Revision of the genus Pelecinobaccha Shannon, description of Relictanum gen. nov., and redescription of Atylobaccha flukiella (Curran, 1941) (Diptera: Syrphidae)
Bibliographic record
Abstract
Recent phylogenetic analyses of Ocyptamus Macquart, 1834 (Diptera, Syrphidae) confirmed the paraphyly of this genus and provided evidence to divide it into several monophyletic subgroups, of which the largest is the clade traditionally treated as the Ocyptamus tristis species group. This group is here redefined, divided into the genera Pelecinobaccha Shannon, 1927 and Relictanum gen. nov., and revised along with the closely related and newly resurrected genus Atylobaccha Hull, 1949. Twenty-four new species (22 in Pelecinobaccha and two in Relictanum) are described and 35 species (27 in Pelecinobaccha, seven in Relictanum and Atylobaccha flukiella Curran, 1941) are redescribed. Pelecinobaccha is divided into four species groups (P. adspersa species group, P. brevipennis species group, P. peruviana species group and P. susio species group). An identification key, illustrations and distribution maps for all species from this study are also presented.
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.

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.
