Testing the monophyly of the tribe Aciliini and the phylogenetic position of the Afrotropical genus Aethionectes Sharp, 1882 (Coleoptera: Dytiscidae, Dytiscinae) based on larval morphology
Bibliographic record
Abstract
We describe the instar III larva of the Madagascar endemic diving beetle Aethionectes oberthueri (Rgimbart, 1895), including detailed morphometric and chaetotaxic analyses of the cephalic capsule, head appendages, legs, terminal abdominal segment and urogomphi in order to discover useful characters for distinguishing Aethionectes Sharp, 1882 larvae from those of other known Aciliini genera (Coleoptera: Dytiscidae, Dytiscinae) i.e., Acilius Leach, 1817, Graphoderus Dejean, 1833, Rhantaticus Sharp, 1882, Sandracottus Sharp, 1882, and Thermonectus Dejean, 1833. A parsimony analysis based on 94 larval characteristics was conducted using the program TNT. The larva of Aethionectes is similar in every way to those of the other Aciliini genera adding to the unique morphology of members of this lineage. Whereas Acilius larvae stand out from other genera, our parsimony analysis did not recover any clear phylogenetic position of Aethionectes within the tribe. A key of identification of instar III larvae of World Aciliini is provided.

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.
