Congo , Kuilu, Mocquerys, Holotype , 1892, Ex Musaeo, W. Rothschild, 1899, Museum Paris 195-, Coll. R. Oberthúr (MNHN). Comment on the type specimen: The single specimen mentioned by Kuwert (1893: 479) from Kuilu, Congo from the Tring museum (now in MNHN), can be considered the holotype , fixed my monotypy (ICZN 1999: Article 73.1.2).

Diagnosis: Erymanthus melanurus can be confused with E. vesuvioides . Erymanthus vesuvioides is 12–20mm long and its metafemora are black. Erymanthus melanurus is 9–12mm long and can be recognized by its light brown femora. Length: ( 8 specimens measured) 9–12mm (average 10.5mm ). Head: Light brown; frontal umbo with two rounded grooves; with dark pilosity posteriorly, anteriorly with white pilosity; antennae yellow. Pronotum: Pronotal length to width ratio 1.11:1 to 1.12:1 (average 1.12:1); light brown; pronotal groove sometimes darker; gibbosities inconspicuous. Scutellum: Black; vested with white setae. FIGURE 25. Distribution of Erymanthus melanurus . Elytra: Elytral length to width ratio 2.02:1 to 2.15:1 (average 2.09:1); basal half light brown, apical half dark brown to black; punctation large, circular to slightly elongate-ovate, interstices half to same width as diameter of punctation, punctation in more or less regular rows; elytral base with black and flavous pilosity, apically partly with dense white and flavous pilosity; gibbosities pale, gibbosities A, B, C and D with dense white setal tuft, E with black setae. Legs: Light brown, sometimes dark markings on the femora, tibiae slightly darker. 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 very short; tegminal struts broadened until three-sevenths length and tapering lanceolate until tip; phallic tip very blunt; posterior side of pygidium rounded; processes of ventrite VI rather pointed. Distribution: Guinea , Togo , Congo , DR Congo , Uganda . Seasonal occurrence: Collected from March to April.
