Blackburneusstercorosus (Melsheimer, 1844) (Fig. 135-139) Aphodius stercorosus Melsheimer, 1844: 136; Horn 1870: 127; Horn 1887: 35; Jerath 1960: 63 (larval morphology); Woodruff 1973: 98; Ratcliffe and Paulsen 2008: 208. Aphodius (Koshantschikovius) stercorosus; Schmidt 1913: 150; Schmidt 1922: 230; Dellacasa 1988: 202. Blackburneusstercorosus; Gordonand Skelley 2007: 364. Typelocality. Pennsylvania [U.S.A.]. Type repository. Unknown to authors; type probably lost. Redescription. Length 3.0- 4.5 mm; oblong, convex, shiny, glabrous. Rufo-testaceous; epistome and pronotal disc dark brownish; elytra with more or less widened dark brownish cloudy discal spot; legs yellowish-brown to dark brown; antennal club testaceous. Head with epistome moderately convex on disc, regularly evenly punctured; punctation somewhat denser and coarser distally, sparser and more superficial medially; clypeus feebly sinuate at middle, round at sides, thinly bordered, edge glabrous; genae round, with extremely short near imperceptible bristles, faintly protrudingfrom the eyes; frontal suture very finely impressed, sometimes almost obsolete; front rather sparsely evenly punctured. Pronotum transverse, convex, dually punctured; large punctures, three to four times larger than small ones, dense and coarse on sides, lacking on disc; small punctures regularly scattered throughout, somewhat distinct on sides, more superficial on disc: lateral margins feebly arcuate, rather thickly bordered, edge glabrous; hind angles obtusely round; base faintly bisinuate. Scutellum flat, sparsely finely punctured. Elytra oval, feebly widened posteriorly, epipleural carina distinctly raised at shoulder, finely striate; striae distinctly punctured, feebly crenulate; interstriae flat, near imperceptibly sparsely punctured on disc; more distinctly punctured and finely microreticulate thus alutaceous on preapical declivity, dull at apex. Hind tibiae superiorapical spur regularly acuminate, somewhat shorterthan first tarsal segment; latterlonger than following three segments combined. Male: head somewhat less convex; pronotum more transverse lessdenselyand coarselypunctured on sides; foretibiae apicalspurstouter and downward curved; aedeagus Fig. 136-137. Female: head somewhat more convex; pronotum somewhat narrowed frontwardly, more coarsely densely punctured on sides; fore tibiae apical spur slender and almost straight. Material examined.

Coprophagous species found in several kinds of dung, from April to October; often attracted to light.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
