Protaspa verrucosa Cavalier-Smith 2011
Bibliographic record
Abstract
Protaspa verrucosa (Larsen et Patterson, 1990) Cavalier-Smith, 2011 Fig. 5a Description: Cell outline is oval to roundish. Cells are 15–22 µm long and dorso-ventrally flattened. Cell surface is warty. The cells have a prominent ventral groove or slit, which extends from the subapical end almost to the posterior end of the cell. Two flagella emerge from the widely opened anterior depression. The anterior flagellum is about the cell length and beats from side to side. The posterior flagellum is about 1.3 times the cell length and trails. The nucleus is situated anteriorly below the flagellar insertion with anterior caps, which are not distinctive. Several materials are seen in the posterior part of the cell. The cells glide slowly. Rarely observed. Remarks: Generally the description here is accordance with the original description of Larsen and Patterson (1990). This species has been found at marine sites in Australia, Arctic Canada, Denmark, England, Gulf of Finland, Fiji and White Sea (Larsen and Patterson 1990; Tong et al. 1998; Vørs 1992a, b, 1993a; Tikhonenkov et al. 2006) and reported cell length is from 9 to 18 µm. It was quite common at Avoca Beach and co-occurred with Protaspa gemmifera Larsen et Patterson, 1990. This species is distinguished from other species in Protaspa by the strongly developed ventral groove and wide flagellar pocket. Protaspa verrucosa is very similar to Thaumatomastix setifera Lauterborn, 1896, T. tripus (Takahashi et Hara, 1984) Beech et Moestrup, 1986 and T. splendida Thomsen et al., 1995, but is distinguished by the lack of the visible body scales and spines.

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.
