Andrena (Micrandrena) nitidula Pérez, 1903 and Andrena (Micrandrena) distinguenda Schenck, 1871

Remarks. These two species have been deeply confused in the literature, predominantly deriving from the variable treatment of this complex by Warncke (discussed in Wood 2023a). In short, two species are present (but also see below for the presence of a third species A. puella that is restricted to Corsica and Sardinia), though there is currently no consensus between morphological and genetic concepts. For the purpose of this revision, both A. nitidula (Liguria only) and A. distinguenda (widespread) are considered present in Italy following the revision of Burger and Herrmann (2003). Andrena distinguenda was listed by Comba (2019) [species 62], but not A. nitidula .
