description: Erymanthus vesuvioides Thomson, 1856
(Figs 37–38, 41 E)
Thomson 1856: 114, t5 f8; Murray 1867: 319; Schenkling 1903: t5 f9; Schenkling 1906: 282.
Specimens examined: Lectotype (designated here): Gd. Bassam, Type J. Thom., Vesuvioides Thoms. R. Z. 56.114.5.3., Ex Musaeo James Thomson, Muséum Paris 1952, Coll. R. Oberthúr, (MNHN).
Comment on the type specimens: As Thomson (1856: 114, 115) does not mention number of specimens, it cannot be assumed that E. vesuvioides is based on a single specimen. The specimen from Grand Bassam is therefore considered a syntype (ICZN 1999: Article 73.2) and available for Lectotype designation (ICZN 1999: Article 74.1).

Diagnosis: Erymanthus vesuvioides can be confused with E. melanurus. Erymanthus melanurus is 9–12mm long and has light brown femora. Erymanthus vesuvioides is clearly recognizable by its black metafemora and the total length of 12–20mm.
Length: (31 specimens measured) 12–20mm (average 15.77mm).
Head: Light brown, on disc darker; frontal umbo with two rounded grooves; with flavous anteriorly directed pilosity; antennae brown.
Pronotum: Pronotal length to width ratio 1.06:1 to 1.18:1 (average 1.11:1); light brown, posteriorly darker; pronotal groove dark and quite deep; gibbosities inconspicuous; with dense fine punctation; with relatively dense anterior directed flavous pilosity.
Scutellum: Black; vested with white setae.
Elytra: Elytral length to width ratio 1.82:1 to 2.18:1 (average 1.98:1); anterior half light brown, posteriorly dark brown to black; conspicuously dilated apically; punctation basally circular, apically elongate-ovate, first 2–4 rows slightly rasp-like, width of interstices variable, irregularly distributed; anteriorly with isolated black and flavous pilosity, posteriorly partly with dense white and flavous pilosity; gibbosities A, B, C and D with dense white setal tuft, E with black setae.
Legs: Pro- and middle legs light brown with dark marking dorsally on the femora, hind legs dark brown to black.
Lower surface: Dark brown to black with indication of light spots lateral of each abdominal segment; with white pilosity.
Male genitalia, pygidium, ventrite VI: Tips of tegminal lobes blunt, tegminal lobes one-fifth length of tegmen; tegminal struts broadened until one-fourth length and tapering lanceolate until tip; phallic tip clavate; posterior side of pygidium angular and very slightly pointed; processes of ventrite VI pointed.
Distribution: Guinea, Sierra Leone, Ivory Coast, Cameroon, Central African Republic, Equatorial Guinea, Gabon.
Seasonal occurrence: Collected from November to August.
