Abstract
Sculpteremaeus olszanowskii sp. nov. (Figs 1–4) Diagnosis. Adult. With character states of Sculpteremaeus gen. nov. Length 730-830. Translucent amorphous cerotegument present. Body surface with distinct longitudinal and transverse tubercles and short ridges on notogaster, and short transverse ridges in interlamellar region. Surface of all leg femora, podosomal region, ventrolateral parts of ventral plate and region close to pedotectum I with striae. Pair of ridges extending from close to margin of rostrum posteriorly to level of rostral setae. Lamella extending from bothridium anteriorly to level of paired ridges. Small area of notogaster, posterior of interrupted dorsosejugal scissure, with weak folds laterally. Tutorium 82–86 long. Small notogastral bulge present anterior of lyrifissure ia. Notogastral setae (16–24) thin, roughened. Subcapitular tectum of mentum covering base of seta m. Dorsoparaxial porose area on femora I-IV elongated; on trochanters III, IV oval. Ventroproximal porose area on all tarsi and ventrodistal porose area on all tibiae oval. Porose areas of tarsi, tibiae and femora slightly concave. Tarsus I with 20 setae. Description of adult. Measurements. Body length: 796 (holotype: female), 730, 763, 830 (three paratypes: male, male, female, respectively); notogaster width: 415 (holotype), 398, 415, 431 (three paratypes). Females larger than males. Integument (Figs 4A, F). Body color of preserved specimens light brownish. Body covered by translucent amorphous cerotegument including microgranules. Body surface with general porosity (visible under high magnification) and distinctly sculptured by tubercles and short ridges. Surface of all leg femora, podosomal region, ventrolateral parts of ventral plate and region close to pedotecta I-II with striae. Prodorsum (Figs 1A, C; 4A, C-E). Rostrum broadly rounded, with submarginal ridge along lateral margin of rostrum. Lamella longer than half of prodorsum, thin, with small quadrangular cusp. Weak, transverse ridge extending between lamellae at level of acetabulum I (Figs 1A, 4A). Tutorium (82–86), small, poorly visible. Rostral seta (36–41) tapered, slightly barbed. Weak (sometimes interrupted) pair of short ridges extending from insertions of rostral setae posteriorly; medial ridge present or not. Lamellar setae (28–32) slightly barbed, inserted slightly anteroventrally on lamellar cusps. Interlamellar seta (20–24) acuminate, slightly barbed. Exobothridial seta (6–8) acuminate, thin, smooth. Bothridial seta (28–32) globose, with minute stalk and short, globular, barbed head. Notogaster (Figs 1A, C; 2A; 4A, C). Elongate oval in shape. Small area of notogaster, posterior of interrupted dorsosejugal scissure, without sculpturing, rounded, indistinct, with weak folds laterally. Small humeral bulge present anterior of lyrifissure ia. Notogastral setae (16–24) thin, roughened. Notogastral lyrifissures and opisthonotal gland openings distinct. Gnathosoma (Figs 2B, C, D). Subcapitulum longer than wide (164–168 × 123–131). Subcapitular seta (28–32) acuminate, roughened. Subcapitular mentum with or without weak transverse ridge posteromedially. Adoral seta (24–28) acuminate, barbed. Palp length 94–102. Postpalpal seta not observed. Chelicera (length 172–176) with two acuminate, barbed setae (41–45). Epimeral and lateral podosomal regions (Figs 1B, C). Epimeral setae (1b, 1c, 3b, 28–32; 1a, 2a, 3a, 4a, 4b, 16–24) thin, roughened. Discidium triangular. Short ridge extending posteromedially from discidium. Pair of ridges present or not posterior of anal plates. Anogenital region (Figs 1B, C; 2A; 4B, C). Genital (16–24), aggenital (16–24), anal (20–24) and adanal (20– 24) setae acuminate, thin, roughened. Adanal lyrifissures angled towards anal plates anteriorly, located close to anal plates. Legs (Figs 3 A-D; 4H, I). All claws slightly barbed on dorsal side. Dorsoparaxial porose area on femora I-IV elongated; on trochanters III, IV oval. Ventroproximal porose area on all tarsi and ventrodistal porose area on all tibiae oval. Porose areas on femora, tibiae and tarsi slightly concave. Formula of leg setae and solenidia: I (1-4-3- 4-20) [1-2-2], II (1-4-3-4-16) [1-1-2], III (1-3-2-3-15) [1-1-0], IV (1-2-2-3-12) [0-1-0]; homology of setae and solenidia given in Table 1. Famulus of tarsus I short, erect, blunt, located between solenidia ω 1 and ω 2. Setae s on tarsus I non-eupathidial. Solenidion ω 1 on tarsus I, ω 1 and ω 2 on tarsus II of medium size, bacilliform; ω 2 on tarsus I, φ 1 on tibia I and φ of tibia II long, acuminate; φ 2 on tibia I of medium size rod-like; other solenidia very short, bacilliform. Leg segment mean length and ratio of leg length to body length of one paratype specimen given in Table 2. Note: Roman letters refer to normal setae, Greek letters to solenidia (except ɛ = famulus). Single prime (’) marks setae on the anterior and double prime (”) setae on the posterior side of a given leg segment. Parentheses refer to a pseudosymmetrical pair of setae. Material examined. Holotype (female) and 5 paratypes: USA, California, Riverside County, Santa Rosa Mountains, ~ 7 miles (11 km) south of junction with Highway 74, elevation 6200 ft (1890m) a.s.l., 33.32.587N, 116.28.948W, from sandy soil-litter in chaparral, 28 April 2002 (M.C. Hedin, P. Paquin & J. Starret). Additional material with the same collection data: four adults (sex not identified). Type deposition. The holotype and one paratype are deposited in the collection of the National Museum of Natural History, Smithsonian Institution, Washington, DC, USA (currently housed with the U.S. Department of Agriculture collections in Beltsville, Maryland); 1 paratype is deposited in the Canadian National Collection of Insects, Arachnids and Nematodes, Ottawa, Canada, and three paratypes are deposited in the collection of the Tyumen State University Museum of Zoology, Tyumen, Russia. Additional material: two adults (dissected on slides) in the personal collection of Roy A. Norton. Etymology. This species is named in honor of our esteemed colleague, Prof. Dr. Ziemowit Olszanowski (Adam Mickiewicz University, Poznań, Poland), who died in 2019. Ziemowit contributed significantly to our knowledge of Oribatida, especially Crotonioidea, globally.

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; both teacher heads agree on what is shown here.
