Hylaeus (Prosopis) praenotatus F̂rster, 1871

This species was reinstated as a European species by Ortiz-Sánchez et al. (2002). The main diagnostic trait that they mention is the red colour of the first tergum (e.g. Ortiz-Sánchez et al. 2003). The type of H. praenotatus is a black specimen of H. gibbus Saunders, 1850 ( Le Divelec 2022). The records of H. praenotatus sensu Ortiz-Sánchez et al. (2003) might refer to any of three European species of the gibbus species-group that can exhibit black to reddish gaster: H. gibbus , H. incongruus F̂rster, 1871 and H. purpurissatus (Vachal, 1895) . We do not include H. praenotatus in the present checklist. Barcoded specimens of this taxon reported from Portugal by Baldock et al. (2018) genetically match H. incongruus (T.J. Wood, unpublished data).
