A new species of the genus Megophrys Gunther, 1864 (Amphibia: Anura: Megophryidae) from Mount Wuyi, China
Bibliographic record
Abstract
A new species of horned toad, Megophrys ombrophila sp. nov., is described based on specimens found from Guadun village from Mount Wuyi in northwestern Fujian Province, China. The species is distinguished from other described Megophrys by morphology, bioacoustics, and molecular data of the 12S and 16S mitochondrial loci. The species is characterized by its rotund stature, head length approximately equal to head width, canthus rostralis well developed, tympanum large and distinct, vomerine teeth absent, margin of tongue smooth, not notched from behind, heels of the feet not meeting when femurs are held at 90° to the axis of the body and tibias are depressed against the femur, toes weakly webbed at base, dorsal skin mostly smooth with scattered granules and ridges, usually the presence of two discontinuous dorsolateral ridges, supratympanic fold distinct and well-developed, and with females ranging from 32.8-35 mm snout-to-vent length, and males ranging from 27.4-34.5 mm SVL. In its type locality, the species is sympatric with M. boettgeri and M. kuatunensis; and phylogenetically, the most closely related described species is M. obesa from southwest Guangdong province. As more cryptic species are described within the subfamily Megophryinae, the more apparent becomes the need for fine-scale molecular and phenotypic assessment to capture the many forms of this hyper-diverse group.
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.
