Item Notes on the oviposition behaviour of three Elattoneura damselflies from India (Odonata: Platycnemididae)(Odonatologica,, 2021) Neha Mujumdar ., Ameya Deshpande ., Prosenjit Dawn ., Pankaj Koparde .,Oviposition behaviour of three Indian Elattoneura spp. is described and discussed. Endophytic oviposition in dry rigid substrates away from water by the endemic E. nigerrima and E. tetrica is recorded; this differs from the typical recorded use of submerged vegetation substrates in the genus. Contrasting behavioural observation of oviposition in E. campioni is also discussed.Item Dragonflies and damselflies (Insecta: Odonata) of West Bengal, an annotated list of species(Oriental Insects,, 2022) Prosenjit Dawn .,An updated checklist of Odonata known so far from the state West Bengal is presented here consisting 239 species belonging to 114 genera and 17 families. Eight species viz. Megalestes irma, Lestes garoensis, Calicnemia nipalica, Chlorogomphus mortoni, Somatochlora daviesi, Cephalaeschna viridifrons, C. triadica, Lyriothemis mortoni, are recorded for the first time from the state; and last two species are recorded for the first time from India. This paper indicates a prominent rise in the number of species than the previous published checklist, as many isolated species distribution records were lying undocumented. This paper also reflects the data from citizen science platforms and social media groups. Reference for the original descriptions, type locality and information of specimen repository of the recorded species are provided. Some doubtful identification and distribution records are also discussed here.Item Description of the Last Instar Larva of Platylestes platystylus (Rambur, 1842) from Kerala, India (Odonata: Lestidae)(Zootaxa,, 2023) Chandran A.V.;Jose S.K.;Dawn P.The description of the final instar larva and the subsequent exuvia of Platylestes platystylus (Rambur, 1842) is given based on a single male larva collected from Kerala and reared in the laboratory. A brief account of the habitat of the damselfly and an updated key to the larvae of genera of Family Lestidae Calvert, 1901 are also provided.Item Description of the final instar larva of Aethriamanta brevipennis (Rambur, 1842) [Odonata: Anisoptera: Libellulidae] from Kerala(Zootaxa, 2025) AYIKKARA VIVEK CHANDRAN, SUBIN KANIYAMATTATHIL JOSE, PROSENJIT DAWNThe final instar larva and exuvia of Aethriamanta brevipennis (Rambur, 1842) is described from Thumboor Wetlands, Kerala. This Asian species bears dorsal spines on S5–8, short lateral spines on S8–9; labium has 12–12 premental setae and 7–7 palpal setae. Numerous long, hair-like setae are present all over the body, distal abdominal segments being most setose; setae also present on tibiae of all legs, wing-pads and posterior margin of head.
