Specimens examined: Holotype : N. Kamerun , Joh. Albrechtshöhe, L. Conradt S., Type , Schenkling det., Erymanthus ater m, Holotypus , Erymathus ater Hintz, 1905 , labelled by MNHUB 2012 (ZMB). Comment on type specimens: Hintz (1905: 308) describes one specimen from Johann Albrechts-Höhe, therefore the specimen of Zoologisches Museum Berlin ( ZMB ) is considered the holotype , fixed by monotypy ( ICZN 1999: Article 73.1.2).

Erymanthus ater : (A) Aedeagus ventral, (B) Phallus lateral, (C) Tegmen dorsal, (D) Spicular fork, (E) Pygidium, (F) Ventrite VI; (scale bars 1mm). Diagnosis: Erymanthus ater can be confused with E. revoili , E. horridus and E. pustulosus ; E. revoili has conical pronotal gibbosities and a conspicuous rasp-like punctation; E. horridus shows a longitudinal ridge in its pronotal groove and has a conical phallic tip; the tegminal struts of E. pustulosus are broadly furcate and the tips of tegminal lobes are blunt; E. ater is clearly recognizable by the long antennomeres 9–11. Length: ( 10 specimens measured) 10–14mm (average 11.75mm ). Head: Black; antennae brown; frons with two gibbosities; with whitish to yellow anteriorly directed pilosity; antennomere 2 longer than A3; antennomeres 9–11 longer than 1–8; with a large club. Pronotum: Pronotal length to width ratio 1.04:1 to 1.13:1 (average 1.08:1); black, pronotal arch lighter; apex sometimes with light markings; pronotal groove shallow, gibbosities protuberant; broadest in the middle; with long yellow-brown pilosity. Scutellum: Black; vested with white setae. Elytra: Elytral length to width ratio 2.13:1 to 2.47:1 (average 2.36:1); black with diaphanous markings; punctation fine, elongate-ovate, interstices wider than diameter of punctation, irregularly distributed; with dense posteriorly directed red brown to black pilosity; gibbosities with dense fine punctation (sometimes with dark setal tuft). Legs: Dark, sometimes basal part of meso- and metafemora lighter. Lower surface: Dark, with dense posteriorly directed white pilosity. Male genitalia, pygidium, ventrite VI: Tips of tegminal lobes pointed, tegminal lobes three-eighths length of tegmen; tegminal struts quite narrow, last one-fifth furcate; phallic tip blunt; posterior side of pygidium rounded, very slightly pointed; processes of ventrite VI pointed. Distribution: Senegal , Ivory Coast , Nigeria , Cameroon , Central African Republic , Congo . Seasonal occurrence: Collected from June to December.
