A revision of Biting Midges of the Subgenera Forcipomyia (Metaforcipomyia) and F. (Saliohelea) from Costa Rica (Diptera: Ceratopogonidae)
Bibliographic record
Abstract
The Costa Rican species of the subgenus Forcipomyia (Metaforcipomyia) Saunders are revised, primarily based on males. Fourteen new species are described and illustrated, F. (M.) pluvialis Malloch is redescribed, and a key to males and females is provided. One new species of the subgenus Forcipomyia (Saliohelea) Wirth & Ratanaworabhan is described and illustrated and F. (S.) leei Wirth & Ratanaworabhan is redescribed. Forcipomyia (Euprojoannisia) pechumani Bystrak & Wirth is transferred to the subgenus F. (Saliohelea). All adult F. (Metaforcipomyia) lack a hind tibial comb and males have antennal flagellomeres 5–8 fused and these are proposed synapomorphies of the subgenus. A truncate labrum is present in F. pluvialis, F. rivalis n. sp. and F. truncata n. sp. and is a derived feature indicating these species form a monophyletic group. We were unable to suggest a synapomorphy indicating the monophyly of F. (Saliohelea). Nearly all Costa Rican members of the subgenera F. (Metaforcipomyia) and F. (Saliohelea) are restricted to wet habitats and are excluded from the dry northwestern portion of this country. Eleven of the 15 new species described herein are present in the lowlands of Costa Rica, suggesting they are actually more broadly distributed to the north and/or south.

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.
