Diagnosis. This species belongs to the Ectoedemia angulifasciella species group. Externally, the combination of a brown to grey cream hair pencil surrounded by brown or ochre-brown (occasionally brown and white cream together) androconial scales of the upper side of the male hindwing ( Figs 70–72 View FIGURES 65–72 ) and a tuft of transverse bristles on the underside of male forewing ( Figs 67–69 View FIGURES 65–72 ) distinguishes E. spinosella from the most representatives of the group, except for E. tadshikiella ; however, the latter has different male genitalia.

In the male genitalia, the combination of a very wide pseuduncus ( Figs 174, 175 View FIGURES 174–178 , 179, 180 View FIGURES 179–184 ), small caudal pro-cess of the gnathos ( Figs 176 View FIGURES 174–178 , 181, 182 View FIGURES 179–184 ), and pointed apical process of the valva ( Figs 174 View FIGURES 174–178 , 182 View FIGURES 179–184 ) distinguishes E. spinosella from other species of the group.

Remarks. Forewing length 1.5–2.3 mm; wingspan 3.2–5.0 mm. Forewing underside with a brown ( Fig. 67 View FIGURES 65–72 ) to brownish cream ( Fig. 68 View FIGURES 65–72 ) tuft of long bristles scales; occasionally the tuft can appear only as a few bristles (probably undeveloped or rubbed) ( Fig. 69 View FIGURES 65–72 ). Hindwing upper side with a brown, pale grey-brown ( Figs 70, 71 View FIGURES 65–72 ) or brownish cream ( Fig. 72 View FIGURES 65–72 ) hair pencil, surrounded by brown ( Fig. 70 View FIGURES 65–72 ) or ochre-brown ( Figs 71, 72 View FIGURES 65–72 ) androconial scales. In the type series of the former E. albiformae , some males with white cream androconia, some with brown, and some with both (mostly white and a few brown). For a full description see Nieukerken 1986 or Johansson et al. 1990; for a description of the former E. albiformae (now synonymized with E. spinosella ), see Puplesis & Diškus 2003; for a description of the former E. petrosa (synonymized with E. spinosella ), see Puplesis 1994: 199, 200.

Bionomics. Host plants are Prunus spp., Rosaceae . The leaf mine was described and illustrated by Johansson et al. 1990: 317, 318 (fig. 753). In Asia (the western Kopet Dag Range), larvae mine in May–early July; in Europe, from late June to October ( Johansson 1990). In Asia (the western Kopet Dag Range), adults were collected in May–June; in Europe, adults fly in June–July ( Johansson 1990).

Distribution. Known from Europe (except the northern regions) and the mountain ranges of Central Asia, where it seems to be abundant ( Puplesis & Diškus 2003): the western Kopet Dag Range, Turkmenistan, at elevation of about 800 m ( Fig. 1 View FIGURES 1–6 : Ko) and Hissor Range, Tajikistan ( Fig. 1 View FIGURES 1–6 : Hr) (new distribution).

Remarks. We provide the first photographic documentation of the type-series specimens of S. albiformae Puplesis & Diškus (synonymized with S. spinosella ) and E. petrosa Puplesis (now synonymized with E. spinosella ), and report on new distribution of E. spinosella in Tajikistan. The holotypes and paratypes of E. albiformae and E. petrosa , earlier deposited at LEU (=VPU) will be transferred to ZIN (see Material & Methods).
