83CCB15DC1CA525AABC657414DD37FBC.taxon	diagnosis	Diagnosis. This species can be easily distinguished from other Digitivalva species by its bright orange colour with silvery-white stripes on the forewing. The male genitalia are similar to those of D. arnicella (Heyden, 1863) by sharing the absence of a horizontal split in the costal arm of the valva and developed sacculus, and the broad vinculum-saccus combination. Male genitalia of this species can easily be distinguished from those of other Digitivalva species by possessing a single vertical split on each costal arm of the valva and a C-shaped valva (sacculus broad, extraordinary in D. arnicella). The female genitalia are similar to those of D. arnicella in the absence of a signum; however, this species can be distinguished by the ovally rounded ostium bursae (triangular in D. arnicella).	en	Zhang, Xinyu, Yagi, Sadahisa, Hirowatari, Toshiya (2024): A remarkable new species of the genus Digitivalva Gaedike, 1970 (Lepidoptera, Glyphipterigidae, Acrolepiinae) from Japan.

Fringe dark brown, white in the middle of outer margin. Hindwing ground colour khaki grey to brownish grey with one stout frenulum in male; posterior smoothly rounded; greyish-white scales present between the costal margin and median cell.

CuA 1 and CuA 2 from lower angle of discal cell separated, rather close at the base; CuP present, reaching posterior margin. 1 A + 2 A running to 2 / 3 of posterior margin. Hindwing: Sc + R 1 connected with costal margin at basal 4 / 5. Rs running to near apex; M 1 and M 2 stalked. M 3 and CuA 1 stalked; CuA 2 from lower angle of discal cell; CuP reaching posterior margin. 1 A + 2 A running to 1 / 3 of posterior margin; 3 A present. Abdomen dark yellowish-grey. Female (Figs 1 B, 2 B). Wingspan: 8.0 – 12.0 mm in paratypes (n = 32). Forewing length: 3.5 – 6.0 mm in paratypes (n = 32). No sexual dimorphism exists. Female sometimes darker in colour than males. Hindwing with two slender frenular bristles. Male genitalia (Fig. 3 A – D). Tuba analis wide, triangular, membranous, curved downward in lateral view. Anellus well sclerotised. Valva symmetric, well sclerotised; sacculus produced; costal arm developed with vertical single split at apex, forming the whole valva into C-shaped; long stiff setae covering both sacculus and costal arm at apex. Vinculum strongly sclerotised, round V-shaped; saccus weakly submembranous, not obvious. Phallus curved ventrally in lateral view, and broad anteriorly; bulbus ejaculatorius relatively oval-shaped. Female genitalia (Fig. 4 A, B). Papilla analis nearly triangular, clothed with both short- and medium-stiff hairs, and submembranous. Intersegmental membrane between seventh and eighth sterna has a symmetric, strongly sclerotized triangular sterigma. Ostium bursae ovally rounded. Ductus bursae rather long, moderately membranous; corpus bursae attached to the end of ductus bursae membranous, oval, without signum. Ductus seminalis attached to posterior portion of corpus bursae near the end of ductus bursae, long, broaded at attaching point to corpus bursae, membranous. Pupae (Figs 5 A – C, 7 E – G). Length 6.5 – 7.5 mm; width approximately 1.5 mm (n = 11, including exuviae). General colouration of pupal exuviae yellowish-brown. Body nearly cylindrical, fusiform, surface rough. Vertex bearing a small subtriangular process, forming a distinct cocoon cutter at the centre. Labrum short, round, triangular. Antennae and forewing extend to posterior margin of A 4 (fourth abdominal segment). Galea reaching posterior margin of A 3. Prothoracic, mesothoracic, and metathoracic legs extended to the middle of A 3, middle of A 4, and anterior margin of A 5, respectively. Prothorax with one pair of projections at anterolateral corners of tergum. Spiracles conical, strongly elevated; each pair varies in length from A 2 to A 7; spiracles not visible on A 1 and partially closed on A 8. Two pairs of short setae symmetrically present on anterior 1 / 3 of mesothoracic tergum; a pair of short setae symmetrically present on anterior 1 / 3 of metathoracic tergum.
