Andrena (Ulandrena) concinna Smith, 1853

WARNCKE (1966; 1973).

NOTE. There is a lack of clarity surrounding A. concinna sensu stricto because of the taxonomic concepts used by Warncke. He treated the many species allied around A. concinna as subspecies because of the difficulty in separating the females, for example describing A. concinna resoluta from North Macedonia and Bulgaria but then listing it simply under A. concinna in the faunal summary ( WARNCKE, 1973). As true A. concinna was described from Albania ( GUSENLEITNER & SCHWARZ, 2002) it is possible that it is present in Bulgaria. However, this must be demonstrated with male material as confident determination can only be made from inspection of the genital capsule.
