New moth genus discovered in Kerala's Idukki reveals hidden biodiversity of Western Ghats
A team of researchers has discovered a new genus and species of tiger moth in the southern Western Ghats, highlighting the region's poorly known insect diversity. The discovery was published in the peer-reviewed Journal of the Lepidopterists' Society.
The new species has been named Antaram idukki, belonging to the tiger moth subfamily Arctiinae (Erebidae). It was found in Kerala's Idukki district. The study was conducted by an international team including scientists from the Zoological Survey of India (ZSI), the Natural History Museum in London, and independent naturalists.
According to the researchers, descriptions of entirely new genera are significant because they indicate the presence of previously unknown evolutionary lineages. "Descriptions of new genera are relatively rare, especially in the subfamily Arctiinae," they said. The name Antaram is a Sanskrit word meaning 'difference,' reflecting its distinct characteristics.
The new genus is currently known only from Idukki and is distinguished from related genera by unique external and genital morphological features. The researchers noted that the moth appears to be extremely rare, and its larval host plant and life history remain unknown. They warned that habitat degradation and vegetation changes may threaten its survival before its biology is fully understood.
Moths are highly diverse insects that play key ecological roles as pollinators and as a major food source for many animals. This discovery underscores the often-overlooked importance of insects and other invertebrates to ecosystem functioning.
Idukki is located in the Western Ghats, a UNESCO World Heritage site and one of the eight 'hottest hotspots' of biological diversity. Despite its ecological significance, the region faces growing pressures from unregulated tourism, habitat degradation, land-use change, and human-wildlife conflict. The researchers emphasized that the discovery highlights the need to protect these ecosystems and their still-unknown species.
