Abstract
Acantholycosa zonsteini sp. n. Figs 1–9 Acantholycosa? baltoroi (Caporiacco, 1935): Marusik et al. 2016: 7, figs 26–27 (♂, misidentification). Type material. Holotype ♂ (ZMMU), Russia, Khabarovsk Province, Slavyanka Vill., 1990 (S. Golovatch). Etymology. The species name is a patronym in honour of our friend and colleague Sergei L. Zonstein, the leading expert in Old World Mygalomorphae, Filistatidae and Palpimanidae, on the occasion of his 60th birthday (29th of April 2016). Diagnosis. The new species is most similar to A. levinae Marusik, Azarkina & Koponen, 2004 (Fig. 11), a species known from Altai, Russia. Both species have rather large paleal apophysis (Pa), bilobated tip of embolus and flat and broad embolic tooth (Et). The two species differ by the size of the embolic tooth, which is much larger in A. zonsteini sp. n. (Figs 1, 11), by the tip of embolus (rounded in A. zonsteini sp. n., and sharply pointed in A. levinae). The new species also has the retrolateral part of palea rounded, while in A. levinae it is angled. Additionally, the two species have different number of ventral tibial spines, four pairs in A. zonsteini (Fig. 3) and five pairs in A. levinae. Acantholycosa zonsteini sp. n. differs from A. baltoroi by having an embolic spine, the tip of the embolus bilobated (both lacking in A. baltoroi, Fig. 10), and a large paleal apophysis, which is small, spine-like in A. baltoroi (Fig. 10). Description. Male. Carapace 3.43 long, 2.64 wide. Total length 5.86. Coloration poorly visible due to bad preservation of the only specimen. Carapace blackish, with yellow median band and short white setae near the eye area. Lateral stripes yellowish, poorly visible. Eye area blackish. Abdomen dark brown with cardiac mark and white spots. Chelicerae dark brown with long white setae. Maxillae yellow, labium brown. Sternum dark brown, without stripes and spots. Leg I without pubescence. Spination of leg I: femur with 3 dorsal, 2 prolateral and 2 retrolateral spines; tibia with 1 prolateral, 1 retrolateral and 4 pairs of ventral spines; metatarsus with 1 prolateral, 1 retrolateral and 2 pairs of ventral spines. All leg segments dark brown, except for light brown coxae, with light spots and rings. Male palp as in Figs 1–2, 4–9. Cymbium with two claws. Tegular apophysis (Ta) small, without apical arm. Terminal apophysis (Te) wide and long, claw-shaped. Paleal apophysis (Pa) large, triangular-shaped. Embolus wide, with broad tooth at the base (Et) and bilobated tip. Female unknown. Note. The earlier record of A. baltoroi from Khabarovsk Province (Marusik et al. 2016) is based on misidentification of the single specimen here considered as the holotype. Distribution. Type locality only. Discussion. The new species belongs to the A. baltoroi -group, the only species group of Acantholycosa with the Holarctic distribution. It is known from Siberia and Western Nearctic (Marusik et al. 2004). Together with the new species described here, it encompasses five species: A. baltoroi (Caporiacco, 1935) (♂ ♀, Himalaya, Tibet and Eastern China), A. levinae (♂, Altai), A. solituda (Levi & Levi, 1951) (♂ ♀, Western Nearctic, from Alberta to Utah), A. sterneri (Marusik, 1993) (♂ ♀, Siberia from Kemerovo to Chita Area) and A. zonsteini sp. n. (♂, Khabarovsk Province). Below we provide an identification key to the males of Palaearctic species of A. baltoroi -group (females of two species are unknown).

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.
