THE FAUNAL AND SEASONAL COMPOSITION OF THE COMMUNITY OF APIONINAE (COLEOPTERA: BRENTIDAE) IN THE TROPICAL RAINFOREST OF THE SIERRA EL MADRIGAL IN STATE OF TABASCO, MEXICO
Bibliographic record
Abstract
Apioninae (Coleoptera: Brentidae) are beetles commonly known as seed or clover weevils, and all species are phytophagous and important in natural ecosystems. The main objective of this study was to record the faunal and seasonal composition of the Apioninae community in the tropical rainforest of Tabasco, Mexico. Sampling was carried out in 12 sites of the ecosystem during an annual cycle (January-December, 2021), using the method of beating the vegetation with an entomological net. We collected 1,191 specimens belonging to 33 species and nine genera. Apion panamense Sharp, Coelocephalapion accentor (Kissinger), C. iteratum (Kissinger) and Neapion cretaceicolle (Sharp) are new records for Tabasco. The genus Trichapion (Wagner) was the most species-rich. Apionion sp2 was the most abundant species. The highest richness, abundance and diversity (0D, 1D and 2D) were recorded during the dry season. Fourteen species showed marked seasonality, of which 12 species were recorded only in the dry season and two in the north. Fluctuations in richness and abundance showed its maximum peak in April, the month with the lowest rainfall. Shaded sites had the highest richness (32 species) and abundance (861 individuals). This study contributes to the knowledge of Apioninae by providing new ecological information on the subfamily. However, further studies of these beetles are needed to determine their geographic distribution and systematics.

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.
