Foot posteriorly bifurcated, cephalic shield with tentacular lobes. Rachidian tooth denticulate, lateral teeth with minute denticulation, teeth on left side slightly smaller than on the right. Gizzard with no plates. Short elongate penial sheath dividing into prostate with two coiled branches, thick branch with blunt ending, thin branch with bulky lump at the end. Type locality. Loch Torridon, Scotland. Material examined. Gullmarn, Sweden, 5 spcs (dissected), ZMUC unnumbered, H = 2–3.3 mm. 60°19'45.0120" N, 005°15'01.8" E, Bergen, Knappen, Norway, 1 spc (dissected), ZMBN 90597, H = 2.6 mm. Shell (Fig. 7 A–D): Maximum H = 5.8 mm (Schiøtte 1998). External, thin; white to transparent; globoseelongate in shape, tapering in straight line posteriorly from widest point in middle of shell, anterior part rounded, aperture wide with parietal callus, apex truncate, protoconch protruding, umbilicate; shell surface smooth, faint growth lines. Animal: Body white. Foot posteriorly bifurcated. Cephalic shield with tentacular lobes posteriorly. Radula (Fig. 7 E): Radular formula 12 x 1.1.1. Rachidian tooth with two coarsely denticulate lobes. Lateral teeth long, inner edge denticulate. Radula slightly asymmetrical with left laterals smaller than the right laterals, no large denticle on tip of left laterals. Male reproductive system (Fig. 7 F): Short elongate penial sheath dividing into prostate with two coiled branches, thick branch with blunt ending, thin branch with bulky lump at the end. Ecology. This species can be found from the intertidal down to 350 m (Thompson 1988; Poppe & Goto 1991). Specimens examined by Schiøtte (1998) were found in tide pools, on mire, pebbles, mud, sand, clay, shell gravel, algae and stones with Corallina. Distribution. Circumpolar from New England, the Canadian Archipelago, over Greenland, Iceland, the Barents Sea, White Sea, Kara Sea, Laptev Sea to the east Siberian Seas, down to Japan, British Columbia (Schiøtte 1998; Kantor & Sysoev 2006). In Norway along the entire coastline; British Isles southwards to the Mediterranean Sea and the Canary Islands (Thompson 1988; Poppe & Goto 1991; Schiøtte 1998; Høisaeter et al. 2001; Sneli et al. 2005). Remarks. Diaphana minuta was re-described recently and its taxonomic status discussed thoroughly (Schiøtte 1998). Before the latter revisionary work the species was surrounded by much taxonomic uncertainty. G. O. Sars (1878) recognized four species of Diaphana but mixed them up as he illustrated D. minuta (as D. hyalina and D. expansa) having an asymmetrical radula. Lemche (1948) synonymised most northern European species of Diaphana (D. globosa, D. hiemalis, D. glacialis, D. minuta) under the name D. minuta. However, these species show considerable differences in shells, radulae and male reproductive system as well as in ecological preferences and distributions (Schiøtte 1998). Thompson (1988) included three species, but only one (D. minuta) is identified correctly.

Not 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.
