Bibliographic record
Abstract
Homocoprini tribe nov. urn:lsid:zoobank.org:act: A86B4671-86B5-41A2-B468-611826BCD7C9 Type genus Homocopris Burmeister, 1846, present designation. Differential diagnosis The only group of Scarabaeinae with a lateral pronotal carina combined with a setose elytral underside. Description Typical tunneler overall body shape. Size moderate to large; secondary sexual characters present and located on dorsum of head and pronotum; integument rather thin and flexible; antennal club elongate oval, symmetrical; internal surface of first segment of antennal club pubescent; distal edge of epipharynx straight; anterior pronotal membrane covering entire width of head insertion; lateral pronotal declivity with a strong carina connected to the lateral pronotal edge anteriorly, surface between carina and lateral edge flat and upright (slightly concave and overlapping only in A. achamas); posterior portion of pronotal lateral edge at most slightly sinuate; elytra with eight visible striae, stria eight absent or vestigial in some specimens of A. achamas (Fig. 62), stria 9 absent on basal fifth, distinct from stria 10 throughout; elytral internal surfaces with long semi erected setae; tarsal claws present; meso and metatibiae with four edges in mid cross section, expanding from base to apex and lacking transverse ridges on external surface; hindwings with AA3 connected to Cu and RP1 narrow and sharply defined throughout; apodeme of metasternalmetacoxal membrane present; unguinotarsal axillary lamellae present; medial endophallite absent. Genera included Andinocopris gen. nov. and Homocopris Burmeister, 1846.

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.
