Andrena (incertae sedis) urdula Warncke, 1965

Andrena urdula is challenging to morphologically characterise, and phylogenetic analysis suggests that it is best placed as incertae sedis for now (T.J. Wood, G. Pisanty, S. Bossert, unpublished data); it can be associated with the undescribed relata -group (see Wood 2023c).
