Type material. Holotype: ♂, Korea, Chungcheonbuk-do , Goesan , Yeonpung, Wonpung, 30 June 2011, Sora Kim, gen. slide no. SNU-9556/ S Kim. [Holotype, in SNU].

Diagnosis. This species is superficially close to Agnoea josephinae (Toll, 1985) in having dark brown ground color of forewing, but it can be easily distinguished by the mixed with gray scales of ground color and two fuscous dots in the forewing and the dark brown basal part of the 3 rd segment of labial palpus. The male genitalia of the new species are similar to A. josephinae (Toll, 1985) and A. elsae (Svensson, 1982) in having rather a bell-like uncus and a tougue-shaped gnathos, but it can be differentiated from them by the sclerotized and a finger-shaped sacculus bearing a convex middle part.

Description. Adult ( Figs. 1 A–B). Head: Frons dark brown mixed with pale yellow; vertex dark brown. Scape of antenna pale yellowish brown entirely, shorter than diameter of eye; flagellum pale yellow and dark brown alternately. Labial palpus dark brown, except pale yellowish brown on ventral margin of 1 st and 2 nd segment and apical part of 3 rd segment; second segment longer than third segment. Thorax: Thorax and tegula grayish dark brown dorsally. Wing expanse 19.0 mm. Forewing ground color dark brown; two fuscous dots at 2/5 and 2/3 of forewing; fringes dark brown tinged with pale yellow near termen. Hindwing broad, ground color and fringes grayish dark brown, the latter tinged with pale yellow near termen.

Male genitalia ( Figs. 1 C–E). Uncus bell-like, wide at base, gradually narrowed to apex, slightly concave laterally. Gnathos tongue-shaped, half length of uncus. Valva symmetric, setose from 1/4 to apex, gradually concave on costal margin; sacculus sclerotized finger-shaped, extended to sup-apex of valva, slightly convex at 1/2 of sacculus, gradually narrowed beyond the half to sub-apex of valva. Vinculum extended with hairy caudal margin. Aedeagus with sharp apex, slightly bent at sub-apex, as long as tegumen.

Female unknown.

Distribution. Korea.

Etymology. The species name is derived from the Latin, digiti- (=finger) plus a Latin diminutive suffix – ella, referring to the finger-shaped sacculus of the male genitalia.
