The first fossils of Alloraphes (Coleoptera: Staphylinidae: Scydmaeninae) described from Miocene Dominican amber
Bibliographic record
Abstract
Alloraphes Franz, 1980 is a small Neotropical genus (14 species) of Scydmaeninae (Coleoptera: Staphylinidae) beetles. Alloraphes are typically discriminated from the morphologically similar Stenichnaphes Franz via their aedeagal characteristics. Consequently, female members of both genera are often difficult to correctly place. Here we describe the first fossil species of Alloraphes in amber, and document its presence on the island of Hispaniola during the Miocene. Two individuals of new species Alloraphes cantusfurca sp. nov. are morphologically described using CT-scan data and microscope imagery. As the first known fossil member of the genus, A. cantusfurca provides a vital calibration point for future phylogenetic analysis and extends the temporal and geographic range of the genus. The implications for the biogeography of related taxa are also discussed.

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.
