The present study was carried out in Digha-Shankarpur estuary region of Purba Medinipur district, West Bengal, India, during December 2018 to August 2020. During survey period, a total of 178 species of birds were recorded from the area including 29 previously unreported species from Purba Medinipur coast. With the compilation of previously published records and present records, the number of known avifauna of the coastal area of Purba Medinipur district goes to 225. Study also reveals the presence of nine near threatened and one vulnerable bird in the Purba Medinipur coastal area. Some of the new and noteworthy records are given in detail.

The present study was carried out to prepare a checklist of butterflies in the Coastal areas of Purba Medinipur District of southern West Bengal between January 2014 and February 2016. A total of 112 butterfly species belonging to 74 genera under 14 subfamilies and five families were recorded during the study period. Nymphalidae and Lycaenidae were the most dominant family, whereas Papilionidae was the least dominant family. Among 112 butterfly species recorded, 9 species were legally protected under the Wildlife (Protection) Act, 1972. A total of 59 species were newly recorded in the study area. Suastus minuta Moore, 1877 was recorded for the first time in West Bengal. The present results also provide a detailed comparison of butterfly diversity among different studies conducted in southern West Bengal.   Citation: Payra A., Mishra R. K., Mondal K., 2017.

A new species of Protosticta Selys, 1885 (Odonata: Zygoptera: Platystictidae) is described based on two male specimens collected from Kerala, at the southern end of the Western Ghats in India. We compared P. armageddonensis sp. nov. with the three closely similar Protosticta species recently described from the Western Ghats, namely P.anamalaica Sadasivan, Nair & Samuel, 2022, P. cyanofemora Joshi, Subramanian, Babu & Kunte, 2020, and P. monticola Emiliyamma & Palot, 2016, to provide comprehensive differential diagnosis. The new species is distinguished from its congeners by a combination of characters, including the structure of prothorax, caudal appendages, genital ligula, and markings on the 8th abdominal segment. A revised key of Protosticta spp. of the Western Ghats, based on mature male specimens is provided.

The large forest dwelling libellulid dragonfly Camacinia harterti Karsch, 1890 is recorded from Arunachal Pradesh and India for the first time in 115 years.  The present record is based on a single male specimen collected from Namdapha Tiger Reserve, Arunachal Pradesh, India.  We provide detailed diagnostic characters in photographs and information on the global distribution of the species.

The Indian Elattoneura are a difficult group to identify due to their extreme morphological similarity and sparse information in identification keys and on geographical distribution. The ambiguity is prominent among two Peninsular Indian Elattoneura species, E. nigerrima (Laidlaw, 1917) and E. tetrica (Laidlaw, 1917), described a hundred years ago. Both species were described based on male specimens with scant information on their females. The species are IUCN Red-listed, E. nigerrima (Data Deficient) and E. tetrica (Least Concern). Hitherto it was thought that E. nigerrima was smaller than E. tetrica and both have non-overlapping geographical distribution. Here, we re-described both sexes of E. nigerrima; E. tetrica along with morphometric data and geospatial analysis. We found that E. nigerrima is significantly larger than E. tetrica. The species are largely allopatric in distribution, with the former having a much wider spatial distribution than previously thought. Based on our geospatial analysis, we provide occurrence data useful for the future IUCN assessments of E. nigerrima and E. tetrica. We highlight the importance of updating taxonomic status information and data on spatiotemporal distribution to proceed with the conservation of endemic insects such as Elattoneura damselflies. Our study indicates reassessments of Indian Odonata species are urgently needed.
