Type species. Scarabaeus prodromus Brahm 1790: 3, by subsequent designation.


Diagnosis. Body length 4.5-7.6 mm, elongate, somewhat flattened, black, elytra yellow-brown with variable dark maculations. Head smooth, lacking tubercles. Clypeus lacking teeth, weakly emarginate at middle, broadly rounded each side of median emargination, lacking fringe of setae. Head, pronotum and often elytra are sexually dimorphic. Pronotum lacking lateral setal fringe; with marginal line at base. Elytra lacking humeral tooth; intervals convex, often bearing setae. Metatibial apical spinules long and alternately unequal.

Distribution. Holarctic.
Composition. Worldwide, Melinopterus contains approximately 20 species, 3 of which occur in the New World.

Life History. Members of Melinopterus appear to be surface dung generalists as adults.
Larvae. The larva of M. prodromus is described in Ritcher (1966).
Status of Classification. Variability and sexual dimorphism of this genus causes confusion in identification of these species, as well as those of other genera (primarily Flaviellus and females of Drepanocanthoides).
