With over, 13,000 species globally, water beetles exist in almost all types of freshwater habitats, such as rivers, springs, lakes, ditches, puddles, seeps, and groundwater. We examined over 121 water beetle samples from Dhurwa Dam, situated in Indian state of Jharkhand. The identification of the specimens yielded 15 species belonging to 12 genera and 3 families, Noteridae (1 species), Dytiscidae (6 species) and Hydrohilidae (8 species), which are reported for the first time from Dhurwa Dam. Additionally, Cybister sugillatus Erichson, 1834, Leiodytes orissaensis (Vazirani, 1969) and Sternolophus rufipes (Fabricius, 1792) are reported for the first time from Chota Nagpur Plateau in Jharkhand state. These results are based on recent collections, including observation notes on the species habitat. This study is intended to contribute to an appropriate discussion of the diversity of water beetles in the future. With intensive surveys of unexplored areas such as the Chota Nagpur Plateau in the state of Jharkhand, more species of water beetles are expected in the future.
