REVISION OF THE NEARCTIC SPECIES OF <i>LAUXANIA</i> (DIPTERA: LAUXANIIDAE)
Bibliographic record
Abstract
Abstract The North American species of Lauxania Latreille are revised. The genus contains five Nearctic species: L . albiseta Coquillett, L . glabrifrons sp.nov ., L . kafarista sp.nov ., L . nigrimana Coquillett, and L . shewelli sp.nov . All Nearctic species are illustrated and keyed. Consistent genitalic differences between Nearctic and Palaearctic specimens of the species usually identified as Lauxania cylindricornis (Fabricius) justify the recognition of the Nearctic specimens as a distinct species ( L . shewelli ). The male genitalia of Lauxania represent two types: the apparently plesiomorphic type has a simple rodlike phallapodeme, membranous phallus, and pointed unbranched postgonites; the apomorphic type has the phallapodeme expanded into a sclerotized hood surrounding the base of the phallus, a convoluted sclerotized phallus, and branched postgonites. These two genitalic types also occur in the related genus Calliopum Strand, which provides strong evidence that these genera, as currently recognized, may not be monophyletic relative to one another.

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.
