Striae of elytra indistinctly punctate .Hind metatarsi somewhat longer than upper thorn and as long as next three joints together. 7-8 mm Group 31: Aphodiellus 68 (67) Pronotum and elytra always distinctly punctate. 69 (70) Hind metatarsi shorter than upper thorn of hind tibiae. Apical thorn of anterior tibiae in males opposite to middle outer tooth: species of Group 18: Cinacanthus, with a weak basal border on pronotum. 70 (69) Hind metatarsi always longer than upper thorn of hind tibiae. 71 (72) Elytra strongly reticulated, mostly also punctated, almost dull, black, rarely reddish brown. Clypeus emarginate, both sides rounded or denticulated. Genae mostly produced, front at most with a weak tubercle. Hind metatarsi as long as upper thorn. 4-7 mm Group 32: Amidorus 72 (71) Elytra shiny, at most finely reticulate and punctate. 73 (76) Upper surface unicoloured yellowish red or brown, at most disc of pronotum and of elytra darker. 74 (75) Front without tubercles, suture distinct. Clypeus emarginate, genae either produced or not. Hind angles of pronotum mostly obtuse, rarely lightly truncated or weakly emarginate. Scutellum narrow. 2-5.5 mm Group 33: Koshantschikovius 75 (74) Front with three small tubercles (both lateral elevations sometimes weak or absent). Clypeus either shallowly emarginate or not, genae distinctly produced. Hind angles of pronotum obtuse. 6-7 mm Group 34: Pseudacrossus 76 (73) Upper surface black, elytra often yellow with various dark pattern, or black with yellow spots . 77 (78) Elytra black with or without bright spots on shoulders and on apex. Clypeus emarginate, genae produced beyond eyes. Frontal suture very fine or absent. 2-4.5 mm Group 35: Orodalus 78 (77) Elytra yellowish with various dark pattern. 79 (80) Elytra with black suture and mostly with a triangular scutellar spot. Clypeus deeply emarginate, both sides of emargination lobed and distinctly upturned. Genae not or weakly produced. Frontal suture very fine, without tubercles. Scutellum narrow. 2-5 mm Group 36: Mesontoplatys 80 (79) Elytra with a nebulous spot on disc, sides and apical part more bright. Clypeus weakly or not emarginate, both sides rounded, genae small, not or scarcely produced beyond eyes. Frontal suture very fine or absent, only in A. hepaticus Roth with a tubercle. Scutellum triangular. 2.5-5.5 mm Group 37: Nobius Group 1: Pleuraphodius 1 (10) Disc of pronotum not or scarcely with sparser and finer punctures than sides (cf. also A. levis Schmidt, No. 29). 2 (3) Very small species. Reddish yellow, shiny, elytra shortly setose. Genae not produced beyond eyes, clypeus weakly emarginate. Hind metatarsi longer than upper thorn of hind tibiae and somewhat shorter than next three joints together. 2.5 mm. - Botswana (pusio Kolbe, 1908) 3 (2) Bigger species, 3-4.5 mm long. Elytra bald. 4 (7) The broad primary intervals obtusely carinated, the secondary ones linear. 5 (6) Punctation of head fine, very dense, most distances between punctures smaller than diametei\ of punctures. Brown. Clypeus broad, broadly emarginate. Basis of pronotum with short bristles. Hind metatarsi much longer than upper thorn and almost as long as next three joints together. 3-3.5 mm. - RSA (Natal) mutilus Schmidt, 1911 6 (5) Punctation of head distinctly stronger, most distances between punctures as broad or broader than diameter of punctures. Reddish brown, elytra more yellow. Apex of clypeus narrower, emargination less broad. Basis of pronotum without bristles. Hind legs about as in preceding species. 3-3.2 mm. - RSA (Transvaal), Zimbabwe-Rhodesia stehliki Endrődi, 1977 7 (4) Primary Intervals only convex. 3 (9) Clypeus weakly emarginate, genae distinctly produced beyond eyes.
