Abstract
Beetles are crucial ecosystem components, serving as pollinators, decomposers, and predators. In 2023, a faunistic survey was conducted across 14 locations in Anjaw District, Arunachal Pradesh, India, a region of rich biodiversity. Coleopteran specimens were collected using light traps, hand-picking and D-type water nets. Identification of the specimens revealed 70 beetle species belonging to 49 genera and 12 families. Among the identified species, 17 represent new records for Arunachal Pradesh, significantly enhancing our understanding of the state's beetle diversity. Continued exploration of lesser-studied areas in Arunachal Pradesh is expected to reveal further additions to the Coleopteran fauna.
