Stigmella dorsiguttella (Johansson, 1971)

Diagnosis. Males of S. dorsiguttella are usually immediately recognized by the combination of a pale head and the very conspicuous yellow to orange scaling of hindwing. In some specimens this scaling may, however, be more brownish (perhaps as a result of ageing), then it more closely resembles S. eberhardi, which has still darker brown bronze scales on hindwing. On the underside of the forewing dorsiguttella has a distinct patch of androconials reaching about 2/3, whereas eberhardi has a uniform cover of dark brown scales. The forewing of dorsiguttella usually has a pale stripe along dorsum (hence its name). Males of S. zangherii could be confused because of similar, but usually paler androconials, but the head in zangherii is usually black. Females resemble most other pale-headed species, but dorsiguttella is the only one with a pale dorsum.
Male genitalia very similar to those of S. trojana and bicuspidata, short valval process and wide aedeagus characteristic. Female genitalia characterised by the almost globular bursa with longer spines mostly at one side, and a group distally in ductus; ductus spermathecae with about 5 convolutions.
