D i s t r i b u t i o n: Central Europe and European part of Russia, East Siberia.

B i o n o m i c s: This species has been collected from Inocybe sp.

C o m m e n t: Aedeagus as in Fig.10 . This species is characterized by the variably shaped apical margin of tergite VIII: some specimens from the same fungus (in our material) may have one small bump between two long lateral teeth ( Fig. 12 ), while others have two small bumps ( Fig. 11 ). This variability was previously reported by LIKOVSKY (1964) and LOHSE (1974). This species is here reported from Siberia for the first time.
