A new horned toad of Boulenophrys (Anura, Megophryidae) was discovered in Hubei Province, China

The diversity of the genus Boulenophrys, with around 72 species identified so far, is still thought to be highly underestimated, as it contains a large number of undescribed cryptic species. The favorable ecological environment of the Dalaoling National Nature Reserve, located in Yichang City, Hubei Province, is home to many characteristic species. This work describes a new species from central China, namely: Boulenophrys dalaolingensis Wang, Chen & Liu, 2025, sp. nov.

Morphologically, the new species is characterized by the combination of nine external characters: (1) medium-sized body (SVL 49.9–56.2 mm in seven males, SVL 50.3–60.0 mm in three females; (2) vomerine teeth absent; (3) margin of tongue smooth, with weakly notch behind; (4) relative finger length III> II = I> IV; (5) tibio-tarsal articulation of adpressed limb reaching posterior corner of the eye; and (6) toes with more than 1 / 4 web.

Molecularly, the new species forms an independent clade with strong support in the phylogenetic trees of the genus based on two partial mitochondrial sequences: 16 S ribosomal RNA (16 S rRNA) and cytochrome c oxidase subunit I (COI). Morphological and molecular phylogenetic analyses suggest that it is a new species that has not been systematically described. Our work increases the number of species in the genus Boulenophrys to 73.
