Genus: Osmia Panzer, 1806
Subgenus: Nasutosmia Griswold and Michener, 1998
Common name: none
Osmia (Nasutosmia) are slender bees that range in body length from 5–6 mm (Michener 2007). They have pale pubescence that sometimes forms narrow apical hair bands on the terga (Michener 2007). Osmia (Nasutosmia) was previously a subgenus of Hoplitis. In 2008, O. (Nasutosmia) was transferred from the genus Hoplitis to Osmia based on phylogenetic findings (Praz et al. 2008)
(modified from Michener 2007)
Osmia (Nasutosmia) may be confused with species within the subgenus Hoplitis (Alcidamea) due to similar small, slender body shapes, and the smooth, flat T1 with a longitudinal median groove (Michener 2007). Osmia (Nasutosmia) can be differentiated by the lack of a median pit on the male’s T7 and the female having a four-toothed mandible, which is three-toothed in H. (Alcidamea) (Michener 2007).
Osmia (Nasutosmia) are most likely specialists on Fabaceae (Müller 2018b).
Nesting behavior is unknown.
Osmia (Nasutosmia) contains two described species, O. corniculata and O. nasuta, and one undescribed species (Müller 2018b).
There are no known invasives.
Osmia (Nasutosmia) can be found in northern Africa, France, and Spain (Michener 2007).
