Aphodius baileyi Skelley and Gordon, 2002: 85 .

Scabrostomus baileyi ; Gordon and Skelley 2007: 531.

Type locality. 2.7 mi S. Jct. Rt. 19 on New Hope Road, Sedgefield Plantation, Thomas Co., Georgia, U.S.A.

Type repository. Florida State Collection of Arthropods, Gainesville, Florida, U.S.A. (paratype examined).

Redescription. Length 3.0–4.0 mm; elongate, convex, shiny, shortly pubescent. Dark brown; clypeal margin. anterior angles of pronotum, legs and antennal club reddish brown. Head with epistome slightly convex medially, granulate throughout; clypeus faintly sinuate at middle, broadly round at sides, distinctly bordered, edge reflexed, glabrous; genae obtusely round, rather sparsely ciliate, moderately protruding from the eyes; frontal suture trigibbous; front coarsely not closely punctured, most punctures with short recumbent hairs. Pronotum transverse, convex, faintly alutaceous thus moderately shiny, irregularly not closely punctured, mostly the lateral punctures with short recumbent hairs; lateral margins weakly arcuate, distinctly bordered, edge glabrous; hind angles obtuse; base distinctly bordered. Scutellum irregularly coarsely punctured on basal half. Elytra oval elongate, convex, faintly alutaceous thus moderately shiny, deeply striate; striae narrow, superficially not closely punctured, not crenulate; interstriae convex, bearing laterally two longitudinal rows of distinct shortly pubescent punctures. Hind tibiae superior spur shorter than first tarsal segment; latter as long as following two segments combined. Male: inferior spur of middle tibiae less than half shorter than superior and obliquely truncate apically; aedeagus Fig. 2–3 . Female: inferior spur of middle tibiae slender, straight, and acuminate.
