Remarks

The taxonomic history of the two names A. assimilis and A. gallica is long and confused (SchmidEgger & Scheuchl 1997; Gusenleitner & Schwarz 2002), in part due to the unclear location of the type material of A. gallica , which was recently rediscovered ( Le Divelec 2021). The putative criteria used to separate material was in the colour of the wing venation and the degree of infuscation of the wing itself ( Osytshnjuk et al. 2008; Motyka et al. 2016). However, this character is highly variable. Examination of the type of A. assimilis in Berlin shows that, though the wings are somewhat infuscate, the veins are not entirely dark, with intermixed dark and light veins, particularly the basal vein ( Fig. 137 View Figs 133–138 ). In contrast, the type of A. gallica (and more broadly all examined specimens from southern France) has hyaline wings with almost uniformly golden veins (see illustrations in Le Divelec 2021).

Problems with the proposed two-species classification can most easily be seen in Iberia. In the Pyrenees, the light form is present (e.g., A. gallica iberica , Fig. 140 View Figs 139–144. 139–140 ), extending across the northern parts of Spain ( Fig. 145 View Figs 145–148 ) and down the Atlantic coast as far as the Algarve in southern Portugal. However, in central and southern Spain forms with dark infuscate wings can be found that show both light and dark veins in the same wing (Madrid, Fig. 146 View Figs 145–148 ). In the Sierra Nevada (Granada, at 2100 m a.s.l., Fig. 147 View Figs 145–148 ) and the Sistema Central (Ávila, 1300 m a.s.l., Fig. 148 View Figs 145–148 ) forms with extremely dark wings and wing venation can also be found. This increased melanism is even more apparent in Morocco, where populations in the Atlas Mountains ( A. assimilis barnei ) are entirely dark, including all of their body hair.

Warncke treated A. gallica as a subspecies of A. assimilis , and in his distribution map ( Gusenleitner & Schwarz 2002) he presented a clean picture of three separated populations: A. assimilis s. str. in the southern Balkans, Turkey, and the Caucasus; A. assimilis gallica in continental Europe and Russia; and A. assimilis barnei in Morocco. However, Warncke was inconsistent with his determination of material from this group, as specimens listed here from Azerbaijan, Iran, Kazakhstan, Kyrgyzstan, and Serbia with golden wing venation were determined as A. assimilis s. str. He also determined specimens from Spain as both assimilis s. str. and assimilis gallica , contradicting the clean picture presented in his distribution map. Likewise, Osytshnjuk et al. (2008) argue that both A. assimilis and A. gallica are present from Eastern Europe eastwards, Western and Central Europe containing only A. gallica . The situation is reminiscent of the taxonomic confusion present in Bombus (Thoracobombus) concerning B. laesus Morawitz, 1875 and B. mocsaryi Kriechbaumer, 1877 , which vary in hair colour and are present in sympatry across much of Eastern Europe. Though varying in their hair colour, these taxa were recently found to belong to the same broad taxon ( Brasero et al. 2021).

Due to this extensive variation within A. assimilis , including in the type specimen itself, which does not unambiguously show uniformly dark wing venation, A. gallica is synonymised under A. assimilis . This includes the subspecies described by Bischoff (1922, Figs 139–144 View Figs 139–144. 139–140 ), which were previously synonymised under A. assimilis gallica by Warncke (1967) but were listed under A. gallica by Gusenleitner & Schwarz (2002).

Distribution

Andrena assimilis is distributed across the West and Central Palearctic, from Morocco (absent from the rest of North Africa and the Levant) across continental Europe to Turkey, northern Iran *, Russia (European part to Eastern Siberia), and Central Asia ( Gusenleitner & Schwarz 2002; Proshchalykin et al. 2017a). It is unclear why Warncke did not include the Soika and Mavromoustakis record from northern Iran in his distribution maps for this species, since he clearly examined and determined it.
