Mizoram has recorded two new-to-science amphibian species, Duttaphrynus phawngpui and Ingerana aizawl. The two species were described in scientific publications dated 13 September 2026 and 14 September 2026, respectively.
Taxonomy of the Newly Described Species
Duttaphrynus phawngpui is a toad in the genus Duttaphrynus, which belongs to the family Bufonidae. Ingerana aizawl is a frog in the genus Ingerana, which belongs to the family Dicroglossidae.
Type Localities and Naming
Duttaphrynus phawngpui was found at elevations above 2,000 metres in Phawngpui National Park. The species name refers to Phawngpui, also called Blue Mountain, which is the highest peak in Mizoram. Ingerana aizawl was discovered along a stream on the Mizoram University campus, and its name refers to Aizawl, the capital of Mizoram.
Scientific Reassessment and Research Institutions
Ingerana aizawl had been identified as Ingerana borealis for more than two decades before taxonomic reassessment. The studies involved researchers from Mizoram University, Cotton University, Help Earth, and the National Research and Innovation Agency in Indonesia.

Amphibian Diversity in Northeast India
Northeast India is a recognised region for amphibian diversity, with many species linked to forested hills, streams, and high-altitude habitats. Isolated mountain tops in the region are often described in biogeography as “sky islands”, a term used for separated upland habitats with distinct species assemblages.
