First record of the genus <i>Shannoniana</i> and <i>Trichoprosopon</i> aff<i>. castroi</i> (Diptera: Culicidae) in Peru
Bibliographic record
Abstract
This study reports the first records of the genus Shannoniana Lane & Cerqueira, 1942 and Trichoprosopon aff. castroi Lane & Cerqueira, 1942 in Peru, both belonging to the Sabethini tribe of mosquitoes. Fieldwork was conducted in the Cerro Adobe conservation center in the Amazonas region, where ovitraps were used to collect mosquito larvae, which were then reared in the laboratory for identification. Morphological and molecular analyses confirmed the presence of these species, with Shannoniana showing differences from previously described species, and Trichoprosopon aff. castroi being recognized as a new record of this species for Peru. Phylogenetic analysis of COI sequences revealed 3 distinct genetic lineages, supporting the monophyly of Sabethini but indicating inconsistencies in the internal relationships within the genus Trichoprosopon. This work expands the known diversity of Sabethini mosquitoes in Peru and underscores the value of molecular tools in resolving taxonomic challenges in mosquito studies.

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.
