Phylogenetics and molecular identification of the<i>Ochlerotatus communis</i>complex (Diptera: Culicidae) using DNA barcoding and polymerase chain reaction-restriction fragment length polymorphism
Bibliographic record
Abstract
Abstract The Ochlerotatus communis (De Geer, 1776) complex consists of four cryptic mosquito species in North America, including: O. communis , Ochlerotatus churchillensis (Ellis and Brust, 1973), Ochlerotatus nevadensis (Chapman and Barr, 1964), and Ochlerotatus tahoensis (Dyar, 1916). Most of the morphological characters used for the identification of these species are quantitative and overlap across species. Here we evaluated the efficacy of DNA barcoding for identification of three members of the communis complex ( O. nevadensis is not included in this study) and developed diagnostic restriction fragment length polymorphism (RFLP) patterns for O. communis and O. churchillensis . A phylogeny of 23 Ochlerotatus Lynch Arribálzaga, 1891 species was inferred using mitochondrial cytochrome c oxidase subunit I gene sequences. All species included in our analysis within the O. communis complex were delineated using cytochrome c oxidase subunit I barcodes. However, this complex was recovered as paraphyletic with respect to Ochlerotatus abserratus (Felt and Young, 1904) and Ochlerotatus implicatus (Vockeroth, 1954), indicating the need for increased genetic and taxonomic sampling to infer the phylogenetic relationships of these taxa. The RFLP profile for multiple field specimens of O. communis was distinct from all RFLP patterns for O. churchillensis , and this method can be used as an efficient molecular method for the identification these species.

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.
