Hylaeus (Hylaeus) moricei ( Friese, 1898)

Warncke (1972, 1986, 1992a) considered the name Hylaeus nigrifacies Bramson, 1879 to have priority over H. moricei and designated a neotype of H. nigrifacies to fix the nomenclature ( Warncke 1986). Although a lectotype is not currently designated, the name H. moricei has been used more frequently than H. nigrifacies in recent years. We here follow Warncke’s interpretation and consider H. moricei sensu auctorum as H. nigrifacies Bramson, 1879 . This species includes three subspecies that require further investigation: the nominate subspecies which is distributed from eastern Germany to Iran, H. n. moricei in Israel and Egypt, and H. n. rhenana ( Warncke, 1986) distributed from Spain to western Germany ( Warncke 1992a). According to Schmidt et al. (2015), European COI sequences are assigned to two significantly divergent BINs (Barcode Index Numbers). Whether these two BINs correspond to distinct subspecies remains to be investigated. We only retain Hylaeus nigrifacies in the present checklist, awaiting further revision.
