Monophyly, review, six new species and DNA barcode of micropterous Afromontane Afropictinus (Heteroptera: Aradidae)
Bibliographic record
Abstract
The micropterous East African flat bug genus Afropictinus Heiss, 1986 (Heteroptera: Aradidae: Mezirinae) is revised. In addition to the type and only known species A. congoensis (Hoberlandt, 1956) from Rwanda, four new species from Tanzania (A. castor sp. nov., A. hylas sp. nov., A. idas sp. nov., A. nauplius sp. nov.), one new species from the Democratic Republic of the Congo (A. kahuzianus sp. nov.), and one new species from Ethiopia (A. nabu sp. nov.) are described and illustrated. An identification key is presented to all seven nominal species of Afropictinus. DNA barcodes of 28 individuals of Afropictinus species were newly generated and together with 12 sequences of other Aradidae were made publicly available at dx.doi.org/10.5883/DS-AFROPICT. These mtDNA sequences were analyzed phylogenetically using Maximum Likelihood approach with 500 bootstraps. Obtained topology reveals a monophyletic Afropictinus with high statistical support (84%), although its sister group remains elusive. Both specimens of non-Tanzanian Afropictinus species included in the study (A. kahuzianus and A. nabu) were nested among Tanzanian congeners. The internal clades within Afropictinus, except for those at species and population level, had lesser statistical support. Despite of intense sampling, no Afropictinus species was found in mountain forests of geologically young (<2 Ma) volcanic highlands of the Ngorongoro-Kilimanjaro Volcanic Belt, which suggest reduced dispersal capacities.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
