Three new species of Neotropical Tropisternus Solier (Coleoptera: Hydrophilidae)
Bibliographic record
Abstract
The water scavenger beetle genus Tropisternus Solier, 1834, is one of the most common and recognizable taxa of aquatic beetles in the New World. As presently defined, the genus contains 60 species (Hansen 1999, Short & Hebauer 2006) and ranges from northern Canada to the southern tip of South America. The senior author (PJS) conducted a full revision of this taxonomically difficult genus for his PhD dissertation nearly fifty years ago (Spangler 1960). For the next several decades, PJS continued to update, revise, correct, and incorporate new material into this massive work. This paper makes available three new names of Tropisternus in preparation for the eventual publication of this authoritative treatment of the genus. It should be noted for those using the keys given in Spangler (1960) that the interpretation of some of the names proved incorrect following the examination of types; the key should be used with extreme caution particularly for Neotropical taxa.

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.
