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.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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; both teacher heads agree on what is shown here.
