A Contribution to the Taxonomy of the Cleptoparasitic Bee Subgenus<i>Cyrtocoelioxys</i>Mitchell of<i>Coelioxys</i>Latreille (Hymenoptera: Megachilidae)
Bibliographic record
Abstract
Three new species belonging to the subgenus Cyrtocoelioxys Mitchell, 1973 of Coelioxys Latreille, 1809, Coelioxys (Cyrtocoelioxys) lactea sp. nov. from São Paulo State, Brazil and C. (C.) acanthosara sp. nov., and C. (C.) jordiana sp. nov. both from Nayarit and Oaxaca States, Mexico, are described and illustrated. An updated checklist of the 73 species of the subgenus Cyrtocoelioxys of Coelioxys is also provided. Two species are placed in synonymy: Coelioxys (C.) sanguinea Friese, 1921 syn. nov. of Coelioxys (C.) costaricensis Cockerell, 1914 (nec Friese, 1916) and Coelioxys (C.) gigantea Friese, 1921 syn. nov. of Coelioxys (C.) zonula Smith, 1854. The subspecies Coelioxys (C.) unidentata obscuriventris Friese, 1921 is raised to species level, as C. (C.) obscuriventris stat. nov. For the following three species the new subgeneric placement is proposed: C. (C.) ignava Smith, 1879 = C. (Glyptocoelioxys) ignava; C. (G.) leopoldensis Friese, 1921 = C. (Cyrtocoelioxys) leopoldensis and C. (G.) triangula Friese, 1906 = C. (C.) triangula. Five species previously considered as incertae sedis are assigned to Coelioxys (Cyrtocoelioxys): C. (C.) ambrosettii Holmberg, 1918; C. (C.) hirtiventris Popov, 1946; C. (C.) paranensis Schrottky, 1920; C. (C.) spatulata Friese, 1921 and C. (C.) tabayensis Schrottky, 1920. A key to the Mexican species of the subgenus Cyrtocoelioxys is provided.
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.
