On a new Dictyna species (Araneae, Dictynidae) from the northern Palaearctic confused with the East Siberian D. schmidti Kulczyński, 1926

A new species, Dictyna palmgrenisp. n., is described from Finland and Russia on the basis of both sexes. Most of the earlier records of Dictyna schmidti Kulczyński, 1926 from the northern Palaearctic refer to this new species. Dictyna shilenkovi Danilov, 2000, syn. n. from Cisbaikalia is synonymised with Dictyna schmidti. The general appearances and copulatory organs of Dictyna palmgrenisp. n., Dictyna schmidti and Dictyna major Menge, 1869 are illustrated. The distribution of Dictyna palmgrenisp. n. andDictyna schmidti is clarified. An unknown sac-like structure of the spermathecae of Dictyninae is briefly discussed.
