Andrena ( Chlorandrena ) taraxaci Giraud, 1861 Literature records Popov (1967) ; Osytshnjuk et al. (2005) . Reason for exclusion The species concept of A. taraxaci has changed enormously, with many distinct taxa now being recognised after the broad concept adopted by Warncke (see Schwenninger 2015 ). As a result, it is unclear as to whether older publications apply a broad or narrow species concept, and so A. taraxaci s. str. is excluded from the Iranian fauna until specimens can conclusively demonstrate its presence (see comments under A. astica and A. orientana ).
