The predominantly Holarctic bee genus Osmia Panzer is species-rich and
behaviourally diverse. A robust phylogeny of this genus is important for
understanding the evolution of the immense variety of morphological and
behavioural traits exhibited by this group. We infer a phylogeny of Osmia
using DNA sequence data obtained from three nuclear genes (elongation
factor 1-α, LW-rhodopsin and CAD) and the mitochondrial gene COI. Our
taxon sampling places special attention on North American members of the
subgenus Melanosmia Schmiedeknecht; we discuss the novel placement of a
number of species traditionally assigned to O. (Melanosmia) and examine
the relative support for alternative classifications of this species-rich
subgenus. We use this new phylogeny to guide a reassessment of
morphological and behavioural characters within Osmia. Our results provide
support for the recognition of Osmia (Hapsidosmia), subgen.n., a monotypic
subgenus containing Osmia iridis Cockerell & Titus. We synonymize
Osmia (Mystacosmia) Snelling under O. (Melanosmia), syn.n. We synonymize
Osmia (Acanthosmioides) Ashmead under O. (Melanosmia), syn.n., propose
‘odontogaster species group’ as a replacement for the subgeneric name
Acanthosmioides, and refine the morphological characters that serve to
diagnose the species group. We additionally propose ‘nigrifrons species
group’ for a clade within O. (Melanosmia) containing most species formerly
placed in Osmia (Centrosmia) Robertson. We demonstrate more cohesive
patterns of nest substrate use in the nigrifrons and odontogaster species
groups than was previously believed to occur, reconsider character
polarity of aspects of the female mandible, and show that a large number
of morphological characters have evolved convergently within the genus. In
order to facilitate discussion of relevant taxa, we propose the following
15 new synonymies: O. bakeri Sandhouse under O. melanopleura Cockerell; O.
crenulaticornis Michener under O. pinorum Cockerell; O. claremontensis
Michener under O. sedula Sandhouse; O. cockerelli Sandhouse under O.
dakotensis Michener; O. francisconis White under O. enixa Sandhouse; O.
hurdi White under O. austromaritima Michener; O. sladeni Sandhouse under
O. nifoata Cockerell; O. titusi Cockerell under O. phenax Cockerell; O.
subtrevoris Cockerell, O. physariae Cockerell, and O. erecta Michener
under O. giliarum Cockerell; and O. universitatis Cockerell, O. integrella
Cockerell, O. amala Cockerell, and O. metitia Cockerell under O.
nigrifrons Cresson, syn.n. We remove O. wyomingensis Michener from
synonymy with O. nifoata Cockerell, stat.n., and O. pinorum Cockerell from
synonymy with O. physariae Cockerell, stat.n.
