Andrena ( Plastandrena) oligotricha Mavromoustakis, 1952

Andrena oligotricha was considered to be a valid species by Varnava et al. (2020). However, we consider it a synonym of Andrena bimaculata ( Kirby, 1802) ( Figs 3E, F ) based on genetic data ( Wood 2023b), the lack of morphological differentiation from A. bimaculata , particularly in the genital capsule, the presence of this red colour form in Turkey and the Levant, and we thus return to the hypothesis proposed by Gusenleitner & Schwarz (2002).

FIGURE 3. A. Andrena fulica Warncke, 1974 male, habitus in lateral view. The taxonomic review of Wood et al. (2020b) shows that the taxon Andrena astrella Warncke, 1975 is a junior synonym of this species. B. A. fulica male, frontal view of the head. C. Andrena assimilis Radoszkowski, 1876 female, habitus in lateral view. The taxonomic review of Wood & Monfared (2022) shows that the taxon Andrena gallica Schmiedeknecht, 1883 is a junior synonym of this species. D. A. assimilis female, frontal view of the head. E. Andrena bimaculata (Kirby, 1802) female, habitus in lateral view. Unpublished data from T.J. Wood agrees with the baseline of Gusenleitner & Schwarz (2002) and indicates that the taxon Andrena oligotricha Mavromoustakis, 1952 is a junior synonym of this species. F. A. bimaculata female, frontal view of the head. Pictures by Paolo Rosa.
