Type species. Aphodius columbicus Harold, 1880 , here designated.

Diagnosis. Small or medium size species (length 3.5-6.0 mm), moderately convex, shiny, glabrous. Chestnut or dark brown, rarely black. Head with epistome evenly, coarsely, more or less densely punctured; clypeus angulately sinuate at middle, obtusely angulate at sides, with finely glabrous border; genae obtuse, not or near imperceptibly ciliate, protruding from the eyes; frontal suture finely impressed, not tuberculate; first segment of labial palps longer than second ( Fig. 69 View Figure 67-77 , 79 View Figure 78-88 ). Pronotum transverse, weakly convex, evenly more or less coarsely and densely punctured; lateral margins glabrous; hind angles widely truncate. Scutellum small, triangularly elongate, basally punctured. Elytra elongate, subparallel-sided or faintly widened posteriorly, denticulate or not at shoulder; striae rather deep, fine, superficially punctured, subcrenulate; interstriae moderately convex, sparsely punctulate. Fore tibiae distally tridentate and proximally serrulate on outer margin; upper side densely and more or less coarsely punctured. Hind tibiae with rather feeble transverse carinae on outer face, apically fimbriate with spinules elongate and irregularly unequal. Pygidium distinctly microreticulate, evenly, rather sparsely, not coarsely punctured; each puncture with a short recumbent hair; apical margin with few very elongate setae. Sexually dimorphic characters feebly stressed: males have head and pronotum relatively more transverse and less densely punctured, fore tibiae slender and more elongate with spur stouter and shorter. Aedeagus with parameres rather elongate, apically curved and more or less diffusedly pubescent. Epipharynx with anterior margin deeply sinuate at middle, round at sides; epitorma subconical; corypha with two prominent apical strong spiculae; pedia densely pubescent, with subserially arranged lateral stout chaetae; chaetopariae dense and moderately elongate.

Distribution. Meso- and South American regions.

Etymology. The name results from the combination of the genus name Gonaphodius and the suffix – oides [= having the form of]. The gender is masculine.
