CharactersMegachile inexspectataMegachile leachella albipilaMegachile argentataVestitureVestiture of dorsal side of scutumEntirely consisting of white hairs; short scale hairs present over entire disc of scutum (Fig. 28)As in M. inexspectatascutum covered with intermixed light and dark hairs; short scale-like hairs mosty present anteriorly and posteriorly, less abundant on central parts of disc of scutumLateral hairs on tergaDark, erect hairs restricted to lateral parts of T6, sometimes T5 (Fig. 25)As in M. inexspectata (Fig. 34)Dark, erect hairs present laterally on T3-T6 (Fig. 15)Light hairs on disc of T6Sometimes forming one large spot of hairs (Fig. 25)Mostly forming two separated spots of hairsalways forming two well-separated spots of hairs (Fig. 15)SculpturePunctation of vertexDense, punctures small (diameter on average 40 μm) (Fig. 27)As in M. inexspectata, puncture diameters 35-40 μm, punctation slightly less dense, often with shagreened interspaces (Fig. 41)Punctures larger (on average 50 μm), punctation less dense, interspaces up to one puncture diameter, surface of interspaces smooth (Figs 1, 20)Punctation of disc of T4Dense, interspaces mostly smaller than one puncture diameter (Fig. 26)Mostly sparse, interspaces mostly larger than one puncture diameter (Fig. 34)Dense, interspaces smaller than one puncture diameter (Fig. 19)
