Ectoedemia insignata Puplesis, 1988: 281–282 .

Ectoedemia insignata Puplesis, in Puplesis 1994: 201 , figs 649–651.

Material examined. 6 ♂, 3 ♀ (holotype and paratypes): Tajikistan, 30 km N Dushanbe, Varzob Canyon , Kondara, elevation ca. 1200 m, 27.vi–21.viii.1986, R . Puplesis, genitalia slide nos AD574 (holotype), AN 419♂, AN 420♂, AN421#, AN422#, AN423# ( ZIN, also see Remarks ) . 3 ♂, 1♀: Tajikistan, same locality, 13.vi–19.vii.1991, R . Puplesis and A. Diškus, genitalia slide nos AN 464♂, AN 467♂ ( ZIN) .

Diagnosis. This species belongs to the Ectoedemia angulifasciella species group. Externally, E. insignata differs from species of the group in the white tegula and white basal spot of the forewing ( Figs 58–60 ). The combination of brown hair pencil surrounded by ochre androconial scales of upper side of male hindwing ( Figs 63, 64 ) and presence of few transverse bristles on the underside of male forewing ( Figs 61, 62 ) also distinguishes E. insignata from other representatives of the group.

In the male genitalia, the combination of wide, plate-like caudal process of gnathos ( Figs 159 , 168 ), presence of large apical spines of phallus ( Fig. 170 ), and absence of lateral lobes of the vinculum ( Figs 161, 162 , 172 ) distin-guishes E. insignata from other species of the E. angulifasciella group.

Remarks. Forewing length 2.2–2.5 mm; wingspan 4.6–5.3 mm (n = 6). For a description see Puplesis 1994: 201.

Bionomics. Host plant is unknown. Adults fly in June–August, and October. Otherwise, biology is unknown.

Distribution. Known from a single locality in Hissor Range, Tajikistan (Varzob Canyon: Kondara) at elevation of about 1200 m ( Fig. 1 : Hr).

Remarks. We provide the first photographic documentation of the male genitalia ( Figs 159–173 ). The holotype and eight paratypes, earlier deposited at LEU (=VPU) will be transferred to ZIN (see Material & Methods).
