Nomina dubia

Brood cells of Hoplitis (Alcidamea) mitis (Nylander, 1852) under a removed stone (left) and female of the same species collecting pollen on Campanula, the species’ exclusive pollen source (right); the brood cells consist of leaf fragments imbricately glued together, forming a cone-like structure.

Holotype severly damaged (only head, thorax, fore and middle leg remaining), rendering assignment to species impossible; the linear parapsidal lines indicate that the species belongs to Hoplitis rather than to Osmia (Melanosmia) as assumed by Ungricht et al. (2008) (A. Müller, unpublished).
