A contribution on the milliped tribe Nannariini (Polydesmida: Xystodesmidae): Revalidation of Mimuloria Chamberlin 1928; identities of Fontaria oblonga C. L. Koch 1847, and Nannaria minor Chamberlin 1918; elucidation of the tribal range; and commentaries
Bibliographic record
Abstract
Mimuloria Chamberlin 1928 is revived from synonymy under Nannaria Chamberlin 1918a for Nannariini (Polydesmida: Xystodesmidae) with simple but apically ornamented gonopodal acropodites that arch or lean mediad and cross body midlines and opposing acropodites in situ. It encompasses two assemblages based primarily on the nature of the ornamentations, the castanea and dilatata species groups. The former includes three established species [M. castanea (McNeill 1887) M. missouriensis Chamberlin 1928 and M. davidcauseyi (Causey 1950a)], and the latter contains two new ones (M. dilatata [M. d. dilatata, M. d. sigmoidea], and M. rhysodesmoides). Castanaria Causey 1950b is returned to synonymy under Mimuloria, and C. depalmai Causey 1950b is placed under M. castanea, thereby constituting a new synonymy. The fi rst illustrations of the holotype gonopods of Fontaria oblonga C. L. Koch 1847 and N. minor Chamberlin 1918a unequivocally establish their identities, and the convoluted nomenclatural tangle involving Oenomaea Hoffman 1964 and O. pulchella (Bollman 1889a) is detailed. Whether in Oenomaea or a new genus, separate generic status seems appropriate for Nannariini with subterminal solenomeres; N. morrisoni Hoffman 1948 and its potential synonym N. shenandoa Hoffman 1949 may also belong here. Initial tribal localities are reported from Alabama, South Carolina, and coastal Virginia and Maryland, and “O. pulchella” occurs in northern Alabama north/west of the Tennessee River; M. castanea is newly recorded from Missouri and Tennessee. A horizontally subtriangular distribution in the eastern and midwestern states is projected for Nannariini, which even occur on South Bass Island, Ohio, in Lake Erie, and may thus inhabit nearby Pelee Island, Ontario, Canada.

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.
