Araeopteron patella sp. n.

( Figs. 12 , 22, 27 )

Material examined. Holotype: female, RUSSIA, Primorye terr., Krounovka, 30 km W Ussuriisk, 30.viii– 3.ix. 1998 (V. Kononenko), genit. prep. 5863 M. Fibiger. Coll. M. Fibiger (to be deposited in ZMUC). Paratype: SOUTH KOREA, 1 female, Mt. Cheonggyae, GG, 12.VII. 1976 (K.T. Park), genit. prep. 5121 NIAST. Coll. NIAST.

Diagnosis. A. patella is distinguishable from the other East Asiatic Araeopteron species by the less oblique, less narrow forewing; the shape of the antrum; and the shape and armature of the broad, plate-like signum in the female genitalia.

Description. Adult ( Fig. 12 ). Wingspan 10 mm. Antennae without lamellae, with scales. Labial palps strongly upturned, 3rd segment 2.0 times as long as 2nd. Head small, eyes large. Head, patagia and thorax light grey scaled. Terminal margin of forewing much less oblique than in other East Asiatic Araeopteron species. Ground colour of forewing and hindwing dark grey, forewing with light grey bands on both sides of antemedial line and apical half of postmedial area; hindwing almost unicolorous dark grey; both wings with discal spots. All crosslines indistinct, blackish, not oblique, terminal line on hindwing well marked, black; terminal line on both wings prominently indicated by black interveinal spots. Underside unicolorous grey, without pattern. Colour of abdomen basally and apically grey, medially dark grey. Female genitalia ( Figs. 22, 27 ). Antrum shaped as parallelogram, laterally with long extensions directed posteriorly; ductus bursae short and narrow, membranous; posterior part of corpus bursae cylindrical, coiled, anterior part ovoid, with broader then high plate-shaped signum; apical spines small, subapical spines longer, along crest, both groups of spines directed anteriorly.

Distribution. Russian Far East, southern Primorye terr. (Fig. 39) and South Korea.

Etymology. The name refers to the large plate-shaped signum with spines directed anteriorly.
