The present study reports the first confirmed record of the Lesser Blue-wing Rhyothemis triangularis Kirby, 1889 from Udaipur District, Rajasthan, India. Previously unreported in the state, this finding significantly expands this dragonfly’s known geographical range into a new area. During the wetland monitoring program in September 2024, an opportunistic sighting of a dragonfly was observed in Jhadol and Gogunda, two adjoining blocks (tehsils) of Udaipur District. The previous findings of this species are mainly from the high rainfall zone, but the present finding is from a drier zone of western India, having low rainfall. The findings contribute to the understanding of the species distribution and ecological preferences, particularly in semi-arid regions like Jhadol and Gogunda block of Udaipur District. These findings contribute to the natural history of the species and highlight the habitat quality and suitability for this species in low-rainfall areas.
