Abstract

fetched live from OpenAlex

Chalcovietnamicus logunovi Yu, Maddison & Zhang, sp. nov. (ẄDZffiḋff) Figs 29–40, 63–65, 142 Type material. Holotype: ♁ (UBCZ; KYU-SAL401), MALAYSIA: Selangor, Ulu Gombak Field Station, 3.325°N, 101.753°E, 250 m, 16–19 May 2005, leg. W. Maddison, D. Li, I. Agnarsson & J. Zhang, WPM#05-026. Paratypes: 2♁ 2♀ (UBCZ; KYU-SAL402 ~405), same data as holotype. Other material examined. 1♀ (UBCZ; KYU-SAL406), same data as holotype. Etymology. The specific epithet is in honor of Dr. Dmitri V. Logunov (Manchester Museum, UK), who is an expert in this group, and has offered much assistance to the authors in the study of jumping spider taxonomy. Diagnosis. Males can be distinguished from C. daiqini and C. marusiki sp. nov. by the presence of a retrolateral hump on the distal part of embolus, and the rather large and deep groove around the apical extension of embolus (Figs 63–65). Females can be distinguished by the relatively large atria and the slightly rounded spermathecae (Figs 35–36). Description. Male. Habitus as shown in Fig. 29. Measurements of holotype (KYU-SAL401): carapace 1.80 long; abdomen 1.86 long; measurements of eyes: AME 0.40, ALE 0.26, PME 0.08, PLE 0.21; measurements of legs: I 3.58 (1.07, 0.79, 0.81, 0.53, 0.38), II 2.59 (0.85, 0.39, 0.52, 0.48, 0.35), III 2.67 (0.94, 0.44, 0.41, 0.59, 0.29), IV 3.08 (0.98, 0.49, 0.60, 0.67, 0.34); leg formula 1432. Endite with anterior lateral subtriangular extension. Color in ethanol (Fig. 29): 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 hollow longitudinal light mark on axis, and three pairs of light setal bands on each side of posterior part (Fig. 29). Palp as in Figs 33–34, 37–38: Cymbium slightly longer than palpal bulb, 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 and oblong embolic disc which hidden behind bulb, with retrolateral distal hump (RdH); small apical extension of embolus (aE) sticking out of wide and deep groove around itself; retrolateral tibial apophysis (RTA) straight, distal part digitiform. Female. Habitus as shown in Fig. 30. Measurements of paratype (KYU-SAL402): carapace length 1.74; abdomen length 1.86; measurements of eyes: AME 0.37, ALE 0.25, PME 0.06, PLE 0.21; measurements of legs: I 2.57 (0.81, 0.48, 0.52, 0.38, 0.38), II 2.36 (0.79, 0.36, 0.47, 0.41, 0.33), III 2.54 (0.78, 0.42, 0.41, 0.53, 0.40), IV 3.00 (0.98, 0.48, 0.56, 0.63, 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. 32); abdominal pattern like male, but more distinct. Vulva as in Figs 35–36, 39–40: copulatory ducts short, curved outward; spermathecae subspherical and wider than long, with accessory glands (AG) attached at its base. Natural history. Foliage dwellers. Distribution. Known only from the type locality.

Full frame distilled prediction

Teacher imitation

Not 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.
