Diagnosis. This species rather to the fletcherata species group ( Bolte 1990). It is externally most similar to the Chinese E. inopinata Vojnits, 1984 ( Mironov & Galsworthy 2014), but the discal dots on the fore wings are larger. The male genitalia are best distinguished from those of other species by the combination of the shape of the valve with a broadly sclerotized and rounded saccular projection, the cornuti on the vesica and the shape of the eighth sternite.

Description. Adults. ( Figs 1 , 15 ). Male. Wingspan 22.0 mm, fore wing 12.0 mm. Head and notum covered with whitish scales. Fore wing rather elongate and narrow. Ground colour brownish grey; costal margin with four black costal blotches; transverse lines not clearly visible; subterminal line indented, whitish, forming a whitish tornal spot; terminal area darker near apex; terminal line black, interrupted by veins; discal dot large, black, ovoid. Hind wing ovoid, pale brownish-grey; transverse lines inconspicuous, discal spot small, black, rounded. Fringe chequered with brownish-grey and pale dirty whitish.

Male genitalia ( Fig. 21 ). Uncus stout, rather short, biapical. Valve with sinuate dorsal margin, and broadly sclerotized sacculus, which forms a broadly rounded projection at the middle of the valve with broadly rounded apex. Vinculum rather short and medium width, semicircular. Papillae on the anterior arms of the labides comparatively short, narrow, covered with normal-sized setae. Aedeagus tapered to anterior end. Vesica armed with a patch of three horn-like cornuti, one separate horn-like cornutus near the apical part and a folded, irregular cornutus near ductus ejaculatorius base. Sternite A8 peg-like, tapered to posterior end, with two broad parallel arms with spineshaped apices; apical hollow deep and narrow; basal hollow shallow; two basal lobes less sclerotized than remainder of sternite.

Female. Unknown.

Bionomy. Host plant unknown. The holotype was collected by light in May at an elevation of 2900–3000 m ( Fig. 35 ).

Distribution. China. Known from Qinghai province.

Etymology. This species is named in honour of the English lepidopterist, naturalist and former Ambassador to the People’s Republic of China from 1997 to 2002 Sir Anthony Charles Galsworthy (London, Great Britain).
