Phylogeny of the high-altitude tarantulas Hapalotremus Simon, 1903 (Araneae: Mygalomorphae: Theraphosidae) with the description of a new species
Bibliographic record
Abstract
Abstract A cladistics analysis of the high-altitude tarantulas of the genus Hapalotremus was carried out for the first time with a matrix of 21 taxa and 69 morphological characters using both equal and implied weights. Two consistent topologies were obtained with a concavity = 10.541, resulting from a sensitivity analysis. Both cladograms suggest Hapalotremus as monophyletic. Hapalotremus synapomorphies are females with spermathecae consisting in a single oval receptacle and tibia of the first pair of legs of males very short. Hapalotremus is composed of 15 species including a new species: Hapalotremus munaycha sp. nov. This new species was found to be the sister species of H. vilcanota and is distributed in central Peru at elevations about 4000 m.a.s.l. on interandean valleys. The new species distinguishes from the other known species of the genus by the intense white color on legs, carapace and cheliceae, together with a male palpal bulb carrying a slightly developed prolateral superior keel and the subapical keel ending with two very small teeth. Also, females of Hapalotremus munaycha sp. nov. are characterized by the spermathecae with very wide basal portion and small apical projections pointing upwards.

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.
