Thorax entirely brown and covered by inconspicuous setae dorsally. Metascutellar horn small, basally wide, blunt apically. Forewing light brown, veins yellow, apically brown to forewing margin, central part of vein A brown; pterostigm a white. Forewing with short setae on veins (vein Rs with 16–20 setae); Rs vein marginally curved throughout. Surface spinules present in all cells of forewing; radular spinules lacking.

Material examined. HOLOTYPE, Philippines: Palawan, Mt St Paul N. P., Sabang- Cabayugan road, 25 January 1988,? Convolvulaceae (J. H. Martin) (BMNH) . Dry mounted.

PARATYPES. Philippines: 6, 24, 11 larvae, same data as holotype ( BMNH, NHMB). Dry and slide mounted .
