چکیده:   (4198 مشاهده)
The diversity and heterogeneity of Odonata was studied at 10 sites located across almost all parts of the Bankura district (except northwestern and northeastern boundary regions), in the state of West Bengal, India from July 2015 to June 2022. Analysis of variance and rarefaction was performed to study the β-diversity and compare the taxa abundance at the sites to understand the heterogeneity of Odonata observations. The seasonality of the species and their site-wise distribution were also studied. A total of 74 odonate species belonging to eight families, represented by 46 genera were recorded. The study adds 17 species to the known Odonata fauna of Bankura district, including the addition of Microgomphus torquatus (Selys) to the fauna of West Bengal. It also confirms the addition of Ictinogomphus kishori to the known Odonata fauna of West Bengal, which has been confused with and misidentified as Ictinogomphus distinctus for long, the latter being described from the state of West Bengal and is also found in the region adjacent to the study area. Most recorded odonates belonged to the family Libellulidae (29 species), followed by Coenagrionidae (19 species), Gomphidae (nine species), Platycnenididae (six species), Aeshnidae (five species), Macromiidae (three species), Lestidae (two species), and Chlorocyphidae (one species). Species diversity and abundance assessments are essential for conserving the habitats of the restricted and endemic (to peninsular India) species.
