Ectoedemia rosae, a new species with disjunct distribution in the French Alps and Norway (Lepidoptera: Nepticulidae)

Abstract

The new species Ectoedemia rosae is described from France (Hautes Alpes) near Briancon, where adults were reared from leafmines on Rosa tomentosa and from adults collected in Norway, Vang, by sweeping bushes of Rosa majalis. The species belongs to the Ectoedemia angulifasciella group, and is closely related to E. hexapetalae (Szőcs, 1957) and the montane Rosa feeders E. rosiphila Puplesis, 1992 from Kazakhstan and E. marmaropa (Braun, 1925) from the USA (Utah). The latter is recorded new for California and Canada: Alberta and British Columbia. The large distances between the two localities of E. rosae are likely to represent a disjunct distribution rather than sampling errors and are discussed with respect to the resemblance in habitat type.
