( Figs 1–5 , 22, 23, 26 , 28–30 ) Type material. Holotype : ♂, Far East RUSSIA , Primorskiy Kray, 20 km E Ussuriysk, Gornotayezhnoe, Biological Station, 5.viii.2011 , leg. A. Rocienė, genitalia slide no. AG428 ( ZIN ). Diagnosis. This species belongs to the Ectoedemia suberis group and to most closely resembles the other recently described East Asiatic species, E. ortiva Rocienė & Stonis. Both species ( E. ortiva and E. paraortiva sp. nov. ) differ from other Ectodemia by the broad phallus with numerous spine-like cornuti. The new species ( E. paraortiva sp. nov. ) differs from E. ortiva by the absence of a fascia on the forewing ( Fig. 22 ) (in E. ortiva the fascia is well developed, see Fig. 24 ), also by the more grey hindwing with a long, weakly visible hair-pencil, which is not surrounded by a yellowish cream patch of androconia ( Fig. 23 ) (in E. ortiva this patch is very characteristic, see Fig. 25 ) (also see Remarks). Male ( Figs 22, 23 ). Forewing length about 2.0 mm; wingspan about 4.4 mm. Head: palpi grey-cream; frontal tuft pale orange; collar whitish, comprising loose lamellar scales; scape cream; antenna with 30 segments, almost half as long as forewing; flagellum grey on upper side and underside. Thorax: dorsum and tegulae concolorous with base of forewing. Forewing grey-brown, apically more coarsely speckled with darker scales; fascia absent; cilia pale grey-brown; underside of forewing uniformly dark grey-brown. Hindwing ( Fig. 23 ) brownish grey or dark grey on upper side and underside; hair-pencil slender and long (longer than half of hindwing), but not prominent (hardly visible), grey-cream (but not surrounded by a patch of cream androconia as in E. ortiva , Fig. 25 ); costal margin remains brownish grey; cilia pale grey to grey. Legs brown-cream, shaded dark brown on upper side. Male genitalia ( Figs 26 , 28–30 ). Capsule longer ( 270 mm ) than wide ( 180 mm ). Vinculum very broad ( 180 mm ), with two very short but very broad lateral lobes ( Figs 26 , 28 ). Pseuduncus triangular ( Fig. 28 ), damaged in genitalia slide no. AG428 ( Fig. 26 ). Gnathos with long lateral arms and slender caudal process ( Fig. 28 ). Valva ( Fig. 29 ) 170 mm long, curved inwardly, gradually narrowed towards apex, with pointed apical process; transtilla with slender and long sublateral processes ( Figs 26 , 28 ). Phallus ( Fig. 30 ) broad ( 100 mm ), 220 mm long, with two apical carinae; vesica with numerous spine-like or similar cornuti of different sizes ( Fig. 30 ). Although the phallus of E. paraortiva sp. nov. tends to be slightly smaller than that of E. ortiva , the new species is not distinguishable on basis of the phallus (see comparison of E. ortiva and E. paraortiva sp. nov. in Figs 30, 31 ); Female. Unknown. Bionomics. Host-plant unknown; possibly a leaf-miner on Quercus (as the other species of the Ectoedemia suberis group). The only known specimen was collected in early August (attracted to light). Distribution . The type locality is in dense, deciduous mostly broad-leaf forests of Primorskiy Kray ( Figs 1–5 ). Etymology. This species is named after Ectoedemia ortiva Rocienė & Stonis , a closely similar (and presumably closely related) species recently described from the same locality in Primorskiy Kray as the new species (see Rocienė & Stonis 2013). Remarks. We suppose that E. ortiva and E. paraortiva sp. nov. are probably two sympatric species.
