New ‘Music Frog’ Species Discovered in Arunachal Pradesh

November 23, 2023

In a groundbreaking discovery, scientists have identified a new species of ‘music frog’ in the lush landscapes of Arunachal Pradesh. This finding, based on comprehensive analysis involving morphological, molecular, and acoustic evidence, sheds light on a previously unrecognized member of the Nidirana genus.

Distinct Features of the Noa-Dihing Music Frog

The scientists, Bitupan Boruah, V Deepak, and Abhijit Das, detailed their findings in an article published in the November 15 edition of the journal Zootaxa. The newly discovered frog, scientifically known as Nidirana noadihing, exhibits distinct phenotypic characteristics that set it apart from its congeners.

Morphological Traits: The Noa-Dihing Music Frog boasts a ‘robust’ body, with males measuring approximately 1.8 to 2.3 inches and females ranging from about 2.4 to 2.6 inches. Their ’rounded’ snouts and ‘smooth’ skin, adorned with bony protrusions on their backs, contribute to their unique appearance.
Coloration: These amphibians showcase a striking color palette, featuring a ‘pale cream’ line bordered with dark brown along the center of their bodies. Light brown limbs, adorned with dark stripes, further enhance their visual distinctiveness.
Habitat: The frogs were discovered nestled within vegetation in shallow pools of water, with male frogs emitting loud calls. Additional specimens were found in nearby marshy areas, the edges of a newly constructed pond, and along the side of a nearby road.

Naming the Species: A Tribute to the Noa-Dihing River

The new species received its name, Nidirana noadihing, as a homage to the Noa-Dihing River, the vicinity where these unique specimens were encountered and collected during field surveys conducted between August and September of the previous year.

Significance of the Discovery

This discovery marks the first confirmation of the Nidirana genus’s presence in India, expanding its known habitat beyond regions in Japan, Taiwan, China, Vietnam, Laos, and Thailand. The researchers stress the importance of exploring specialized habitats like marshlands, often overlooked, in uncovering new species.

Unique Vocalization and Other Characteristics

Noa-Dihing Music Frogs are distinguished not only by their size but also by their oval toe tips, the tubercles on their backs, and a distinctive call. The irregularly shaped and sized spots on their eyelids, along with dark stripes around their moderately large eyes, contribute to their unique visual features.

Conservation Implications

The discovery underscores the significance of continued exploration and conservation efforts in specialized habitats. The researchers emphasize the importance of marshlands and similar environments in unveiling the rich biodiversity that may be hidden within these often-neglected ecosystems.
