Bibliographic record
Abstract
Melanophilharmostes tuber Grebennikov, new species Figs 1–5. Type locality. Cameroon, Mt. Cameroon, 4.0681ºN, 9.0717ºE, 233m. Type material. Holotype (deposited in the Canadian National Collection of Insects, Arachnids, and Nematodes, Ottawa, Canada), female, “ CAMEROON, Mt. Cameroon, 4.0681, 9.0717, 233m, 28.xii.2015, sift. CM09, V. Grebennikov.”, “CNCCOLVG00009477”. Paratype (deposited in the Canadian National Collection of Insects, Arachnids, and Nematodes), not sexed, “ CAMEROON, Mt. Kupe, 4.8193, 9.7075, 1525m, 29.xii.2015, sift. CM13, V. Grebennikov.”, “CNCCOLVG00009488”. Description. Holotype maximal body length (in rolled position, Fig. 1A): 2.5 mm (paratype: 2.5 mm), maximal body width (Fig. 1): 2.2 mm (paratype: 2.3 mm). Head distinctly convex, clypeal disc gibbose. Interocular bridge completely subdividing each eye into smaller dorsal and larger ventral parts (Fig. 2E); antenna with seemingly 10 antennomeres (Fig. 2F, not dissected to make exact count); head, pronotum, and elytra with deep and dense microsculpture (horseshoe-shaped and comma-shaped), as well as with sparse, short, and distinct pilosity; surface of pronotum uneven, with bumps and depressions (Fig. 2A); each elytron with notable lateral longitudinal sharp carina interrupted in posterior part (Figs 2B, D); hind wings fully developed; distal fork of vein CuA present; distal expansion of vein MP 1+2 cannot be verified using single available wing (Fig. 2D). Male genitalia unknown. DNA data of holotype: MW899169 (COI) and MW845067 (28S); DNA data of paratype: MW899176 (COI), MW845087 (ITS2), and MW845074 (28S). Diagnosis. Within the Synarmostes group of four Afrotropical genera (including Madagascar and Comoros), this species can be immediately recognised by any of its four diagnostic characters: (1) head distinctly convex with clypeal disc gibbose (Fig. 2F), (2) bumpy pronotum, (3) notably developed longitudinal carina on each elytron, and (4) deep and dense microsculpture on the head, pronotum, and elytra. Distribution. This species is known from two Cameroonian localities about 100 km apart: Mt. Cameroon (233 m) and Mt. Kupe (1523 m). Natural History. Both specimens were collected by sifting forest leaf litter in rainforest. Derivation of name. The species epithet is the Latin noun meaning “a hump, bump, swelling, protuberance”, with reference to the peculiarly bumpy pronotum of the new species distinguishing it from all its congeners; it is used as a noun in apposition.

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.
