Remarks

Material from southwestern Spain closely resembles Moroccan specimens, but are generally less hirsute, particularly in the single male Spanish specimen, although this may be simply due to the condition of the individual specimen ( Figs 101–108 ). Structurally, there are no clear differences, and so they are considered to be conspecific. The pronouncedly Atlantic distribution of Morocco and southwestern Iberia is not unprecedented in bees, as the extremely rare Lasioglossum musculoides Ebmer, 1974 has a global distribution of the Souss Valley in southwestern Morocco and southwestern Portugal ( Pauly 2015). Coastal areas of Huelva and Sevilla continue to produce records of range-restricted species thought to be endemic elsewhere, such as Flavipanurgus fuzetus Patiny, 1999 which was discovered there in 2018 ( Cross & Wood 2018).

Pollen loads taken from three specimens at a single Moroccan locality contained pure Reseda - type ( Resedaceae Martinov ) pollen ( Table 2 ), so the floral observation data from Spain is consistent with this picture. Comparisons with other species are complicated because the former subgenus Poliandrena Warncke, 1968 in which it was placed ( Warncke 1974) has been found to be strongly polyphyletic, and Poliandrena in a strict sense is now a synonym of the subgenus Ulandrena Warncke, 1968 ( Pisanty et al. 2021). Excluding A. polita Smith, 1847 (now subgenus Ulandrena ) and A. florea Fabricius, 1793 (the placement of this species necessitates the erection of a new subgenus) which clearly belong elsewhere ( Pisanty et al. 2021), other members of the old concept of Poliandrena that can be found in Spain for which pollen data are available are predominantly associated with Reseda L., with the exception of A. farinosa Pérez, 1895 which is likely a specialist of Fabaceae ( Table 2 ). These taxa fall into at least two clades ( Pisanty et al. 2021), and so work is needed to establish their true subgeneric affinities in addition to their dietary choices.

Distribution

Previously thought to be endemic to Morocco, now also including Spain ( Warncke 1974; Lhomme et al. 2020).
