Abstract

fetched live from OpenAlex

cf. Helopelopia pilicaudata (Walley) (Fig. 5 A–D) Material examined. CANADA: Manitoba, Lake Winnipeg: South Basin, 1 larva, 3.–12. x.1969; Narrows, 1 larva, 9.–17. vii. 1969; North Basin, 5 larvae 9.–17. vii., 1969. These larvae may belong to Helopelopia according to Epler (2001, couplet 36). Fourth instar larva (n = 1–3) Total length 6.12–11.33 mm. Head capsule length 0.99–1.08 mm. Head. Apex of antenna as in Fig. 5 A. Lengths of antennal segments (in µm): 415–440, 73–81, 7–9, 3–4, 2. AR 4.44–4.66. Basal antennal segment 30–35 µm wide, ring organ 0.67–0.70 from base, blade 76–86 µm. Style at apex of second segment 12 µm long. Apex of labrum as in Fig. 5 B. Mandible 210–244 µm long. Basal segment of maxillary palp (Fig. 5 C) 72–90 µm long, 14–22 µm wide, 3.91–5.14 times as long as wide. Ligula (Fig. 5 D) 114–128 µm long. Paraglossa (Fig. 5 D) 46–48 µm long. Abdomen. Body with long hairs 0.8–1.0 times as long as width of segments. Procercus 156–170 µm long, 50– 53 µm wide, 2.94–3.20 times as long as wide. Anal setae 920 µm, supraanal seta 620 µm, supraanal seta/anal setae 0.67. Anal tubules 290–340 µm long. Posterior parapods 689–810 µm long, with 3–4 very slightly darker claws. Third instar larva (n = 3) Total length 4.61–6.11 mm. Head capsule length 0.64 mm. Head. Lengths of antennal segments (in µm): 230–238, 46–48, 7–8, 2–3, 1. AR 3.90–4.30. Mandible 134–138 µm long. Abdomen. Procercus 90–106 µm long, 34–38 µm wide, 2.37–3.06 times as long as wide. Remarks. The larvae of Helopelopia Roback are larger than larvae of Conchapelopia Fittkau (Roback 1981: 100, Epler 2001 couplet 36). The present specimens are larger than mentioned by Roback (1981) for H. cornuticadata (Walley) and since H. pilicaudata is present in Lake Winnipeg likely belong to that species or species complex.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
