Abstract
Orcevia zabkai Yu, Maddison & Zhang, sp. nov. (Ẹ氏ĸ尔¤) Figs 6, 332–352 Type material. Holotype: ♂ (UBCZ; KYU-SAL502), MALAYSIA: Sarawak, Adam Road, 1.336°N, 103.816°E, 10 m elev., 1–2 June 2019, leg. W.P. Maddison & Paul Ng, WPM#19-030. Paratypes: 1♂ (UBCZ; KYU-SAL503, # AS 19.0072), same data as holotype; 1♂ 2♀ (UBCZ; KYU-SAL511; KYU-SAL513; KYU-SAL522), same data as holotype. Other material examined. 1 juvenile (UBCZ; DNA-Voucher KYU098), same data as holotype. Etymology. The specific epithet is in honor of Dr. Marek Żabka (Siedlce University of Natural Sciences and Humanities), who has contributed greatly to the jumping spider taxonomy. Diagnosis. Males can be distinguished from O. sokoli (Prószyński & Deeleman-Reinhold, 2013) comb. nov. by the unbranched RTA (Fig. 347; vs. tip of RTA is bicuspid in O. sokoli) and the slender embolus (Fig. 348); females can be distinguished from O. sokoli by the starting part of copulatory duct that is fused to spermatheca, the relatively short accessory glands, with the ratio of length of AG to diameter of spermatheca as 1:3 ~ 1:2 (Fig. 352; vs. AG is obviously long, with the ratio of AG length to diameter of spermatheca ca. 3: 2 in O. sokoli). Description. Male. Habitus of holotype as shown in Fig. 338. Measurements of holotype: carapace length 3.23; abdomen length 2.87; measurements of eyes: AME 0.57, ALE 0.36, PME 0.08, PLE 0.29; measurements of legs: I 7.27 (2.12, 1.35, 1.80, 1.27, 0.73), II 5.05 (1.57, 0.92, 0.98, 0.99, 0.59), III 4.98 (1.61, 0.77, 0.96, 1.03, 0.61), IV 5.66 (1.73, 0.79, 1.31, 1.24, 0.59); leg formula 1423. Carapace dark, with rather dense pale setae overhead and almost no setae at flanks and posterior part; with some yellowish-brown setae between anterior lens; dorsal abdomen dark, with dense pale setae anteriorly and gradually thinning to rear, three oblique pale setal bands present on last two thirds of dorsal abdomen each side. Legs I and femora II–IV dark, other segments lighter-colored; pale setae present from distal femora to tibia dorsally, and a little on distal two thirds of metatarsi I–II. Palp (Figs 340–342): palpal bulb with obvious retrolateral constriction between tegular lobe and main part of tegulum; embolus with many small grooves on basal part along direction of embolic extension, one row of saw-like denticles present on median part of embolus; tip of embolus cylindric (Fig. 351); RTA basally wide, almost aequilatus in basal half, then gradually narrowed to tip; one small bump present on ventral side of base of RTA (Fig. 346). Female. Habitus as shown in Fig. 339. Measurements of paratype (KYU-SAL513): carapace length 3.07; abdomen length 3.18; measurements of eyes: AME 0.55, ALE 0.36, PME 0.08, PLE 0.29; measurements of legs: I 5.23 (1.57, 1.10, 1.15, 0.80, 0.61), II 4.68 (1.55, 0.95, 0.93, 0.76, 0.49), III 4.92 (1.60, 0.79, 1.00, 0.96, 0.57), IV 5.85 (1.79, 0.86, 1.34, 1.18, 0.68); leg formula 4132. Distribution of pale setae and body color like male, but pale setae relatively sparse, especially on cephalon; pale setae reduced on face; patellae and tibiae III–IV relatively darker than male. Epigynum (Fig. 343–344): atria subcircular, close to each other; outer edges of atria stretching upward, forming one shallow and indistinct concave area above atria. Vulva (Fig. 345): copulatory ducts long and relatively wide, downwards extended first, then turning upwards and forming a loop at ventral side of spermathecae (Fig. 344); spermathecae slightly darker than copulatory ducts; accessory glands pointing upwards, partly covered by fertilization ducts in dorsal view. Natural history. Tree trunk dwelling spider. Distribution. Malaysia (Sarawak).

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; both teacher heads agree on what is shown here.
