Itanagar: In a significant addition to the Eastern Himalayan biodiversity record, researchers have identified three previously undocumented species of rove beetles in the forest ecosystems of Arunachal Pradesh, underlining the region's rich but largely unexplored insect life.
The discovery, detailed in the journal Soil Organisms, introduces three new species within the genus Megalopinus-Megalopinus arunachalensis, Megalopinus mithun, and Megalopinus micros.
The study was carried out through a collaborative effort between scientists from Rajiv Gandhi University and the University of Tübingen.
The research team included Hiren Gogoi, Tagam Dobiam and Sonu Singh from RGU, along with Professor Oliver Betz and Tobias Mainda from the German institution.
Field observations revealed that the newly identified beetles inhabit forest microhabitats such as decaying wood and moist leaf litter.
Specimens were recorded in biodiversity-rich zones like Pakke Tiger Reserve and Eaglenest Wildlife Sanctuary, both known for their ecological significance.
Researchers noted that these fragile ecosystems require sustained conservation attention, especially as Arunachal Pradesh continues to remain one of the least explored regions for insect diversity.
They emphasised that continued scientific surveys could lead to the discovery of many more unknown species, contributing to a deeper understanding of ecosystem dynamics.
The findings were made available online on April 1.
Reacting to the development, Arunachal Pradesh Deputy Chief Minister Chowna Mein said the discovery highlights the state's exceptional natural wealth.
He noted that rove beetles, belonging to the Staphylinidae family, play a crucial role in ecosystems as predators and decomposers, and stressed the need to protect the state's pristine forest habitats.
Mein added that each new scientific discovery reinforces the urgency of conserving Arunachal's unique ecosystems, which continue to shelter rare and diverse species.
