Annotated checklist and new records of Harpacticoida (Copepoda) from a coastal system of northern Colombia, South America
Bibliographic record
Abstract
The harpacticoid copepod fauna of the Laguna Navío Quebrado, La Guajira, a protected area of the northern Colombian coast, was studied from plankton samples obtained at littoral areas covered by vegetation (macrophytes and mangroves), and at limnetic habitats close to an oyster bank. A total of 14 species of harpacticoid copepods are reported from the surveyed area. Nine of these species are new to the Colombian copepod fauna:Schizopera knabeniLang, 1965,Cletocamptus helobiusFleeger, 1980,Quinquelaophonte quinquespinosa(Sewell, 1924),Sarsamphiascus hirtus(Gurney, 1927),Parategastes herteliJacobi, 1953,Enhydrosoma lacunaeJakubisiak, 1933,Metis holothuriae(Edwards, 1891),Robertsonia propinqua(T. Scott, 1894) andNitokra tayloriGómez, Carrasco & Morales-Serna, 2012. The first two species have not been hitherto recorded from South America and the last one is reported for the Americas for the first time. Nine of these species are also new records for the Caribbean Sea. This is the first report on the marine benthic harpacticoid Copepoda from northern Colombia. A complete species list plus brief diagnostic descriptions of the new records for the Colombian harpacticoid copepod fauna are provided together with morphologic remarks, notes on the variability of some species and their distribution.
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.
