nearly straight posteriorly, posterior margin rounded (Fig. 28A). Subgenital plate slightly convex laterally, macrosetae uniseriate laterally (Fig. 28C). Style apophysis attenuated, laterallylaterally curved, preapicalpreapical lobelobe roundedrounded (Fig. 28D). ConnectiveConnectiveConnective Y-shaped, stemstemstem broadened distally and nearly as long as arms (Fig. 28E). Aedeagal shaft bent strongly dorsad near base, relatively short and sinuate in lateral view with apex attenuated, parallel to aedeagal base, slightly widened preapically then tapered to sharp point in dorsal view, with subapical membranous area (Fig. 28 F–H).
Female. Hind margin of seventh sternum shallowly concave (Fig. 27F).
