Protosticta armageddonia sp. nov. is compared with all other known Protosticta species of the Western Ghats to provide comprehensive differential diagnosis. The new species is distinguished from its congeners by a combination of characters, including a marking on the ventral side of thorax, structure and colour of the prothorax, markings on the 8th abdominal segment, and the structure of caudal appendages and genital ligula. Furthermore, we provide preliminary information on the ecology and natural history of the new species.

Odonates (dragonflies and damselflies) are freshwater insects perceived as good ecological indicators. To investigate responses of tropical odonates to an urbanization gradient, we sampled adult odonates along an urbanization gradient at six sites along the Mula River across Pune City, Maharashtra, India. For species–habitat analysis, we first performed a variable reduction using principal component analysis. we analyzed species–habitat data using redundancy analysis and canonical correspondence analysis. We documented 15 odonates across 6 sites. Our statistical analyses on patterns of odonate assemblages across sites and environmental variables did not return significant results. However, we detected site-exclusivity in a few species based on occurrence data and identified urban sensitive, urban tolerant and generalist species. We found that the odonate diversity was highest a...

The Convention on Biological Diversity's (CBD) Aichi Target 19 states that "By 2020, knowledge, the science base and technologies relating to biodiversity, its values, functioning, status and trends, and the consequences of its loss, are improved, widely shared and transferred, and applied." One of the significant impediments mentioned in achieving the goals of CBD is lack of scientific information, which is substantiated by studies that highlight various gaps such as taxonomic, thematic, spatial and temporal biases in the global knowledge on biodiversity. Behind such global approaches to knowledge and its production, there is a need to establish a biodiversity knowledge commons at the global, regional and national scales. Biodiversity informatics is tightly integrated with...

Unfortunately, many of these species severely lack basic research, resulting in poor conservation strategies. The phylogenetic relationship of the Critically Endangered Forest Owlet Heteroglaux blewitti has been the subject of a century-old debate. The current classifications based on non-phylogenetic comparisons of morphology place the small owls of Asia into three genera, namely, Athene, Glaucidium, and Heteroglaux. Based on morphological and anatomical data, H. blewitti has been alternatively hypothesized to belong within Athene, Glaucidium, or its own monotypic genus Heteroglaux. To test these competing hypotheses, we sequenced six loci (~4300 bp data) and performed phylogenetic analyses of owlets. Mitochondrial and nuclear trees were not congruent in their placement of H. blewitti. However, both mitochondrial and nuclear combined datasets showed strong statistic...

Globally, disposal of fly ash is a great challenge for the planners. Dumping the ash in nearby wastelands is most preferred disposal method adopted by the agencies. In India, such depositions are often transformed in to varying sizes of ponds that are known as fly ash ponds. Out of the 8 major thermal power plants of Maharashtra, fly ash ponds associated with Nashik Thermal Power Station were explored as habitats for the faunal diversity. Despite the toxic nature of flyash, these sites harbour significant avian diversity (128 species). Interestingly, these ponds are situated in close proximity with Nandur-Madhyameshwar Bird Sanctuary along the Nandur-Madhyameshwar dam. This in fact encouraged a comparative study of avian diversity of both these man-made wetlands. The analysis based on field observations made during 2007-2011, shows high similarity value (0.75) between these habitats. Present study signifies th...

Tropical areas are high Odonata diversity areas. However, there has not been accumulation of extensive baseline data on spatial distribution of these insects from such places. Maharashtra, the third largest state of India, harbors a variety of land-use and occupies six biogeographic provinces. We carried out Odonata surveys in Maharashtra during 2006-2014. Compilation of all these studies along with other authenticated records resulted in a checklist of 134 species of Odonata belonging to 70 genera representing 11 families. The highest numbers of species were recorded from the Libellulidae (48 species) and Gomphidae (22 species) families. A previous study had reported 99 species of Odonata from the Maharashtra state considering records from early 1900's to 2012. Our observations across the state add 33 species to this list. Maharashtra forms a unique source of Odonata diversity and our observations support the importance of this ...

However, species responses may vary spatiotemporally and therefore, it is useful to establish species-habitat relationships at a regional level. To test if tropical urban odonates respond to seasons, and to explore species-habitat relationships with an emphasis on water pollution, I studied six wetlands in the city of Pune for a year. I also investigated whether combining data on dragonflies and damselflies, as is often done in many studies, skews the results. I recorded seasons, water pollution and habitat attributes as predictors of the odonate diversity and assemblage. I analyzed the data on dragonflies, damselflies and odonates (dragonfly-damselfly combined) separately for seasonal variation, and species-habitat relationships. I used multiple regression and canonical correspondence analyses. Forty-four species were recorded during the study. No seasonal var...

It is like a unique threat status identity for each species. It signifies that adequate amount of scientific work is done on the species so as to understand its ecology and natural history. Therefore, there is an urgent need to address the question on the knowledge gap on our odonates. One more thing to be emphasized is that current IUCN conservation assessments are too old for many species. If more of us, researchers and academicians, having a firsthand experience of odonate conservation, come forward to assess the conservation status of the species they have worked on, we will have contemporary assessments, which will be of great conservation value.
