Diagnosis: Erymanthus revoili can be confused with E. ater , E. horridus and E. pustulosus . Erymanthus ater is recognizable by the long antennomeres 9–11. Erymanthus horridus has gibbosities with testaceous setal tuft. Erymanthus pustulosus has black setal tuft on gibbosity D. Erymanthus revoili is recognizable by the conical pronotal gibbosities, conspicuous rasp-like punctation and characteristic tegminal struts.

Length: (19 specimen measured) 12–16mm (average 13.32mm).

Head: Black, sometimes lighter; antennomeres 1–8 brown to dark brown, antennomeres 9–11 black; frons with flattened gibbosity; with anteriorly directed pilosity.

Pronotum: Pronotal length to width ratio 0.96:1 to 1.06:1 (average 1.00:1); light brown to yellow, with characteristic black markings ( Fig. 40 E); dorsal gibbosities conspicuously conical; with isolated brown pilosity.

Scutellum: Black, vested with white setae.

Elytra: Elytral length to width ratio 2.14:1 to 2.50:1 (average 2.33:1); dark brown with diaphanous crossbands; strongly dilated apically; with conspicuously rasp-like punctation in basal half, at basal margin with a prominent cone, punctation circular, interstices very variable, punctation irregularly distributed; with isolated dark pilosity; gibbosities A, B, C and E with black setal tuft, D with white setae.

Legs: Dark brown, femora distally lighter; tibiae partly with long setae.

Lower surface: Dark brown with fine punctation; with short white pilosity.

Male genitalia, pygidium, ventrite VI: Tips of tegminal lobes blunt, tegminal lobes one-fifth length of tegmen; tegminal struts broadened after one-seventh of length and tapering after four-sevenths, last one-seventh of struts narrow with dichotomous tip; phallic tip hook-like; posterior side of pygidium rounded; processes of ventrite VI rather pointed.

Distribution: Kenya, Tanzania, DR Congo, Zambia, Zimbabwe, Mozambique, South Africa.

Seasonal occurrence: Collected from October to February.
