Changes in subgeneric classification 5

A recent study (Haider et al., 2013) on the phylogeny and floral hosts of Osmia bees of the subgenera Monosmia, Osmia and Orientosmia revealed paraphyly of the largest subgenus Osmia. Given this paraphyly in conjunction with the pronounced morphological resemblance among the species of all three subgenera, the authors propose to to merge Monosmia (1 species), Osmia (25 species) and Orientosmia (3 species) into one single large subgenus Osmia.
