Aedeagus (fig. 2, 6). Spermatheca (fig. 3, 1). D i s t r i b u t i o n. Europe, Siberia (Schülke & Smetana, 2015). Comments. The original description of G. pseudonana is based on an unspecified number of syntypes collected collected “sie wurde bei Rundhang in Målselv in Nord-Norwegen am 18. Juni 1937 an kleinen Scheibenpilzen zwischen Salix-Sträuchern am Ufer des Flusses in Gesellschaft zahlreicher nana gefunden. Einige weitere Stücke wurden in Anspülicht bei Rundhang und bei Moen in Målselv gefunden. Sie liegt ferner von Sel in Gudbrandsdal vor, wo ich ein ♀ am 6. Juni 1929 fand.,wie auch von Sorum in Vågå wo Munster ein Ơ im Juli 1932 erbeutet hat” collected by Merkmalen (Strand, 1939). A male syntype found in the collection of NHMO is designated as lectotype is done for the better fixation of the identity of the name Gyrophaena pseudonana A. Strand, 1939.
