The milliped family Pyrgodesmidae in the continental USA, with the first record of<i>Poratia digitata</i>(Porat) from the Bahamas (Diplopoda: Polydesmida)
Bibliographic record
Abstract
The milliped family Pyrgodesmidae in the continental USA comprises eight species: Poratia digitata (Porat), P. obliterata (Kraus), Calpytodesmus sanctus Schubart, Psochodesmus crescentis Cook, Myrmecodesmus formicarius Silvestri, Myrmecodesmus digitatus (Loomis), Myrmecodesmus reddelli new species and ‘Lophodesmus’ bituberculatus Loomis, previously known only from Puerto Rico. They inhabit urban and native environments and caves from northern coastal Georgia and north-central Alabama to south Florida and central and southern Texas, and have been encountered in greenhouses in Illinois. Four species represent human importations, probably from the Neotropics, but the other four appear to be indigenous, and possibly endemic, to certain areas. The occurrence of M. formicarius in south-eastern Louisiana is considered an introduction, but that in Texas is logically the northern part of its natural distribution, which extends southward to Veracruz, Mexico. Likewise, M. digitatus is endemic to the Gulf Coastal states from the eastern panhandle of Florida to western and northern Louisiana, and P. crescentis may be endemic to peninsular Florida. Myrmecodesmus reddelli is known only from the type locality in Kendall County, Texas, and may also be a Mexican form that extends northward into this state. Poratia digitata is recorded for the first time from the Bahamas (Andros Island), Louisiana, and Texas, and M. digitatus and ‘L.’ bituberculatus are newly recorded from Alabama and Florida, respectively; Ilyma colotlipa Chamberlin is placed in synonymy under M. formicarius. A key and illustrations of pertinent somatic features facilitate determinations.

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.
