E. M. Laasonen & L. Laasonen 1994: Endothenia oblongana and E. marginana (Lepidoptera, Tortricidae) in Finland, With Description of a New Subspecies. - Entomologica Fennica 5: 189-196.
The Finnish Endothenia sp. called E. gentianaeana (Hübner) for more than a hundred years is shown to be E. oblongana (Haworth), a species occurring also in the other Nordic countries. To our knowledge, E. marginana (Haworth) has a discontinuous distribution in Finland, Sweden, and East Karelia. On the basis of the distribution and differences in appearance a new subspecies Endothenia marginana tarandina ssp. n. is described, with data on its biology.
