Acylophorus orientalis 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 2011). 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 larger, pronotum 1.8x or less wider than head ( Figs. 1–8 in Lott 2010); head strongly and abruptly depressed at base underneath ( Fig. 29 in Lott 2 010); pubescence behind eyes denser and more extensive; genae not expanded forward in front of eyes. No or only narrow pigmented area beyond antennal insertion. Meso- and metatarsi with four first segments with short terminal setae, last segment with long empodial setae.

The group contains 9 species from continental sub-Saharan Africa and two following species from Madagascar.
