Ectoedemia species 219

(Figs 74–79)

Material examined. 13, RUSSIA (Far East), Primorskiy Kray, 20 km E Ussuriysk, Gornotayezhnoe, 24.vii. 1983, leg. R. Puplesis, gen. slide no. AG 219 (ZIN).

Diagnosis. This species belongs to the Ectoedemia subbimaculella group. The male is recognized by a combination of the grey-white fascia of forewing, a weakly developed brownish hair-pencil surrounded by a patch of whitish androconia, and features of the male genitalia (broad valva, weakly developed central element of gnathos, very short vinculum).

Male (Fig. 74). Forewing length 2.5 mm; wingspan 5.5 mm (n=1). Head: palpi brownish cream; frontal tuft orange; collar orange-cream, comprising piliform scales; scape orange-cream; antenna with 35–36 segments, slightly shorter than half forewing length; flagellum pale brown on upper side, cream to pale brown on underside. Thorax: dorsum and tegulae pale brown. Forewing pale grey-brown, speckled with dark grey-brown and fuscous scales, with oblique grey-white median fascia; cilia pale brown; underside uniformly pale brown to dark brown (depending on angle of view). Hindwing pale grey-brown on upper side and underside; hair-pencil very weakly developed, comprises a few pale grey-brown to dark brown setae, surrounded by a patch of white or grey-white androconia; cilia pale grey-brown. Legs pale brown, glossy. Abdomen: male genitalia (Figs 75–79) with capsule considerably longer (256 mm) than wide (194 mm). Ventral plate of vinculum very short, lateral lobes absent (Figs 76, 77). Pseuduncus triangular (Fig. 77). Gnathos with long narrow lateral arms and weakly developed central element (no caudal process) (Figs. 76, 77). Valva (Fig. 75) 199 mm long, broadened medially, with strongly slerotized basal margin and short apical process; transtilla with long slender transverse bar and short slender sublateral processes. Aedeagus (Figs 78, 79) about 263 mm long (possibly partially everted in figs 78, 79) and relatively slender (66–77 mm); vesica thickened laterally and with with numerous minute cornuti (Fig. 79).

Female. Unknown.

Bionomics. Host-plant unknown; possibly a leaf-miner on Quercus . Adults fly in July (attracted to light).

Distribution. It occurs in dense, mostly deciduous forests of Primorskiy Kray (Fig. 2).

Remarks. This new species left unnamed because of the poor quality of the material.
