Andrena (Graecandrena) graecella Warncke, 1965

Remarks. Listed by Comba (2019) [species 79] citing Warncke (1967). However, this is because Warncke’s cre- ation of the name A. graecella was based on the female material of A. strymonia Pittioni, 1950 . Andrena strymonia was described with a male holotype, and the male is conspecific with A. (Aciandrena) aciculata Morawitz, 1886 . Warncke (1965) recognised that the female belonged to a different species, and described it as A. graecella . He then used this name to apply to a species found in southern and south-eastern Europe. He then realised ( Warncke 1973) that Pittioni’s material was actually distinct from the widespread southern species, and so he described this latter species as A. (Graecandrena) hyemala Warncke, 1973 . Therefore, references by Warncke to A. graecella published between 1965 and 1973 actually refer to A. hyemala , which is the species present in Italy, and which is additionally listed by Comba (2019) as species 80.
