A new diatom (Bacillariophyta) species—Fallacia cinariana sp. nov.—from Kaklık Cave in the Western Anatolian Karst Region, Republic of Türkiye
Bibliographic record
Abstract
A new Fallacia cinariana sp. nov. is described from a unique extreme microenvironment in the highly calcareous Kaklık Cave, Pamukkale Travertines in the Western Anatolian Karst Region, Türkiye with calcareous (pH 8.2) rich waters. Valves of F. cinariana are small (<15 um), linear to linear-elliptic with rounded ends. As with the type species for the genus (F. pygmaea (Kützing) Stickle & D.G.Mann), the axial area is composed of a narrow raphe sternum and valve face slits/occlusions on either side, 500–900 nm length. The striae are biseriate and form around a small round to elliptic central area. Falacia subhamulata Lange-Bertalot from Europe is considered the closest morphologically aligned species being larger, wider, broader central area, elliptic to round valve face slits/opening, and fewer biseriate striae. Other comparable taxa include Fallacia subhamulata (Grunow) D.G.Mann, F. angarae, Metzeltin, Kulikovskiy & Lange-Bertalot, F. helenensis (Schulz) D.G.Mann, F. lange-bertalotii Reichardt, F. lenzii Lange-Bertalot and F. pseudohelensis Kulikovskiy, Metzeltin & Lange-Bertalot. Among them, Fallacia lange-bertalotii (originally described from the Europe) co-occurs in Kaklik Cave and is similar, but F. cinariana has different morphological characters and distinct valve face slits/occlusions.

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.
