Diagnosis. A. nebulosa is distinguished from other East Asiatic Araeopteron species by the pale grey ground colour of wings, with well marked dark pattern and a prominent black discal spot. The male genitalia differ by having a relatively long, subapically bent uncus and presence of three small pointed, triangular ampullae; vesica with long, broad sclerotised patch of small, narrow spines. The female differs by having a broad shuttlecock-shaped signum with moderately long spines.

Description. Adult ( Figs. 5, 6 View FIGURES 1 – 12 ). Wingspan 11–13 mm. Antennae of both sexes without lamellae, with scales. Labial palps strongly upturned, 3rd segment 2.5 times as long as 2nd. Head small, eyes large. Head, patagia, thorax, and ground colour of forewing and hindwing grey, suffused with black-grey patches; hindwing with prominent black medial line; both wings with prominent discal spot. All crosslines present, often indistinct or interrupted; terminal line prominently indicated by black interveinal spots. Underside unicolorous grey, with pattern. Colour of abdomen basally and apically grey, medially dark grey. Male genitalia ( Fig. 15 View FIGURES 13 – 19 ). Uncus relatively long, subapically bend; membranous part of valva widest 2/3 from base, there smoothly angeled; sacculus regularly tapered, widest and rounded apically, there ventrally curved; clasper fused to sacculus, with three very small pointed, triangilar ampullae. Aedeagus medium long and narrow; vesica with long, broad sclerotised patch, comprising very many small, narrow spines. Female genitalia ( Figs. 23, 28 View FIGURES 20 – 29 ). Antrum vertically narrow, somewhat trapezoid, but with large lateral, posterior extensions; ductus bursae relatively short and narrow, membranous; posterior part of corpus bursae cylindric, anterior part ovoid, with broad shuttlecock-shaped signum, which has broad convexity with long spines in opposite direction.

Distribution (Fig. 36). Russia, southern Primorye terr., South Korea, China (Prov. Henan), Japan (Hokkaido, Honshu, Shikoku, Kyushu). This species is reported for China for the first time.

Araeopteron kurokoi Inoue, 1958 View in CoL , Tinea View in CoL , 4: 230, (not illustrated). TL: Japan, Fukuoka Pref., Mt. Hikosan [BMNH, London].

Inoue, 1965: 83, Pl. 15, figs 5A, 5B (imago), text fig. 6 (male genitalia); Sugi, 1982, I: 806, II: 381, pl. 196, fig. 70 (imago); Poole, 1989: 115.

Diagnosis. This species differs from other Araeopteron species in continental Asia by its prominent wing pattern, especially the presence of a large discal spot on the forewing. In the male genitalia the valve is broad, with the sacculus ending in an abruptly enlarged, comma-like process.

Distribution. Japan: Honshu, Shikoku, Kyushu. The species is not found in the continental Far East, but is listed here because of its occurrence in Japan, and possibly in South Korea.
