Body medium sized, depressed. Ground color yellow, orange to brown with dark patches and smoky areas, forming symmetrical pattern. Head and pronotum with some patches or spots along fore margin, midline and hind margin of pronotum grey bordered with dark brown. Forewing with irregular orange, brown and smoky areas, brochosome field distinct. Crown fore margin rounded or angulately produced medially, head as wide as or slightly wider than pronotum, face flat in profile, anteclypeus of male broad, lorum large. Forewing venation with third apical cell widest and second apical cell narrowest, fourth apical cell not extended to tip of wing, about half length of third, MP''+CuA' straight or slightly curved basally; AA and AP vein distinct. Hind wing venation usual for Erythroneurini , RA vein absent. Male 2S abdominal apodemes long and moderately broad, extended to sternite IV–V. Anal tube appendage stick-like, usually straight, weakly sclerotized. Male genital capsule depressed and well sclerotized, pygofer side with some fine setae on central area or near caudal margin, with or without basolateral macrosetae; dorso-lateral inner ridge well developed; without dorsal and ventral appendages. Subgenital plate short and broad, nearly triangular, with several macrosetae near outer margin, row of marginal microsetae and some microsetae scattered on ventral side. Style stout, apical part lamellate, short to long, usually with distinct subapical extension, preapical lobe cheliform. Connective V-shaped or lamellate, central lobe absent. Aedeagal shaft tubular, with or without dorso-apical lamella; dorsal apodeme usually well developed; preatrium short to long; gonopore terminal. Diagnosis. This genus is very similar to Diomma Motschulsky : both have the body depressed with a distinct dorsal symmetrical color pattern, but Kusala has complete hind wing venation, while the hind wing of Diomma has a reduced submarginal vein and lacks vein CuA’’.
