Phylogeny of Peyerimhoffia Kieffer, with the revision of the species (Diptera: Sciaridae)
Bibliographic record
Abstract
Abstract The genus Peyerimhoffia Kieffer (type-species Sciara vagabunda Winnertz), currently classified as a subgenus of Cratyna Winnertz (type-species Cratyna atra Winnertz) is redefined and its phylogeny studied by parsimony analysis. Cladistic analysis using sixty-four morphological characters from adult males of sixty-six ingroup and one outgroup species produced thirty most parsimonious cladograms. The strict consensus cladogram of these showed unambiguously that the type-species of Peyerimhoffia and the species currently referred to the Corynoptera crassistylata group form a monophyletic unit. The phylogenetic hypothesis obtained also suggested that Cratyna s.l. in its current concept is non-monophyletic and that Peyerimhoffia deserves generic status. The genus is Holarctic-Oriental in distribution and includes the following species, which are keyed and described or diagnosed: Peyerimhoffia alpina (Mohrig) (Austrian Alps, Italy, Spain, Canada: Quebec), P. calva sp.n. (Nepal), P. collina sp.n. (Russia: Altay region), P. crassistylata (Frey) (central and northern Europe, Altay region, Kurile Islands), P. curvata (Mohrig & Mamaev) (Russia: Tuva region), P. infera sp.n. (northern Europe), P. ioculatoria (Mohrig) (Nepal), P. menzeli sp.n. (northern Europe), P. obtusicauda (Strobl) (southern Europe), P. semicurvata (Mohrig) (Nepal, Burma), P. subcurvata (Mohrig) (Nepal), P. thula sp.n. (northern Europe), P. ultima sp.n. (Nepal), and P. vagabunda (Winnertz) (Europe, eastern Palaearctic). Plastosciara perniciosa Edwards, Hyperlasion curtipennis Edwards, and Plastosciara hybrida Mohrig & Mamaev are excluded, the former appearing more closely related to Epidapus Haliday, the latter two to Spathobdella Frey.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
