Diagnosis. Adult (Figs. 11–13). Wingspan: male, 20–23 mm, female 23–26 mm. This is the most widespread South East Asian Stenoloba species, distributed from Dawna Mts. in south Myanmar, through peninsular Malaysia to Sumatra and Java. Externally it could be confused with S. elegans and S. futioides. It differs from S. elegans by the shape of the reniform and from S. futiodes by the presence of a clear wide shadow in the medial field behind antemedial line. In male genitalia (Fig. 38) it differs from its allies by more developed uncus and the presence of a ring formed by minute cornuti in the base of the vesica. Males have brush organ on the 8 th segment of abdomen (Fig. 51), represented by thin sclerotized ring and very large gland (much larger than in related species), bearing a brush of hairs. In female genitalia (Fig. 62, 63) it differs from S. futioides by larger antrum with broader antevaginal plate.

Distribution. Malayan Peninsula: Myanmar, Malaysia; Indonesia: Sumatra, Java. The species occurs in mountains at elevations of 800–1000 m. Several generations, probably throughout the year.
