Morphological diagnosis

Osmia (Hemiosmia)   species are nonmetallic, robust and medium-sized bees (8–12 mm) with punctiform parapsidal lines, a largely polished basal area of the propodeum and tergal hair bands, which—depending on the species—are distinctly or sparsely developed, foxy red or whitish and continuous or interrupted. Diagnostic character of the females is a large median tooth on the lower inner margin of the mandible in combination with a strongly carinate trochanter of the fore leg. The metasomal scopa is either foxy red, yellowish-red or whitish. Unifying characters of the males are two lateral teeth and one or two median teeth at the apical margin of tergum 6 rendering tergum 6 three- or four-toothed ( Fig. 5–7 View FIGURES 1–7 ), and a rather small tergum 7, which is hidden under tergum 6. As in most males of Osmia   , sternum 2 is more or less enlarged, sternum 3 is medially both emarginate and fringed and sternum 6 lacks membraneous basal flaps. The male of Osmia spinicoxa   spec. nov. differs from the males of the other O. ( Hemiosmia   ) species in that tergum 6 lacks median teeth ( Fig. 13 View FIGURES 8–13 ).
