– Pronotal sculpture consisting of fine polygonal cells with large central grains; subparallel species (Figs 3,5,15).......... 3

3 - Smaller species, distal antennomeres of male (4–10) much wider than long; vertex as wide as width of eye; pronotal sculpture homogeneous, lateroposterior depressions missing ( Fig. 3 ); aedeagus ( Fig. 20 ) short, almost spindle-shaped, weakly sclerotised; 4.8 mm; Zimbabwe......................................................

4– Blue species, elytra twice as long as wide; sculpture of pronotal disc consisting of fine, transverse, polygonal cells without central grains ( Fig. 8 ); anal ventrite of male widely truncate to shallowly emarginate; male metatibiae with sharp inner serrations ( Fig. 24 ); aedeagus ( Fig. 17 ) widely spindle-shaped, flattened; 7.5–8.6 mm; DRC.............. A. (H.) caerulea sp. nov.

– Dark bronze or red-bronze species, elytra 1.7–1.9 times as long as wide; sculpture of pronotal disc consisting of fine, simple punctures; anal ventrite of male narrowly rounded; male metatibiae with very fine, inner serrations; aedeagus narrower.... 5

5– Pronotum 1.6–1.7 times as wide as long; elytra uneven, 1.7–1.8 times as long as wide; male metatibiae with rather sharp, inner serrations ( Fig. 25 ); parameres with large, sharp, dorsolateral projection at posterior third ( Fig. 18 ); 6.3–9.3 mm; CAR, DRC, Kenya, Malawi, Mozambique, RSA, Rwanda, Tanzania, Uganda, Zambia, Zimbabwe.......... A. (H.) dispar Kerremans

– Pronotum 1.8–1.9 times as wide as long; elytra only very weakly uneven, 1.8–1.9 times as long as wide; male metatibiae without or with very fine, inner serrations ( Fig. 23 ) or with small group of fine teeth at anterior part of inner emargination ( Fig. 23 ); parameres without sharp, projection at posterior third or only with small, hardly visible, obtuse projection.............. 6

6 – Male metatibiae wider, flattened, without distinct, inner serrations ( Fig. 27 ); frons flat to weakly depressed; frontal pubescence denser and longer on postclypeal part of frons; aedeagus – ( Fig. 21 ); 5.7–7.8 mm; Benin, Burkina Faso, Cameroun, Ivory Coast, Senegal, Sierra Leone, Togo......................................................
