Diagnosis. Similar to M. sulphurizona (Table 2), but this species is morphologically distinctive through its mostly white tergite 6 (Figs. 5, 12), in addition to the usual white tergite 5. Other species have the anterior margin of tergite 6 white, but not to the extent found in M. albizona. Additionally, in this species, the left hypandrial process is about one-half the length as in the other species (except M. reductizona) (Figs. 10, 11). M. albizona keys to M. sulphurizona in Borgmeier’s key to Group VIII species of Megaselia, and was part of Borgmeier’s concept of that species (one paratype of M. sulphurizona from Palo Alto, California is M. albizona). M. albizona differs from all other white-belted species by at least 9% (Fig. 34, Table 1). The specimens of this species are in BOLD as BOLD:AAP4680. Distribution. Western North America. Besides our specimens from California and Colorado, USA, there are 14 additional specimens of this species in the BOLD database from southern British Columbia, Canada, and Utah, USA, that were used in the molecular analyses. Etymology. From Latin for white (albi-) and belt (zona), referring to the white tergites 5 and 6.
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.
How this classification was reachedexpand
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.
