A new fanged frog of the genus Limnonectes Fitzinger, 1843 (Anura: Dicroglossidae) from Langbian Plateau, southern Vietnam
Bibliographic record
Abstract
We describe a new frog of the genus Limnonectes from the Langbian Plateau in southern Vietnam based on morphological and molecular analyses. Limnonectes splendissimus sp. nov. shares morphological characteristics similar to L. poilani from central Vietnam yet is distinguishable from its congeners based on the following combination of diagnostic characters: large body-size (SVL 104.1-107.0 mm in three adult males, 87.2-97.7 mm in two adult females); head length longer than wide (HW/HL = 0.91±0.01 in adult males, 0.87±0.08 in adult females); adult males having an enlarged head height and a nuptial pad on finger I; eye diameter about three-fifths of tympanum-eye distance in adult males (ED/TED = 0.62±0.13) and longer than tympanum-eye distance in adult females (ED/TED = 1.40±0.02); distinct tympanum; presence of vomerine teeth; a tendency for a more prominent odontoid height (OH 8.0 ± 0.6 mm in adult males, 4.5±0.9 mm in adult females); throat surface in juveniles very distinct with black and white pattern that covers both the throat and anterior half of venter, and latter half of venter yellow. Phylogenetic analyses place the new species as the sister species of L. poilani. The new species differs from its congeners by an uncorrected p-distances in 16S sequences ranging from 8.2% (vs. L. poilani) to 14.6% (vs. L. dabanus).
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.
