Andrena (Micrandrena) Ashmead 1899

Abstract

SubgenusMicrandrenaAshmead, 1899 Genetics. Before discussing the genetics, it is necessary to highlight two taxonomic actions. The first is that Andrena corpana Warncke, 1965 (described from Larisa in Greece) is currently treated as a junior synonym of Andrena simontornyella Noskiewicz, 1939 (Gusenleitner and Schwarz 2002: 701). The second is that Pisanty et al. (2025) synonymised Andrena dargia Warncke, 1965 (described from Delphi in Greece) with Andrena minutula (Kirby, 1802); barcodes of “ Andrena dargia ” from the Peloponnese are presented here; these were also used in the analysis of Pisanty et al. (2025; Fig. 31). New barcodes of eastern Micrandrena are presented here, and the presence of Andrena oedicnema Warncke, 1975 in Greece is here discussed. There was some complexity seen with Andrena rugulosa Stöckhert, 1935 and Andrena illyrica Warncke, 1975, with A. illyrica intermixed between sequences of A. rugulosa. The rugulosa - group of species is taxonomically challenging with cryptic and only recently described Levantine species of high mountains (Pisanty et al. 2025), and the topology of this group is unstable; detailed analysis with additional samples is needed for clarity, and no action is taken here. Morphologically, the two taxa are separable, as indicated in the identification key.
