Maddisonia Zabka 2014, gen. nov.
Bibliographic record
Abstract
Maddisonia gen. nov. Etymology. The name is proposed for Prof. Wayne Maddison (UniversitY of British Columbia, Vancouver), the world authority in salticid taxonomy, biogeography and evolution. The name is feminine in gender. Type species: Maddisonia richardsoni sp. nov. Diagnosis. Small/tiny spiders. Embolus large, cork-screwlike. In some species a projection at the embolus’ base present. Seminal reservoir not meandering, tibial apophysis long, single or bifurcate, sometimes with a ventral protrusion. First legs stout, 4th legs longer than 3rd ones. Description. Spiders below 3 mm long. Cephalothorax pear-shaped, widest at the fovea level, rather low, elongate, posterior thoracic slope starts at ⅔ of thorax’s length. Fovea well behind PLE, in the middle of cephalothorax. ClYpeus very narrow. Abdomen ovoid, spinnerets not distinctive. Chelicerae with single or two-cuspidate teeth on the posterior margin. First legs stout, with 3 and 2 pairs of ventrolateral spines on tibiae and metatarsi, respectively. Other legs rather delicate, not distinctive, legs 4 longer than legs 3. All legs, especially 2–4 with dark and light bands on particular segments. Palpal organ’s embolus large, cork-screw-like, sometimes with a small projection (p) at its base. Sperm duct (sd) not meandering, tegulum ovoid or with lobe (tl). Palpal tibial apophysis long, sometimes bifurcate, with or without additional protrusion. Females not known. Relationships and distribution. Due to the unique male genitalic structure, the taxonomic position of this enigmatic genus is unclear—at least as long as females are known. The particular species are recorded from single localities (Fig. 5), thus the predictions of their potential distribution are not possible at this stage.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
