Key to the species of the genus Anaxius (males only).
1. Intercoxal process of prosternum strongly depressed in apical part (lateral view). Elytron with setation composed of short, yellowish bristles and elongate black stiff setae ( Fig. 1C, F View FIGURE 1 ). Protarsus slightly dilated ( Fig. 1F View FIGURE 1 ). Metafemora with small denticles ( Fig. 2D View FIGURE 2 )............................................................................................ 2
-. Intercoxal process of prosternum straight or slightly depressed in apical part (lateral view). Elytron bare or with inconspicuous bristles ( Fig. 1A, B, D–G View FIGURE 1 ). Protarsus distinctly dilated (at least basal tarsomere) ( Fig. 1A View FIGURE 1 ). Metafemora not covered with small denticles............................................................................................. 3 bristles in apical part ( Fig. 1B View FIGURE 1 ). Inner side of mesofemora with preapical denticle ( Fig. 1F View FIGURE 1 ).................... prozeskyi -. Mesotibia evenly curved ( Fig. 1C View FIGURE 1 ). Underside of profemora not covered with bristles. Inner side of mesofemora without preapical denticle ( Fig. 1C View FIGURE 1 ).................................................................... limpopoensis
3. Elytron covered with small, shiny, tubercles ( Fig. 1A View FIGURE 1 , 2E View FIGURE 2 ). Only basal tarsomere of protarsus widened, remaining tarsomeres extremely narrow ( Fig. 1A View FIGURE 1 ). Mesotarsus with apical tarsomere widened ( Fig. 2F View FIGURE 2 ). Mesotiba flattened laterally ( Fig. 2F View FIGURE 2 )............................................................................................... bloubergensis
-. Elytron covered with punctures. Basal tarsomere of protarsi widened, with subsequent tarsomeres slightly narrower ( Fig. 1E View FIGURE 1 ). Mesotarsus with relatively narrow first tarsomere. Mesotibia not flattened laterally.................................. 4
4. Protibia with deep median cavity ( Fig. 2G View FIGURE 2 ). Metatibia bent inwards ( Fig. 1D, E View FIGURE 1 ).................................... 5
-. Protibia without or with shallow median cavity. Metatibia not bent inwards........................................ 6
5. Meso- and metafemora simple. Metatibia bent more medially ( Fig. 1D View FIGURE 1 ).................................. meletsensis
-. Mesofemora with preapical denticle ( Fig. 1E View FIGURE 1 ). Metafemora with fringe of bristles on underside. Metatibia bent more basally ( Fig. 1E View FIGURE 1 )....................................................................................... obesus
6. Body size = 6.5–7.0. Mesofemora with preapical denticle ( Fig. 1B View FIGURE 1 ). Aedeagal tegmen narrowed periapically ( Fig. 3B View FIGURE 3 )................................................................................................. campbellae
-. Body size ca. 4.5. Mesofemora simple. Aedeagal tegmen evenly narrowed towards apex ( Fig. 3E View FIGURE 3 ).......... pseudoloensus
