Key to Families of Chalcidoidea
Bibliographic record
Abstract
The logical basis of identification keys and the principles underlying character selection are briefly discussed. The key is dichotomous in form and is intended to identify all known Chalcidoidea species to family, or in some cases to a lower level incertae sedis taxon. A set of shortcuts is provided to direct users to major branch points in the key. The key itself is composed of 116 couplets, divided into 11 sections: Part 1: Divergent and early-branching groups; Part 2: Most taxa with 4 or fewer tarsomeres; Part 3: Species with 5 tarsomeres (at least in fore and hind legs); Part 3.1: Acropleuron expanded; Part 3.2: Metafemur with ventral teeth; Part 3.3: Antenna with 8 or fewer flagellomeres; Part 3.4: Eyes ventrally divergent; Part 3.5: Antenna with 10 or fewer flagellomeres; Part 3.6: Generalized taxa with 11 or 12 flagellomeres in some members; Part 3.6.1: Occipital carina always present; and Part 3.6.2: Occipital carina either absent or present. Each couplet is illustrated with figure embedded directly in the body of the key.
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.
How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
