Description
Adult ( Figure 2A View Figure 2 ). Wing expanse 15.0– 16.5 mm. Head yellow-white except greybrown at middle of posterior area. Antenna with scape dark brown on dorsal surface, yellow-white on ventral surface; flagellum lutescent, annulated with fuscous on dorsal surface. Labial palpus white; second segment with basal three-quarters greybrown on outside, bearing a small black spot distally; third segment blackish brown at base and near apex, somewhat tinged with yellow and brown distally. Thorax yellow-grey or deep grey. Tegula yellow-grey. Fore wing ground colour pale greybrown; costal margin gently arched, deep brown basally, becoming yellow-brown to apex; termen truncate, black, bordered by yellow-white along inner side; longitudinal yellow fascia along subcosta vein, between costa and subcosta veins scattered with black scales; two large black dorsal patches edged with yellow-white: first patch irregularly triangular, extending from near base to one-quarter of dorsum, reaching two-thirds across wing, sinuate along outer edge; second patch irregularly squared, from middle to near tornus on dorsum, upward reaching three-quarters across wing, its anterior edge concave at middle, outer edge oblique slightly, concave inward at basal one-third, inner edge nearly straight; longitudinal short black stripe situated between R 1 to R 2 at distal; cilia with basal half grey, distal half grey-white. Hind wing grey-brown; cilia grey basally, grey-white distally. Fore leg white, tibia deep brown on outside, tarsus fuscous on outside at base, with black or light brown rings distally; midleg white, with fuscous spot; hind leg pale yellow to white, with brown spots on tibia. Abdomen grey-brown on dorsal surface, grey-white on ventral surface.
Male genitalia ( Figure 3A View Figure 3 )
Uncus wide at base, slowly narrowed to middle, then sharply narrowed to acute apex. Gnathos band-shaped, sclerotized laterally, weakly sclerotized medially. Valva short and broad, more or less triangular, rounded at apex; costa slightly arched, somewhat concave at base; dorsoproximal process expanded in cuneiform, with setae. Sacculus narrow and sclerotized, longer than costa, with a triangular dorsal process beyond middle, an apical process directing upward not reaching one-third width of valva; dorsal edge between the two processes dentate and strongly sclerotized. Juxta round shield-like, lateral lobe setose. Aedeagus stout, approximately four-fifths length of valva; cornutus consisting of a group of large spines, placed distally.
Female
Unknown.
Diagnosis
This species resembles E. elephantias Meyrick in fore wing pattern, but can be distinguished by the fore wing with the squared black patch concave at basal one-third on outer edge; the sacculus with a small dorsal process beyond middle, and the distal process not exceeding one-third width of valva. In E. elephantias Meyrick , the rectangular patch is not concave at outer edge, the sacculus is concave inward at middle dorsally, and the distal process reaches one-third width of valva.
Etymology
The specific name is from the type locality.
