Diagnosis: Erymanthus transversopustulatus n. sp. can be mainly confused with E. belzebuth . In Erymanthus transversopustulatus n. sp. The gibbosities are really transverse and have a tuft of black setae, the lower surface is black, in E. belzebuth the metathorax is yellow to brown. In Erymanthus transversopustulatus n. sp. The hind tibiae are curved and black, in E. belzebuth the hind tibiae are almost straight and brown. The antennae in E. belzebuth are brown and bordered black, in E. transversopustulatus n. sp. The antennomeres are black from A6/A7 onwards.

Length: (3 specimens measured) 18–20mm (average 19mm).

Head: Light brown with characteristic black maculation, antennomeres from A6/A7 onwards totally black; frontal umbo with large rounded grooves; with dense fine punctation concentrated between the eyes; with flavous pilosity concentrated between the eyes.

Pronotum: Pronotal length to width ratio 0.96:1 to 0.98:1 (average 0.97:1); light brown with black maculation ( Fig. 41 C); gibbosities elevated, posterior gibbosities evenly conical, pronotal groove inconspicuous; with dense fine punctation; with quite dense flavous and black pilosity.

Scutellum: Black; vested with flavous setae.

Elytra: Elytral length to width ratio 1.96:1 to 2.04:1 (average 2.00:1); light brown with black maculation; punctation large, circular, not conspicuously rasp-like, width of interstices variable, irregularly distributed; with short, black pilosity; gibbosities oblong-ovate, all gibbosities with tuft of black setae.

Legs: Black, femora with two light brown bands, procoxa light brown; hind tibiae curved.

Lower surface: Black, except prothorax; light spots laterally on each abdominal segment; with dense flavous and flavotestaceous pilosity.

Male genitalia, pygidium, ventrite VI: Not available, all specimens are females. Distribution: Kenya.

Seasonal occurrence: Collected from December to January.
