A new species of Elachiptera Macquart from the Galápagos Islands, Ecuador, and the taxonomic status of Ceratobarys Coquillett (Diptera: Chloropidae)
Bibliographic record
Abstract
Elachiptera cultrata sp. nov. is described from the Galápagos Islands, Ecuador. This species is most similar to the northern Neotropical species E. attenuata (Adams), except for the shape of the arista and the male genitalia. The monotypic genus Ceratobarys is synonymized with Elachiptera, and its type species C. eulophus (Loew) transferred to Elachiptera as E. eulophus comb. nov. The only morphological character that distinguishes the two genera is the presence of a long, apical, hind-tibial spur in Ceratobarys. Although this character defines some apparently monophyletic genera of Chloropidae, its presence and size are subject to homoplasy in other genera. The presence of a small hind-tibial spur in some species of Elachiptera, and the great similarity in other external and genitalic characters between Ceratobarys and some species of Elachiptera makes recognition of Ceratobarys untenable.

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; a candidate call from one teacher head, not a consensus.
