A brand new-to-science cryptic amphibian has given violence-hit Manipur one thing to cheer about amid bloodshed and gloom.
A crew of scientists trekked to the Khongtheng mountain vary in 2022 to uncover the mysteries of the Tylototriton verrucosus, generally referred to as crocodile newt, whose members had lengthy confused even probably the most skilled of herpetologists.
They ended up recording a brand new species of salamander — the Tylototriton zaimeng — within the Zaimeng Lake inside the Koubru Forest Division in Kangpokpi district, one of many worst-hit by the ethnic violence that has scarred Manipur since May 3.
Zaimeng within the Liangmai Naga dialect means “puzzle” or “mystery”.
The research on the brand new salamander has been revealed within the newest version of OGH Herpetozoa introduced out by the Austrian Herpetological Society.
The authors of the research are Ht. Decemson, Hmar Tlawmte Lalremsanga, Premjit Singh Elangbam, Mathipi Vabeiryureilai, Parag Shinde, Jayaditya Purkayastha, Dmitriy V. Arkhipov, Andrey M. Bragin, and Nikolay A. Poyarkov.

“T. zaimeng was the outcome of an extraordinary mission that involved integrative taxonomic analysis, merging powerful tools of molecular research and morphological examination,” Prof Lalremsanga of Mizoram University’s Developmental Biology and Herpetology Laboratory instructed The Hindu.
He was a key driver of the research together with Dr. Poyarkov, who’s related to the Lomonosov Moscow State University and the Joint Russian-Vietnamese Tropical Research and Technological Centre at Hanoi.
The Tylototriton zaimeng had earlier been mistaken for its shut kinfolk — the T. himalayanus and the T. verrucosus. Phylogenetic evaluation revealed that the brand new salamander is a sister species of the T. panwaensis and T. houi present in northern Myanmar and southern China, respectively.
T. zaimeng was discovered to be a medium-sized salamander not like another. Its head is huge and large, with a rounded snout and protruding supratemporal bony ridges, whereas a well-developed sagittal ridge adorns its crown.
“The creature’s limbs, short and elegantly formed, did not overlap when adpressed along its body. A wide and unsegmented vertebral ridge ran along its back, accompanied by 13-14 pairs of rib nodules, marking a clear distinction from its kin,” the research mentioned.

“T. zaimeng displayed a stunning brown colouration, embellished with dull orange to yellowish-brown markings on its head, vertebral ridge, rib nodules, palms, soles, vent, and ventral tail ridge. Vomerine teeth, elegantly organized in two distinctly curved bell-shaped series, further differentiated this mysterious creature,” it mentioned.
The researchers advocated the inclusion of the brand new salamander species within the International Union for Conservation of Nature (IUCN) Red List as a weak species, emphasising the necessity for conservation efforts to guard it and its fragile habitat.
