Re-validation of <i>Gonorhynchus adiscus</i> and <i>G. diplochilus</i> (Teleostei: Cyprinidae) using morphological and molecular data
Bibliographic record
Abstract
Small and silvery cyprinid species from eastern Iran which are usually known as Crossocheilus latius are reviewed based on morphological and molecular characters of the mtDNA COI barcode region. We demonstrate that fishes which had been identified as Crossocheilus Kuhl & van Hasselt, 1823 in Iran actually belong to the genus Gonorhynchus McClelland, 1838 with two species: G. adiscus (Annandale, 1919) and G. diplochilus (Heckel, 1838), which are rediagnosed here. Both species are well distinguished by gill raker counts, number of scales between anus and anal fin, barbel size and minimum body depth. G. adiscus and G. diplochilus are also distinguished by molecular characters of the mtDNA COI barcode region. Both species are phylogenetically close to Gonorhynchus latius (Hamilton, 1822) which is restricted to India, Nepal and Bangladesh and to G. burmanicus (Hora, 1936), restricted to India and Myanmar. All of these four related taxa are phylogenetically closer to the genus Garra than the genus Crossocheilus (restricted to south-east Asia).

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.
