Abstract
Abstract The phylogenetic relationships of members of the hydroporine tribe Bidessini (and particularly of the Neotropical endemic genus Hydrodessus J. Balfour-Browne, 1953) are investigated based on a cladistic analysis of larval characteristics, including 26 Hydroporinae species in 25 genera. For this purpose, the larvae of Hydrodessus latotibialis Miller, 2016 are described for the first time including detailed morphometric and chaetotaxic analyses of the cephalic capsule, head appendages, legs, last abdominal segment and urogomphi. Larval morphology supports a monophyletic origin of the Bidessini based on the absence of the primary pore ABc, a unique feature within Hydroporinae. Hydrodessus was recovered as sister to other Bidessini studied, being characterized by several unique character states. This result supports a previous hypothesis of a basal position of this genus within Bidessini based on adult characters. The presence of natatory setae on femur, tibia and tarsus could represent an adaption to life in lotic environments.

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
