Andrena (Avandrena) heterodoxa Pérez, 1903 and Andrena (Avandrena) siciliana Warncke, 1980

Remarks. Both of these species were described from single specimens collected from Sicily ( Pérez 1903; Warncke 1980). Warncke (1967) misinterpreted A. heterodoxa as a synonym of A. (Euandrena) bicolor Fabricius, 1775 because he was never able to inspect the type, but Wood (2023c) located this material and confirmed the conspecificity of A. siciliana and A. heterodoxa . Pérez’s specimen is undated, and Warncke’s specimen was collected in 1858, and so it is possible that A. heterodoxa has not been recorded for over 150 years. It is suspected to be narrowly oligolectic on Erodium ( Geraniaceae ) based on the pollen preferences of closely related species ( Wood 2023a), so target searches should be made on this genus.
