Sterigma moderate, with more or less distinct anteostial part, often forming a proximal cup; postial plate often elongate, or slender extending laterally to connect apophyses anteriors. Bursa copulatrix with well differentiated ductus bursae.

Some genera widely distributed (Razowski, 2003). Wingspan of adult is about 10-25mm in average. Forewings broad, costa often convex, with or without costal fold in males; occasionally refractive markings present in yellowish, reddish, and rusty brown tones on the forewing. Venation, chorda rarely present; M-stem ill-defined or absent. Male genitalia. Tegumen usually large; uncus species-specific, with subterminal brush. Socius usually membranous, drooping hairy. Gnathos arm and terminal plate well developed. Vinculum fully developed, usually with lateral folds. Valva more or less elongate; costa variable developed, well sclerotized more or less long, or atrophied; sacculus simple to variably armed, often with free end; caudal area of valva membranous, often with outer pocket resembling brachoila, or strongly elongate. Aedeagus small to modrate; coecum penis well developed, rarely strongly reduced; caulis distinct, often large; cornuti, a few fixed capitate and/or a bunch deciduous spines. Female genitalia. Sterigma moderate, with more or less distinct anteostial part, often forming a proximal cup; postial plate often elongate, or slender extending laterally to connect apophyses anteriors. Bursa copulatrix with well differentiated ductus bursae. Signum in dagger (plate) shape, often with capitulum, or reduced. I. MATERIAL AND METHODS The types and other specimens examined were collected by using light traps in five national parks in the northern part of Vietnam (Fig. 1) from 2004 to 2010 and now being deposited in .
