Abstract

fetched live from OpenAlex

Cheilosia (Cheilosia) melanopa (Zetterstedt, 1843) Fig. 46 Eristalis melanopa Zetterstedt, 1843: 807. Cheilosia melanopa – Barkalov 1993: 714. — Mengual et al. 2020: 18 (part, see Remarks in C. redi). Differential diagnosis Given the pilose face and eye, almost entirely black legs and in the male a sickle-shaped dorsal lobe of the postgonite, C. melanopa is easily confused with C. borjomi sp. nov., C. lasiopa, C. redi and C. variabilis (see Francuski et al. 2009 for drawings of the male genitalia of these species). It differs from C. lasiopa by longer setae on posterior margin of scutellum and the male by shorter sickle-shaped dorsal lobe of postgonite. Similar to C. borjomi and C. variabilis but on average with smaller body size (8–10 mm vs 10–12 mm), stockier abdomen, tibiae usually narrowly yellow at base (usually all black in C. borjomi and C. variabilis), and in the male by the absence of black setae on ventral part of metafemur (present in males C. borjomi and C. variabilis). Females of C. melanopa have the posterior anepisternum pruinose (shiny in those of C. variabilis) and scutum with short erect predominantly yellow pile and with longer erect sparse black pile intermixed (with short semi-adpressed pile, this pile usually predominantly black and with longer erect sparse black pile intermixed in C. borjomi). Very similar to C. redi; see Differential diagnosis of that species. Material examined Collected in 2018, 2019 and 2021; see Mengual et al. (2020) for detailed records from 2018. Genetics COI sequences of C. melanopa from the Caucasus and other Palaearctic locations group together in our NJ tree with high support (BS = 98.1%). Biology During our expeditions, collected between 10 June and 31 July at an altitude on alpine meadows between 1900 and 2887 m a.s.l. Distribution Holarctic, including the Caucasus (Armenia, Georgia, Northern Caucasus).

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.
