Revision of the Mesoamerican species of Calolydella Townsend (Diptera: Tachinidae) and description of twenty-three new species reared from caterpillars in Area de Conservación Guanacaste, northwestern Costa Rica
Bibliographic record
Abstract
Twenty-three new species of the genus Calolydella Townsend, 1927 (Diptera: Tachinidae) are described, all reared from multiple species of wild-caught caterpillars across a wide variety of families (Lepidoptera: Crambidae; Erebidae; Geometridae; Hesperiidae; Lycaenidae; Nymphalidae; Pieridae; Riodinidae; and Sphingidae). All caterpillars were collected within Area de Conservación Guanacaste (ACG), in northwestern Costa Rica. This study provides a concise description of each new species using morphology, life history, molecular data, and photographic documentation. In addition to the new species, we also provide a generic redescription and revised key to species of the genus Calolydella from Central and South America. The following 23 new species of Calolydella are described by Fleming and Wood: C. adelinamoralesae sp. n., C. alexanderjamesi sp. n., C. argentea sp. n., C. aureofacies sp. n., C. bicolor sp. n., C. bifissus sp. n., C. crocata sp. n., C. destituta sp. n., C. discalis sp. n., C. erasmocoronadoi sp. n., C. felipechavarriai sp. n., C. fredriksjobergi sp. n., C. inflatipalpis sp. n., C. interrupta sp. n., C. nigripalpis sp. n., C. omissa sp. n., C. ordinalis sp. n., C. renemalaisei sp. n., C. susanaroibasae sp. n., C. tanyadapkeyae sp. n., C. tenebrosa sp. n., C. timjamesi sp. n., C. virginiajamesae sp. n. Lydella frugale Curran, 1934 is proposed as a new synonym of Pygophorinia peruviana Townsend, 1927, syn. n., under the combination Calolydella frugale (Curran, 1934), comb. n.

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.
