Three new species of rove beetles have been discovered in Arunachal Pradesh, highlighting its immense yet largely untapped biological diversity.
According to a study published in the journal Soil Organisms, the discoveries pertain to three species belonging to the genus Megalopinus, namely Megalopinus arunachalensis, Megalopinus mithun, and Megalopinus micros.
The discovery came as a result of joint efforts undertaken by researchers at Rajiv Gandhi University and University of Tübingen.

Hidden diversity in fragile forest ecosystems
As per the study, the new beetles were discovered in forest areas like dead logs and wet leaf litter, which is critical for biodiversity conservation.
The field surveys were conducted in environmentally sensitive regions such as Pakke Tiger Reserve and Eaglenest Wildlife Sanctuary, known for their remarkable diversity of species.
The research group comprised Hiren Gogoi, Tagam Dobiam, and Sonu Singh from Rajiv Gandhi University, and Professor Oliver Betz and Tobias Mainda from Germany.
It is believed that Arunachal Pradesh is one of the under-explored states in India concerning insects, implying that numerous other species might have been overlooked until now.
