Erymanthus vesuvioides Thomson, 1856
( Figs 37–38 View FIGURE 37 View FIGURE 38 , 41 View FIGURE 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.
