Abstract
Philetus kitsi sp. nov. (Figs 1–5) urn:lsid:zoobank.org:act: 2E951D56-6D9E-4FF2-89B5-E3B88BC411EE Type material. HOLOTYPE, ♂ labelled: “ CANADA: YT: Richardson/ Mtns., 67°46ʹ43.22ʺN / 136°41ʹ55.86ʺW, 850m,/ 29.vii.2019, Malaise trap,/ shrub tundra, JK19-075,/ J.H. Kits, CNC1614247 ”; “HOLOTYPE/ Philetus kitsi / Cumming & Brooks [red label]” [dissected terminalia in microvial]. Type deposited in the Canadian National Collection of Insects, Ottawa, Canada (CNC). Diagnosis. Philetus kitsi sp. nov. is characterized by male terminalia with elongate simple cercus connected to lengthened ventral subepandrial lobe with digitiform apex (Fig. 3) and thumb-like preapical medially-directed process (Fig. 5), large epandrial lobe with posteriorly hooked dorsal process, and hypandrium with dorsally prolonged narrow median apical process (Figs 3, 4). In addition, the longer more narrowly produced apex of the antennal postpedicel (similar to P. memorandus) separates this species from most specimens of P. schizophorus. Description. Male. Body length 3.5 mm, dark brownish grey, covered with silvery grey tomentum (Fig. 1). Antenna dark brown to black; postpedicel pyriform with apex narrowly produced towards stylus. Legs brown to greyish brown. Wing hyaline with brownish veins. Halter brownish white. Terminalia: hypandrium with long hook-shaped apical rods arising above base of long, dorsally directed, narrow median apical process (Fig. 3); postgonite projected dorsally as wide rounded lobe; phallus tubular, apex partially desclerotized and slightly expanded in dorsal view (Fig. 4); anterodorsal margin of hypandrium partially fused with anteroventral margin of epandrium; epandrial lobe large with series of short setae on outer and inner margins and posteriorly hooked dorsal process; ventral subepandrial lobe lengthened, shiny, with digitiform apex (Fig. 3) and thumb-like preapical medially-directed process (Fig. 5); ventral subepandrial lobe connected basally to cercus; medial subepandrial lobe absent; cercus elongate, simple, without bifid apex, rounded apically. Female. Unknown. Distribution and seasonal occurrence. Known from shrub tundra in the Richardson Mountains of the Yukon Territory, Canada (Fig. 2). The single known male was collected at the end of July. Etymology. This species is named in honour of our colleague, Dr. Joel H. Kits (CNC), who collected the only known specimen of this new species. Remarks. Based on the form of the male terminalia and the shape of the postpedicel (see key couplet 1 below), P. kitsi sp. nov. appears more similar to P. memorandus than to P. schizophorus. However, it differs from both these species in the habitat occupied, i.e., shrub tundra rather than montane and coastal forests. Cumming et al. (2016, Appendix) listed several undetermined female specimens of Philetus, including three in particular from the Yukon Territory (two from the Dempster Highway taken on tundra and one from Whitehorse). Some of these Yukon specimens possibly represent females of the new species described here. Unfortunately because of their older age and method of capture (from pan and flight intercept traps) they are unlikely to yield mitochondrial DNA barcode (COI) sequences, which could help confirm their species identities.

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.
