Comment on type specimens: In stating “Fand sich verschiedentlich in Sendungen des Hrn. Krebs aus dem Kaffernland”, Klug (1842: 327,328) implied that there were more than one specimen he examined and therefore all type material are considered syntypes (ICZN 1999: Article 73.2) and available for lectotype designation (ICZN 1999: Article 74.1). We have designated the lectotype and three paralectotypes from specimens from type material held in ZMB and MNHN.

Diagnosis: Erymanthus gemmatus can be confused with E. transversopustulatus n. sp. and E. testaceus. Erymanthus testaceus has white setae on gibbosities A, C and D. Erymanthus transversopustulatus n. sp. is 18– 20mm long and has black setae on gibbosity B and black legs with two light brown crossbands on each femur.
Length: (29 specimens measured) 8–13mm (average 9.72mm).
Head: Yellow to brown with a dark triangular spot, tapering posteriorly; frontal umbo light; with short light pilosity and with isolated long dark hairs; antennae distally darker.
Pronotum: Pronotal length to width ratio 1.03:1 to 1.21:1 (average 1.11:1); yellow to brown, with characteristic dark pattern (Fig. 39 F); broadest behind middle; gibbosities plane; with isolated punctation; with dorsally long dark, laterally white pilosity.
Scutellum: Black; vested with white setae.
Elytra: Elytral length to width ratio 1.69:1 to 2.02:1 (average 1.83:1); apical half of elytra conspicuously broader, yellow to brown, with variable dark markings; always with spots next to scutellum; punctation in the anterior half always lighter; first 3–4 rows of punctation slightly rasp-like; punctation coarse, almost circular and anteriorly in distinct rows, anteriorly interstices smaller than diameter of punctation; pilosity with long dark and short white hairs; gibbosities B and E yellow, the others brown; gibbosities A, C and E with dark and dense setal tuft, D sometimes with dark setae, B with white setal tuft.
Legs: Yellow, tibiae proximally darker, femora with dark pattern around the middle.
Lower surface: Dark brown, with white pilosity.
Male genitalia, pygidium, ventrite VI: Tegminal lobes one-tenth of tegmen length, tips of tegminal lobes pointed; tegminal struts broadened until two-thirds of whole length and then tapering concavely; phallic tip hooklike in lateral view; posterior side of pygidium angular; tips of ventrite VI blunt.
Distribution: Central African Republic, Uganda, Kenya, Tanzania, Malawi, Zimbabwe, South Africa.
Seasonal occurrence: Collected from June to February.
