Comment on the type specimens: Erymanthus horridus : Westwood made no mention of type specimens in his description of E. horridus therefore the single type specimen held in the Oxford University Museum of Natural History has been designated as the Lectotype . Erymanthus horridus ab. purpureoniger : Murray (1867) mentioned three specimens in his description of var. purpureoniger though did not designate any of them as a holotype . All purpureoniger type material are therefore considered syntypes ( ICZN 1999: Article 73.2) and available for lectotype designation ( ICZN 1999: Article 74.1). Others: La Maboké, R. C.

Kossou— Yamoussokro ( Côte d'Ivoire ), 15-Gen-1972 , legit: A. Bondinelli ( MZUF ). Diagnosis: Erymanthus horridus can be confused with E. revoili , E. ater and E. pustulosus . Erymanthus revoili has the pronotal gibbosities conical and a conspicuous, rasp-like, coarse punctation. Erymanthus pustulosus has a blunt phallic tip and blunt processes of ventrite VI. In E . ater the antennomeres 9–11 are longer than the antennomeres 1–8. Erymanthus horridus is recognizable by the longitudinal ridge in the pronotal groove, the conical phallic tip and the strongly pointed tips of ventrite VI. FIGURE 20. Erymanthus horridus : (A) Aedeagus ventral, (B) Phallus lateral, (C) Tegmen dorsal, (D) Spicular fork, (E) Pygidium, (F) Ventrite VI; (scale bars 1mm). Length: ( 37 specimens measured) 15–24mm (average 19,05mm). Head: Black, antennae lighter (testaceous); frontal umbo with irregular structure (deep grooves and wrinkles); with isolated flavotestaceous pilosity. Pronotum: Pronotal length to width ratio 0.97:1 to 1.14:1 (average 1.04:1); black; gibbosities conspicuously elevated, but smooth; pronotal groove with longitudinal ridge; with fine punctation; with flavotestaceous pilosity. Scutellum: Black; smooth in the middle, with laterally directed flavotestaceous setae. Elytra: Elytral length to width ratio 2.05:1 to 2.53:1 (average 2.31:1); black, sometimes with testaceous markings (especially on gibbosities); with fine, circular and isolated punctation in the basal half, interstices at least twice as wide as diameter of punctation, irregularly distributed; with isolated flavotestaceous pilosity; gibbosities yellow to red-brown, with brown to black setae. Legs: Coxae, femora and tibiae dark brown to black. Lower surface: Black, sometimes brown with yellow lateral spots; with dense white pilosity. Male genitalia, pygidium, ventrite VI: Tips of tegminal lobes blunt, tegminal lobes one-fourth length of tegmen; tegminal struts broadened until three-fourths length then tapering until furcate tip; phallic tip conical; posterior side of pygidium rounded; processes of ventrite VI extremely pointed. Distribution: Guinea , Ivory Coast , Ghana , Togo , Benin , Nigeria , Cameroon , Central African Republic , Gabon , Congo , DR Congo , Zambia . Seasonal occurrence: Collected from January to December.
