Description. Male habitus (Figs 37–39). Head, thorax and abdomen brown. Thorax bears dorsal triangular dark brown spot with pale center; dark brown line goes from the spot towards head. Forewing length: 14–15 mm; wingspan: 29–31 mm. Wing oval-shaped, apex obtuse, external margin slightly waved with concavity between CuA 2 and 1A. Pattern marmorate, orangish brown and brown with multiplied light and dark antemedial, postmedial and external crenulate lines; and blackish discal dot on R-Cu cell outer margin. Cilia brown. Hindwing oval-shaped, external margin rounded, slightly waved. Main color yellowish or reddish brown, darkens caudally. Cilia brown. Male genitalia (Figs 40–42). Tegumen band-shaped, bears two short projections with sharpen apexes and covered with chaetae along. Vinculum thin, ventrally widened into cup-like form. Sacculus elongated, finger-shaped with blunt apex. Cucullus tuber-like, covered with chaetae. Juxta a tiny plate fused with aedeagus. Aedeagus cylindrical with small uneven dorsal sclerotized field right by vesica and ventral c-shaped long basal spur with blunt apex. Vesica bag-shaped with two chambers: smaller lateral and bigger main, both covered with tiny denticles; main one bears cornutus formed by several fused smaller cornuti.

Biology. Adults were observed and collected in November, December and February. The only known habitat is tropical moist broadleaf forests with rare mosaic grassland patches, the elevation is around 100 m above sea-level. One paratype male was collected on the border between forest and grassland in an area of one hectare using an auto-trap (Figs 53–55). The larval foodplant remains unknown.
