D i s t r i b u t i o n: Europe, including European part of Russia (NIKITSKIY et al. 1996: 36; DEDYUKHIN et al. 2005: 300; SEMENOV 2009: 48), Turkey, East Siberia.

B i o n o m i c s: The specimens from the Chita area have been collected from Pleurotus pulmonarius (FR.) QUÉL.

C o m m e n t: WÜSTHOFF (1937: 143) described from Siberia a new subspecies G. joyi asiatica, which differs from the nominal taxon by lighter coloration, coarser and more distinct punctation of the elytra and a more slender аedeagus. We did not examine the holotype of G. joyi asiatica, however we studied additional material from Europe and the European part of Russia, which are in all characters similar to the Siberian specimens and no significant differences in the shape of the aedeagus or elytral sculpture were detected. Concequently, the following new synonymy is established: Gyrophaena joyi WENDELER 1924 = G. joyi asiatica WÜSTHOFF 1937 , syn. nov. Aedeagus as in Fig. 4 . It is here reported from Irkutsk and Chita areas for the first time.
