Key to Males

1. Proboscis at repose surpassing posterior coxa. Clypeus strongly protuberant, clypeocular distance 0.72–0.96 times MOD. Hypostomal carina with strong, anterior spiniform projection ( Fig. 12C View FIGURE 12 )................................. A. halictoides

- Proboscis at repose barely surpassing anterior coxa. Clypeus less protuberant, clypeocular distance 0.3 times MOD or less. Hypostomal carina anteriorly at most with rounded elevation ( Fig. 12D View FIGURE 12 )......................................... 2

2. First and second segments of labial palpus with modified, hooked setae.......................................... 3

- First and second segments of labial palpus with simple setae, not hooked. …...................................... 6

3. Scape without yellow mark ( Fig. 3A View FIGURE 3 ). Ventral part of mesopleuron without projection in front of mid coxa. Posterior basitarsus with rounded apex ( Fig. 10A View FIGURE 10 ). Posterior tibia with under surface nearly glabrous and ventral inner margin with tubercule continued apically by carina up to tibial spur. T 3– T 5 with brownish hairs on discs and distinct white to yellowish apical bands ( Fig. 2A View FIGURE 2 )..................................................................................... A. bonariensis

- Scape with yellow mark ( Fig. 3C View FIGURE 3 ). Ventral part of mesopleuron with projection in front of mid coxa. Posterior basitarsus with pointed apex ( Fig. 3B–D View FIGURE 3 ). Posterior tibia with under surface densely pilose and ventral inner margin without tubercule nor carina, or with carina medially, not reaching to tibial spur. Discs of T 2– T 5 and apical bands with yellow-golden hairs ( Fig. 2C–D View FIGURE 2 )............................................................................................. 4

4. Posterior basitarsus with inner curved tooth between basal third and middle of basitarsus ( Fig. 10D View FIGURE 10 )..... A. mesopotamica

- Posterior basitarsus without inner tooth ( Figs. 10C View FIGURE 10 , 5A View FIGURE 5 )...................................................... 5

5. S6 strongly emarginate ( Fig. 4A View FIGURE 4 ). Under surface of basitarsus clothed with hairs to apex. Femur dark, with light brown dorsolateral mark ( Fig. 2C View FIGURE 2 )....................................................................... A. holmbergi

- S6 weakly emarginate ( Fig. 5B View FIGURE 5 ). Under surface of basitarsus clothed with hairs on basal half; apical half bare. Femur light brown without evident light mark................................................................ A. ursinus

6. Posterior basitarsus with basal inner tooth ( Fig. 11A–B View FIGURE 11 ). S6 with emarginate apex. Smaller species, length of forewing 4.0–6.0 mm ................................................................................................ 7

- Posterior basitarsus with basal inner rounded projection followed by median tooth ( Fig. 11C–D View FIGURE 11 ). S6 with truncate apex. Larger species, length of forewing 6.1–7.6 mm ................................................................... 8

7. Scape and pedicel black ( Fig. 8B View FIGURE 8 ). Pronotal lobe black. Femora and tibiae black to dark brown ( Fig. 7B View FIGURE 7 ).... A. nigricornis

- Scape and pedicel orange to light brown ( Fig. 8A View FIGURE 8 ). Pronotal lobe orange to light brown. Femora and tibiae orange to light brownish ( Fig. 7A View FIGURE 7 )......................................................................... A. apiformis

8. Scape and pedicel orange ( Fig. 8C View FIGURE 8 ). Forewing with dark spot apical to marginal cell, remainder of wing margin lighter (as in Fig. 6C View FIGURE 6 ). Posterior basitarsus with rounded apex ( Fig. 11C View FIGURE 11 )........................................... A. romeroi

- Scape and pedicel black ( Fig. 8D View FIGURE 8 ). Forewing with entire apical margin darkened (as in Fig. 6D View FIGURE 6 ). Posterior basitarsus with pointed apex ( Fig. 11D View FIGURE 11 )....................................................................... A. saltensis
