Mites of the genus<i>Harpyrhynchiella</i>Fain, 1972 (Acariformes: Harpirhynchidae), an example of an unusual mating strategy
Bibliographic record
Abstract
The genus Cypsharpirhynchus Fain, 1995 (Acariformes: Harpirhynchidae: Harpirhynchinae) is lowered in the rank to the subgenus of the genus Harpyrhynchiella Fain, 1972 based on the examination of the external morphology in both sexes. The revised diagnoses of the genus Harpirhynchiella and its subgenera are provided. A new species, Harpyrhynchiella (Cypsharpirhynchus) apus sp. nov., is described from both sexes ex Apus apus (Linnaeus, 1758) (Apodiformes: Apodidae) in the northwest of Russia. Females of the new species differ from Harpyrhynchiella (Cypsharpirhynchus) cypsiuri Fain, 1972 by the longer body (380–400) (versus 285–320 in H. cypsiuri), the presence of the accessory dorsal shields (versus absence) and by the lateral tuberculate areas that do not reach close to the lateral margins of the idiosoma (versus reaching). Notes on mating strategy of these mites are provided. Some larvae (designated female larvae) of Harpyrhynchiella apus have an internal, globular, sclerotized structure presumed to be a spermatheca, while others (designated male larvae) lack this structure. This is the first record of such sexual dimorphism in larvae of Harpirhynchidae. In Harpyrhynchiella spp., almost immobile female nymphs and adult females live individually in intracutaneous layers; females remain within the nymphal skin and oviposit there. This life history suggests that mating takes place on the skin between adult males and female larvae. The inseminated larva burrows into the host skin and moults there into the immobile female nymph or the female larva moults on the host skin surface and the weakly mobile nymph burrows into the skin.http://zoobank.org/urn:lsid:zoobank.org:pub:5FB52745-0342-4197-B36A-15FB4078D04F

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.
