71. Boletina dubia (Meigen, 1804)

Material.

5♂♂, A-1; 3♂♂, A-3. Total: 8♂♂.

Distribution in Georgia.

Adjara.

General distribution.

Europe.

Remarks.

The Georgian specimens have the ventral lobe of the gonostylus with a blunt small spine apically that is absent in studied specimens from Estonia and Sweden as well as in published figures (e.g. Landrock 1927, Hutson et al. 1980, Zaitzev 1994). Otherwise, the male terminalia including aedeagal complex do not have any substantial differences. Therefore, the Georgian material is considered to be conspecific pending further, more thorough study including that based on DNA sequencing.
