Bibliographic record
Abstract
CERATOPERA PILIFERA KARLING, 1986 (FIG. 4B, E, F) Ceratopera pilifera Karling, 1986: 212–214, figs 58, 65–67. New localities: Clover Point, Victoria, British Columbia, Canada (48°24 ′ 12 ″ N, 123°21 ′ 03 ″ W), algae in rocky lower intertidal (14/11/2016). Little Wolf Beach, Calvert Island, British Columbia, Canada (51°39 ′ 53 ″ N, 128°07 ′ 44 ″ W), algae in rocky lower intertidal (07/04/2016). Friday Harbor, San Juan Island, Washington, USA (48°32 ′ 42 ″ N, 123°00 ′ 44 ″ W), algae on the dock of the marine station (08/10/2016). Known distribution: Northeast Pacific Ocean: Oregon (Karling, 1986). Material: Observations on five live animals. Three whole mounts (BBM MI4046 – MI4048). 18S rRNA (G e n B a n k a c c e s s i o n # M F 3 2 1 7 4 9), 2 8S r R N A (GenBank accession # MF321759). Remarks: Animals are 0.7– 1 mm long and appear plumper and more Proxenetes- shaped than described by Karling (1986) (Fig. 4B). Internal organization typical for species of Ceratopera with paired lenticular eyes, rostral rhabdite tracks, a pharynx located mid-body, paired testes situated behind the pharynx, paired ovaries and vitellaria. Two large ovate seminal vesicles are connected to the rounded copulatory bulb. The stylet is 97–106 μ m long (x = 100 μ m, n = 3; non-axial: 52–57 μ m) and resembles the stylet of C. pilifera as described by Karling (1986). It consists of a curved stylet proper, measuring 74–80 μ m (x = 76 μ m, n = 3), with a 23- to 26- μ m-long (x = 24 μ m, n = 3) proximal base, and a curved, funnel-shaped, 46- to 47- μ m-long (x = 46 μ m, n = 3) accessory mantle piece (Fig. 4F). These measurements correspond to the ones from the Oregonian specimens. The hair-like eponymous protrusion of the accessory mantle piece could not be observed in our specimens. However, a thickened part of the convex edge of the mantle piece (arrow in Fig. 4F) corresponds to this structure. Moreover, the needle-like structure on the accessory piece in figure 67 in Karling (1986) could easily be interpreted as a thickened edge rather than a hair-like protrusion. The funnel-shaped and distally curled bursal appendage measures 78–88 μ m (x = 82 μ m; n = 3) and is typical for species of Ceratopera sensu Den Hartog. Distally it splits into two 29- to 32- μ m-long tubes (x = 31 μ m; n = 3). Based on the strong resemblance of the stylet and bursal appendage with those of C. pilifera, we attribute our specimens to this species.

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.
