– Vein 2rm absent (Fig. 1e) ................................................................................................................. 2

2. Scutellum completely smooth, scutellar foveae weakly impressed and not sharply delineated (Fig. 2a–b) .............................................................. A. insularis Mata-Casanova & Pujade-Villar sp. nov.

– Scutellum from strongly alutaceous to strongly areolate, scutellar foveae may be basally defined or not, but always clearly distinguishable from the rest of the scutellar surface (Figs 2e–f, 3b–d,f) ..... .......................................................................................................................................................... 3

3. Notauli complete (Fig. 2e–g) ........................................................................................................... 4

– Notauli incomplete, effaced in anterior mesoscutum. (Fig. 3b–d,f) ................................................ 7

4. Notauli with clearly defined horizontal carinae (Fig. 2e–f); pronotum carinate across its surface (Fig. 2c) ............................................................................................................................................ 5

– Notauli lacking horizontal carinae; if present, then very weak (Fig. 2g); pronotum smooth to coarse, at most with few ventral carinae (Fig. 2d) ....................................................................................... 6

5. Region between notauli region strongly carinate, scutellum areolate (Fig. 2e) ................................. .................................................................................................................... A. kozlovi Kovalev, 1974

– Region between notauli smooth and shiny; central scutellum smooth, only margins are areolate (Fig. 2f) .......................................................................................... A. romseyensis Fergusson, 1975

6. Mesopleuron with some antero-basal carinae which can be anteroposteriorly extended but never covering most of mesopleural surface (Fig. 2d) ................................... A. nitidulus (Dalman, 1823)

– Mesopleuron with densely wrinkled in anterior to central parts (Fig. 3a) .... A. ustulatus Belizin, 1973

7. Scutellar foveae not defined posteriorly, interfoveal line incomplete (Fig. 3b) ................................. ................................................................................................................ A. longicellus Belizin, 1951

– Scutellar foveae defined posteriorly by a carina, which can be more or less apparent, but always distinguishable; interfoveal line complete (Fig. 3c–f) ..................................................................... 8

8. Scutellum alutaceous; short, blunt projection present posteriorly (Fig. 3c) ....................................... ........................................................................................................... A. flavidicornis (Kieffer, 1911)

9. Notauli excavated, extending over 1/3 of mesoscutal total length, almost reaching the pronotum in some individuals (Fig. 3d); parascutal sulcus shallowly excavated but always present (Fig. 3e) ...... ............................................................................................................ A. atricornis Fergusson, 1985

– Notauli superficial, extending less than 1/3 of mesoscutal total length (Fig. 3f); parascutal sulcus absent (Fig. 3g) ........................................................................................... A. paucus Belizin, 1961
