A new genus and a new species in the tribe Eryciini (Diptera, Tachinidae) from Area de Conservación Guanacaste in north-western Costa Rica
Bibliographic record
Abstract
A new genus and species of within the tribe Eryciini are described from the Area de Conservación Guanacaste (ACG) in north-western Costa Rica. Specimens were reared from wild-caught caterpillars collected during an ongoing biodiversity inventory within the ACG. An integrative taxonomic approach was used to characterise the new taxa, incorporating morphological analysis, life history data and DNA barcodes, supported by high-resolution photographs. Furthermore, two new combinations are proposed and the associated species are re-described. A lectotype is designated for Exorista loxostegae (Reinhard, 1922) and an identification key to the species of the new genus is provided. The description of the new genus Santarosamyia Fleming and Wood, 2024 gen. nov. along with the new species: Santarosamyia woodorum Fleming & Wood sp. nov. are provided. The following new combinations are proposed: Nilea erecta (Coquillett, 1902) as Santarosamyia erecta (Coquillett, 1902) comb. nov. ; Nilea uniplilum (Aldrich & Webber, 1924) as Santarosamyia unipilum (Aldrich & Webber, 1924) comb. nov. A lectotype is designated for Exorista loxostegae (Reinhard, 1922). Tachinidae, Diptera, Costa Rica, CO1, Parasitoid, Guanacaste

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.
