Andrena (Micrandrena) simontornyella adianta Warncke, 1974

Andrena simontornyella adianta Warncke 1974:12, 38 (Holotype examined)

Diagnosis. This subspecies is very similar to the nominate subspecies. It is recognized by a convex clypeus that is not flattened in the center of the lower half, with fine and weak folds. The clypeus has a microsculpture in the apical region that is coarser than in A. simontornyella simontornyella . The process of labrum is more or less triangular, and the basal area of propodeum has fine ornamentation on the central and back regions. The propodeal triangle is defined, and the metasomal marginal zones are more marked than in the nominate subspecies. The male has not yet been described.

Comment. The male of A. simontornyella adianta is unknown, so a greater effort must be made for its capture. Both subspecies are rare in the Iberian Peninsula, which is reflected in the small number of specimens found for this work.
