Genus Oxyomoides new genus

Type species. Aphodius sepultus Cartwright, 1944 .

Diagnosis. Small species (length 3.0–4.0 mm), weakly elongate, convex, dull or weakly shiny, pubescent. Dark brown. Head with epistome granulate throughout; clypeus weakly sinuate at middle, round at sides, glabrous; genae protruding from the eyes; frontal suture with three more or less distinct tubercles; front coarsely, not closely punctured, punctures shortly setigerous. Pronotum convex, transverse, coarsely, more or less densely, somewhat irregularly punctured, punctures mostly on sides shortly setigerous; lateral margins glabrous; hind angles obtuse; base bordered or not. Scutellum small, triangular, coarsely punctured basally. Elytra convex, weakly elongate, subparallel-sided, deeply striate; striae crenulate or not, with subcordiform, geminate or simple punctures; interstriae more or less strongly convex, sometimes subcarinate and sharply finely margined on each side, dually longitudinally serially punctured, punctures with more or less elongate recumbent hairs. Hind tibiae apically fimbriate with spinules rather short, stout and irregularly alternately unequal. Pygidium distinctly alutaceous, superficially irregularly punctured, punctures with elongate recumbent hairs. Sexual dimorphism shown in males mostly by inferior spur of middle tibiae shortened and apically truncate. Aedeagus with elongate parameres, apically with more or less elongate thin membranous appendages. Epipharynx with anterior margin straight; epitorma guttiform; corypha not protruding from the anterior margin and with a clump of apical celtes rather short; pedia pubescent, with lateral rather elongate spines subserially arranged; chaetoparia moderately elongate and moderately dense.

Distribution. Southern United States.

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