Key to Megachile species of Montana: female specimens (i.e., 10 flagellomeres, 6 tergites)
1 Metasomal sternites with white apical setal bands between scopal setae ( Fig. 6A View FIGURE 6 ); T2 with lateral, ovate fovea........... 2
- Metasomal sternites without white apical setal bands between scopal setae; T2 without lateral, ovate fovea.............. 3
2 S5 scopal setae all black; clypeal margin with small median tubercle ( Fig. 6D View FIGURE 6 ); T3 with lateral, ovate fovea................................................................................. Megachile (Eutricharaea) apicalis Spinola View in CoL
- S5 scopal setae white, sometimes apical half with black setae; clypeal margin without median tubercle, essentially straight; T3 without lateral, ovate fovea........................................ Megachile (Eutricharaea) rotundata (Fabricius) View in CoL
[Note: Megachile (Eutricharaea) pusilla Pérez also keys out at 2’. This species has not been recorded from Montana but is an introduced species that could potentially occur in the state. Megachile pusilla has black setae laterally on T5–6 at most, while M. rotundata has black setae laterally on T2–6.]
3 Metasoma rounded in dorsal view, T2–3 widest, then narrowing from T4–6 ( Fig. 6B View FIGURE 6 )............................... 4
- Metasoma subparallel in dorsal view, T2–4 subequal in width ( Fig. 6C View FIGURE 6 )......................................... 32
4 Tergites without white apical setal bands; T1–2 covered in pale yellow to white pubescence contrasting entirely dark pubescence on T3–5............................................................................................. 5
- Most tergites with white apical setal bands; T1–2 sometimes with pale pubescence, but T3–5 without entirely black pubescence.......................................................................................... 7
5 S2–6 scopal setae orange; T6 usually with pale appressed setae............. Megachile (Xanthosarus) melanophaea Smith View in CoL
