Diagnosis: Erymanthus maculaticeps can be confused with E. belzebuth , E. semirufus , E. variolatus and E. flavonotatus . Erymanthus semirufus , E. flavonotatus and E. variolatus have at least two flavotestaceous abdominal segments. Erymanthus belzebuth and E. variolatus have dark markings basally and just before the middle of femora. Erymanthus maculaticeps is clearly recognizable by its dark abdomen and the basally darker femora.

Length: (7 specimens measured) 11–14mm (average 12.43mm).

Head: Light brown, posteriorly darker; frontal umbo with two grooves; with anteriorly directed flavous pilosity; antennomeres from A3 onwards black.

Pronotum: Pronotal length to width ratio 1.07:1 to 1.15:1 (average 1.12:1); with dense fine punctation; light brown; gibbosities and pronotal groove inconspicuous; with isolated flavous pilosity.

Scutellum: Black; vested with white setae.

Elytra: Elytral length to width ratio 2.05:1 to 2.24:1 (average 2.19:1); elytra lighter brown than head and pronotum, one black spot on each side in basal half; punctation circular to slightly elongate-ovate, first 2–4 rows slightly rasp-like, basally distinct rows visible, interstices half to same width as diameter of punctation; with isolated flavous and black pilosity; gibbosities A, B, C and D with white setal tuft, E with dense fine punctation.

Legs: Light brown, tibiae darker; indication of a dark spot on pro- and mesofemora, mesofemora basally darker, its metafemora dark from base towards middle; coxae except for procoxae (with light spot) dark.

Lower surface: Dark brown to black, each abdominal segment with a pale spot laterally; meso- and metathorax black, with dense white pilosity.

Male genitalia, pygidium, ventrite VI: Tips of tegminal lobes pointed, tegminal lobes one-eighth length of tegmen; tegminal struts narrow, broadened until three-sevenths length and tapering lanceolate until tip; phallic tip clavate; posterior side of pygidium rounded; processes of ventrite VI neither pointed nor blunt.

Distribution: Guinea, Ivory Coast.

Seasonal occurrence: Collected from September to March.
