Etymology. The specific epithet is in honor of Dr. Yuri M. Marusik (Magadan, Russia), who has made great contributions on the taxonomy of Salticidae. Diagnosis. It can be distinguished from other congeners by the concave back side of embolus (Fig. 68) (vs. not concave), the small epigynal atria and kidney-shaped spermathecae (Fig. 59; vs. epigynal atria relatively large, spermathecae relatively oval in other species). Description. Male. Habitus as shown in Fig. 47. Measurements of holotype (KYU-SAL410): carapace length 1.72; abdomen length 1.55; measurements of eyes: AME 0.38, ALE 0.24, PME 0.04, PLE 0.18; measurements of legs: I 2.94 (0.88, 0.56, 0.66, 0.52, 0.32), II 2.45 (0.79, 0.41, 0.47, 0.47, 0.31), III 2.50 (0.86, 0.35, 0.49, 0.50, 0.30), IV 2.51 (0.85, 0.34, 0.54, 0.48, 0.29); leg formula 1423. Endite with anterior lateral subtriangular extension. Color (Figs 41–43): Body dark, covered with dense khaki setae except for face, palp and tibia I, these parts conspicuously black compared to other body parts; dorsal abdomen with indistinct longitudinal light mark on axis, and three pairs of light setal bands on each side of posterior part, the posterior pair connecting to each other (Fig. 43). Palp as in Figs 51–53, 56–57: Cymbium slightly longer than palpal bulb in length, cymbial process (CyP) present, slightly visible in ventral view of palp; tegular lobe wide and stout, distal part prolaterally pointed; short embolus sticking out of large irregular embolic disc, embolic disc hidden behind bulb, with back keel (bK) extending to distal part; embolus concave on back side (Figs 66–69); small apical extension of embolus (aE) sticking out of wide and relatively deep groove around itself (Fig. 68); retrolateral tibial apophysis (RTA) straight, digitiform distally. Female. Habitus as shown in Fig. 48. Measurements of paratype (KYU-SAL472): carapace length 1.61; abdomen length 1.68; measurements of eyes: AME 0.38, ALE 0.22, PME 0.05, PLE 0.19; measurements of legs: I 2.25 (0.73, 0.38, 0.51, 0.34, 0.29), II 2.04 (0.69, 0.35, 0.40, 0.33, 0.27), III 2.19 (0.79, 0.40, 0.39, 0.41, 0.20), IV 2.42 (0.76, 0.33, 0.50, 0.48, 0.35); leg formula 4132. Body form and color like male, but without anterior lateral subtriangular extension and present central setal tuft on sternum (Fig. 50); abdominal pattern like male, but more distinct. Vulva as in Figs 54–55, 58–59: Copulatory ducts short, curved outward; spermathecae kidney-shaped, with accessory glands (AG) attached at their base. Natural history. Mainly foliage-dwelling; sometimes can be found on tree trunks. 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.
