Abstract

The present study provides an updated record checklist of Odonata in the coastal regions of Purba Medinipur District, West Bengal. A total of 60 species (59 identified to species level and one unidentified Agriocnemis sp.) belonging to 40 genera and seven families were recorded. Twenty-five species of Zygoptera (damselflies) were classified under three families: Coenagrionidae, Lestidae, and Platycnemididae, represented by 17, three, and five species, respectively. Thirty-five species of Anisoptera (dragonflies) were classified under four families, with Libellulidae accounting for 28 species, Aeshnidae and Gomphidae for three species each, and Macromiidae for one species. Notably, Disparoneura quadrimaculata was recorded for the first time from Purba Medinipur, District, extending its known range within southern West Bengal. The highest species richness and density were observed during the monsoon season.
