Adult habitus. General color pale brown but details are obscured by the teneral specimen condition.

Male. Forewing length 25 mm. Hemitergal lobes slender, finger-like with few scattered sensilla basiconica on inner margins near base and at apex ( Figs. 43-44 ). Tergum 9 slightly produced mesally and bearing a mesal patch of more than 50 sensilla basiconica. Hair brushes present on sterna 4-7. Aedeagus membranous, more or less cylindrical but expanded in distal third; armature consists of a dorsal patch of minute to small triangular spines located on apical half of sac ( Fig. 46 ); largest spines located basally except for an additional grouping of fine spines narrowly separated from main patch. Venter of sac without armature.

Female. Forewing length 31 mm. Subgenital plate a moderate size, broadly triangular process projecting over basal third to half of sternum 9 ( Fig. 45 ).

Egg. Outline oval, collar short, wide and surrounded basally by an irregular series of pores extending under rim of collar. Chorion rather uniformly and coarsely punctate throughout; ca. 18 rows of pits visible in lateral aspect with ca. 10-11 pits per row above micropylar line and ca. 9 pits per row below line ( Figs. 80-81 ).

Larva. Unknown.

Etymology. The species name refers to the rather uniformly pitted egg chorion.

Diagnosis. This species is most easily distinguished from Thai and Vietnamese congeners by the uniformly pitted egg chorion. Among species with longer, more slender hemiterga, the males are distinctive by virtue of the absence of ventral armature on the aedeagal sac ( Fig. 46 ).
