Puplesis, genitalia slide nos AN416, AN417, AN418 ( ZIN); 4 ♂ (not type series), same locality as holotype, 13–21.viii.1986, R . Puplesis ( ZIN); 4 ♂ (not type series), same locality as holotype, 20.vii.–15.viii.1990, R . Puplesis ( ZIN); 2 ♂ (not type series), same locality as holotype, 30.vi.–19.vii.1991, R . Puplesis and A. Diškus ( ZIN) ; 5 ♂ (not type series), Turkmenistan, Kugitangtau , env. Svinsoviy (Svinsovyy) Rudnik, Sajat, 12–13.viii.1989, 29.viii.1990, R . Puplesis ( ZIN).

Diagnosis. This species belongs to the Ectoedemia angulifasciella species group. Externally, it can be confused with some other species possessing a large hair pencil of the hindwing, surrounded by ochre scales ( Fig. 80 ). Nevertheless, the combination of a large, brown tuft and long special piliform scales along the costal margin on the forewing underside ( Fig. 79 ) has some value in differentiation of E. tadshikiella .

In the male genitalia, the unique, apically rounded valva and short, rounded lobes of the vinculum ( Fig. 203 ) instantly distinguish E. tadshikiella from other species of the group.

Remarks. Forewing length 1.7 mm; wingspan 3.7 mm. Forewing underside with a large, dark brown tuft and long bristles along costal margin ( Fig. 79 ). Hindwing upper side with a large, ochre-brown hair pencil, surrounded by ochre androconial scales ( Fig. 80 ). For a full description see Puplesis 1994: 200, 201.

Bionomics. Host plant and leaf mine are unknown. Adults were collected from late June to August.

Distribution. Known from the Hissor Range, Tajikistan ( Fig. 1 : Hr), at altitude about 1200 m, and adjacent Kugitangtau Range (eastern Turkmenistan).

Remarks. We provide the first photographic documentation of the male genitalia of E. tadshikiella ( Figs 198– 205 ) and report on the type-series transfer: the holotype and six paratypes of E. tadshikiella , earlier deposited at LEU (=VPU) will be transferred to ZIN (see Material & Methods).
