Abstract
INTRODUCTION: Pintomyia (Pifanomyia) longiflocosa is an endemic species from Colombia, found between the central and eastern Andes, and reported as one of the primary vectors of cutaneous leishmaniasis in coffee-growing zones of the country. This species is classified in the Townsendi series and can only be identified by the morphology of the male adults. OBJECTIVE: To determine the potential use of the fourth larval stage of the vector Pi. longiflocosa in morphological taxonomy based on the description of its chaetotaxy. MATERIALS AND METHODS: Pintomyia longiflocosa adults were captured in Campoalegre, Huila, and reared in the Entomology Laboratory at the Colombian Instituto Nacional de Salud. To identify the setae found in each corporal segment, 15 fourth-instar larvae were mounted on microscope slides using Canadian balm after being cleared with 10 % potassium hydroxide and saturated phenol. Additionally, five specimens were prepared for their observation by scanning electron microscopy. RESULTS: Based on the description of Pi. longiflocosa, we established that all species of the subgenus Pifanomyia so far described have the same antennal morphology and clavate setae along their body. However, various setae present in Pi. longiflocosa are absent in Pi. youngi, suggesting differences among the larvae of the Townsendi series. CONCLUSIONS: These results support the potential importance of morphological characters from the fourth larval instar, such as antennal morphology and chaetotaxy, specifically in closely related species that are cryptic in their adult stages.

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 it
