Description
Adult ( Figure 5C View Figure 5 ). Wing expanse 13.0– 13.5 mm. Head deep grey-brown, dusty grey laterally, somewhat yellow-white on frons. Antenna with scape dark brown on dorsal surface, pale yellow to yellow on ventral surface; flagellum grey yellow on ventral surface, grey-brown on dorsal surface. Labial palpus with second segment yellowwhite except distal part brown on outer side; third segment pale yellow, black on ventral surface. Thorax and tegula grey black to dark brown. Fore wing ground colour grey-brown; costal margin yellow-brown, straight slightly; termen oblique; a series of elongate deep brown spots along apex and termen; elongate black triangular blotch from dorsum reaching three-quarters width across wing, gradually narrowed upward, edged with yellow-white; discocelluar stigma black, rounded, surrounded by yellow; subterminal fascia extending from before apex to tornus, more or less straight, with yellow-white edge on inner side, anterior portion broad; cilia greywhite. Hind wing grey-brown; cilia grey. Fore leg white, with dispersed brown scales, femur and tibia with outer side grey black, tarsus with basal two-thirds grey black, ringed with brown distally; mid- and hind legs yellow-brown, tibia with dense brown scales on outer surface, tarsus with dense brown scales at basal one-third on outer side, ringed with brown distally. Abdomen clothed with dark brown on dorsal surface, yellow-brown on ventral surface.
Male genitalia ( Figure 6C View Figure 6 )
Uncus long and slender, curved slightly. Gnathos broadly U-shaped, narrowed gradually from base of both side to middle, median portion thin, weakly sclerotized. Valva slightly broad at base, irregularly triangular distally, apex narrowly rounded; costa arched, concave basally; dorsoproximal process expanded in wide ring form. Sacculus about as long as costa, strongly sclerotized, narrowed distally, with a distal process extending outward. Aedeagus short and sturdy, approximately half length of valva, obliquely truncate terminally, forming an apical point dorsally.
Female
Unknown.
Diagnosis
This species is close to E. melanocona (Meyrick) , but distinguishable by the fore wing valva narrowly rounded apically and the dorsoproximal process dilated in a wide ring form. In E. melanocona (Meyrick) , the valva is bluntly rounded apically and the dorsoproximal process dilated in thumb-like form.
Etymology
The specific name is from the type locality.
