Description
Adult ( Figure 5D View Figure 5 ). Wing expanse 13.5–15.0 mm. Head deep grey on vertex, dusted yellow on posterior area and at lateral side, frons yellow-white. Antenna with scape dark brown on dorsal surface, pale white on ventral surface; flagellum dark brown on dorsal surface, bearing yellow-brown annuli, yellow-grey on ventral surface. Labial palpus white; second segment with basal three-quarters grey-brown on outside; third segment black on ventral surface, forming a black line. Thorax and tegula deep grey-brown. Fore wing ground colour grey-brown; costal margin arched, pale ochreous; termen oblique, apex protruding; along apex and termen lying a series of joined elongate spots, forming a thin black fascia; narrow black triangular blotch narrowed gradually from middle of dorsum, reaching three-quarters across wing, edged with yellow-white; discocelluar stigma dark brown, rounded, surrounded by yellow-white; subterminal fascia from near apex to near tornus, edged with yellow along inner side, broad anteriorly; cilia pale white. Hind wing grey, cilia grey-white. Fore leg white, tibia with outer side dark brown or covered densely with brown scales, tarsus scattered with black scales on outside, ringed with brown scales distally; mid- and hind legs yellow-brown tinged with black scales, tarsus ringed with black or brown spots distally. Abdomen pale yellow.
Male genitalia ( Figure 6D View Figure 6 )
Uncus long and slender, approximately parallel sided, ending in point. Gnathos widely Ushaped, lateral side broad at base, narrowed to centre, median portion thin band-like, straight anteriorly. Valva narrow elongate, slightly widened at base, costal and ventral margins nearly parallel sided from basal two-fifths to rounded apex; valva with distal three-fifths setose ventrally, the setae broad, narrow at base, gradually widened to straight apex; costa straight; dorsoproximal process ring-like. Sacculus shorter than costa, narrow, without process. Aedeagus stout, about three-fifths length of valva, distal half obliquely truncate, forming a pointed dorsal process; cornutus made up of a pile of spines.
Female
Unknown.
Diagnosis
This species can be distinguished easily from its congeners by the valva with distal two-fifths parallel sided dorsoventrally, and by the setae on the valva narrow at base, gradually widened to straight apex.
Etymology
The specific name is derived from the Latin prefix set- (= seta), and latus (= broad), referring to the broad setae in the male valva.
