Osmia lamina is a species of Hoplitis (Anthocopa)

Osmia lamina Pérez, 1896 is, based on the original description, a Hoplitis species of the subgenus Anthocopa rather than of Alcidamea. The description of the female of H. maghrebensis by Zanden (1992) refers to the female of Hoplitis lamina (see post “New synonymies 5”).
