A. salifi group ( Lott 2010)

Diagnosis. Disc of pronotum glabrous except for a pair of setae; pubescence on head restricted to small area behind eyes; apex of styles at tip of abdomen covered by bristles and more or less invisible ( Fig. 30 in Lott 2010). Pronotum shining, either without microsculpture or, much more rarely, with scattered and sparse micro-punctures. Only last segment of maxillary palpi pubescent, penultimate segment glabrous ( Figs. 51–69 in Lott 2010); two pairs of interocular setae present on head. Head smaller, pronotum 1.9x or more wider than head ( Figs. 18–20 in Lott 2010); ventral depression at base of head shallow (Fig. 108 in Lott 2010); pubescence behind eyes sparser and less extensive; genae expanded forward in front of eyes. No pigmented area beyond antennal insertion. Metatarsi with four first segments with long terminal setae, last segment with short empodial setae ( Figs. 87, 88 ).

The group contains 4 species from sub-Saharan continental Africa, four following species from Madagascar and one species from Mauritius (Mascarene Islands).
