Adult and larval associations of the alpine stonefly genus Riekoperla McLellan (Plecoptera : Gripopterygidae) using mitochondrial DNA
Bibliographic record
Abstract
The current taxonomic understanding of the genus Riekoperla McLellan, 1971 (Gripopterygidae) is poor, with 15 of the 28 species and subspecies having unknown or uncertain larval associations. Sequences of a 657 bp fragment from the mitochondrial gene cytochrome c oxidase subunit 1 (CO1) were obtained from 122 specimens of 13 species collected throughout the alpine areas of New South Wales and Victoria, Australia. Of these, sequence data associated adults and larvae for the following 10 species: R. alpina McLellan, 1971, R. cf. intermedia, R. compressa Theischinger, 1985, R. hynesorum Theischinger, 1985, R. karki McLellan, 1971, R. montana Theischinger, 1985, R. reticulata (Kimmins, 1951), R. rugosa (Kimmins, 1951), R. trapeza Theischinger, 1985, and R. tuberculata McLellan, 1971. Adults of R. intermedia Theischinger, 1985, R. triloba triloba McLellan, 1971 and R. williamsi McLellan, 1971 were sequenced but no larvae were associated with them. The 13 species were reciprocally monophyletic and had minimum interspecific sequence divergences ranging from 7.2–19.5%, higher than the maximum intraspecific sequence divergences (0.6–5.8%). The combination of morphology and molecular data enabled rapid life stage association for alpine Riekoperla species and this method should be used more frequently for other environmentally significant aquatic insects.
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.

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.
