Abstract
In this paper we call attention to the identity of the type species of Thiodina Simon, 1900, T. nicoleti Roewer, 1951. When Simon proposed the genus, he characterized it based on morphological features found in species he described, but not found in the type species he designated, and whose type specimens, apparently, he had not examined. Nicolet's original description makes it clear that the type species is not closely related to the more familiar species placed in the genus. This misinterpretation was followed by contemporary researchers and survives until today. Here we designate and describe a neotype for T. nicoleti. We revalidate Colonus F.O.P.-Cambridge, 1901 and Nilakantha Peckham & Peckham, 1901 to transfer most species formerly placed in Thiodina. The combinations Colonus puerperus (Hentz, 1846), Nilakantha cockerelli Peckham & Peckham, 1901 and N. peckhami Bryant, 1940 are restored. The following new combinations are established: Colonus branicki (Taczanowski, 1871) new comb., C. candidus (Mello-Leitão, 1922) new comb., C. germaini (Simon, 1900) new comb., C. hesperus (Richman & Vetter, 2004) new comb., C. melanogaster (Mello-Leitão, 1917) new comb., C. pallidus (C.L. Koch, 1846) new comb., C. pseustes (Chamberlin & Ivie, 1936) new comb., C. punctulatus (Mello-Leitão, 1917) new comb., C. rishwani (Makhan, 2006) new comb., C. robustus (Mello-Leitão, 1945) new comb., C. sylvanus (Hentz, 1846) new comb., C. vaccula (Simon, 1900) new comb., C. vellardi (Soares & Camargo, 1948) new comb., Nilakantha beugelorum (Wolff, 1990) new comb., N. crucifera (F.O.P.-Cambridge, 1901) new comb., and N. inerma (Bryant, 1940) new comb. Thiodina setosa Mello-Leitão, 1947 is tentatively transferred to Cotinusa Simon, 1900.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
