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

摘要

A new species, Dictyna palmgreni >sp. 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 palmgreni >sp. n., Dictyna schmidti and Dictyna major Menge, 1869 are illustrated. The distribution of Dictyna palmgreni >sp. n. andDictyna schmidti is clarified. An unknown sac-like structure of the spermathecae of Dictyninae is briefly discussed.
