Diagnosis. Adult ( Fig. 18–20 View FIGURES 17 – 24 ). Wingspan 35–38 mm. Similar to B. prasina , but differs by smaller size, somewhat narrower and acute shape of forewing and less bright green of ground colour. Wing pattern represents half-filled dark-brown subbasal field, prominent brown patch in costal area, black-brown subapical-apical and subtornal marks and by blackish, less expressed than in B. prasina antemedial line, diffused blackish medial line, and thin postmedial line; terminal line as a row of separated black streaks; cilia brown, yellowish opposite veins.

Male genitalia ( Fig. 38 View FIGURES 38 – 40 ). Uncus similar to B. prasina , but thicker, solid; valva more rounded and stronger sclerotised compared B. prasina , with huge basal coremata; clasper and harpe stronger than in B. prasina , harpe bifurcate, with short medial extension. Aedeagus weakly sclerotised dorsally, with carina formed by two sclerotised, but not scobinate bands; vesica basally bulbous, with patch of 17–18 cornuti on basal diverticula, and with cluster of moderate small spines in joining with ventral branch of carina.

Female genitalia ( Fig. 49 View FIGURES 46 – 52 ). In the the female genitalia antrum well formed, one third long as in B. prasina , not split; ductus bursae very short, slightly sclerotised and ribbed in joining with corpus bursae; the late sack-like, with extension in caudal part, not sclerotised and ribbed in caudal part, as B. prasina .

Distribution and bionomics. Malaysia, Borneo (Kalimantan, Timor), Brunei (Seria, Ulu Temburong), Indonesia (Sumatra), Philippines (Mindanao I.).
