Abstract
Rudolfina pauca sp. nov. urn:lsid:zoobank.org:act: F085E96F-6CCB-49B0-83B8-503F18F1B472 Figs 16–17, 21C Etymology The species name is the Latin for ‘few’. Compared to the closely related R. exuberata sp. nov., which occurs throughout the Neotropical region and has been collected at over a hundred different sites, R. pauca sp. nov. has been infrequently collected and remains known from only five sites in Mexico and Guatemala. Material examined Holotype MEXICO • ♂; México, 1 mi. NE of Tenancingo; 7100 ft a.s.l.; 31 Aug.–6 Sep. 1971; A. Newton leg.; oak-pine-madrono, human dung; FMNH debu01086244. Paratypes GUATEMALA – San Marcos • 1 ♀; San Antonio Sacatepéquez; 14°58′ N, 91°44′ W; 8000 ft a.s.l.; 29 Sep. 1986; M.J. Sharkey leg.; DEBU. MEXICO – Hidalgo • 1 ♂, 1 ♀; 4 mi.

SW of Tenancingo, at km 52¼; 7100 ft a.s.l.; 31 Aug.–6 Sep. 1971; A. Newton leg.; oak-juniper, human dung; DEBU • 2 ♂♂, 1 ♀; same collection data as for preceding; UNAM. – Morelos • 1 ♀; 8 mi.

Head with 4 interfrontal setae and row of 8–10 small setulae on inner margin of orbital plate. Gena with 1 strong seta and 8 smaller setulae. Acrostichal setulae in 6–8 rows. Costagial seta extending to humeral break; second costal sector shorter than third (20:35); length of M 1 between crossveins dm-cu and r-m 1.2 × dm-cu; CuA 1 stub vein ~2.0 × M 1 stub vein. Male mid femur with 4–5 weak setae in ventrobasal cluster. Male mid tibia with ventral comb of 11–13 robust setae on apical ½. MALE ABDOMEN (Fig. 16). Sternites 3–4 evenly haired. Posterior margin of sternite 5 with lobes elongate, projecting posteriorly; emargination extending anteriorly ~¼ length of sternite, ~¼ width of sternite at posterior margin. Transverse part of sternite 6 weakly arcuate. Epandrium with 2 long ventrolateral setae and scattered setulae; subanal plate narrowly continuous below anal opening. Surstylus (in lateral view) trilobed, with anterior lobe rounded and bare, middle lobe small, rounded and with 4–6 distal setae apically, and posterior lobe posteriorly projecting and rounded, with 1 large, flattened seta and 2–3 regular setae apically. Cercus small and conical, projecting posterolaterally, with 2 apical setae. Postgonite slightly capitate or oar-shaped, with apex ventrally emarginate; 3–4 setulae present along dorsal surface. Dorsal sclerite of distiphallus (Fig. 16 D–F) without swellings and not extending beyond apex of acrophallus. FEMALE ABDOMEN (Fig. 17). Posterior margin of tergite 7 medially emarginate. Medial part of tergite 8 elongate, rectangular (length ~3.0× width) and poorly sclerotized; overlapping basal projection of epiproct. Epiproct tulip-shaped, with elongate narrow anterior extension. Cercus reduced, shorter than apical flattened seta; fused anterolaterally to epiproct. Spermathecae acorn-shaped, with a small, smooth distal bulb, a wrinkled medial section and a smooth basal section; paired spermathecae with stems as long as spermatheca; common duct of pair short, ~1/6 length of stems.

How this classification was reachedexpand
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.
