Introduction
I have been working on diversity and ecology of Indian Odonata (Dragonflies and Damselflies) in India for a decade. I'm also an editor of the citizen-science website www.indianodonata.org Currently, I am pursuing PhD in Biological Sciences from University of Arkansas, USA.

Article
Full-text available
Anormogomphus heteropterus is redescribed based upon a single male specimen. Discrepancies and inaccuracies in previous illustrations of this species that could cause confusion are pointed out. Platygomphus benritarum sp. nov. is described on the basis of a single male specimen collected at Tezpur, Sonitpur District, Assam, India. Platygomphus benr...

We describe a new species of dragonfly, Burmagomphus chaukulensis sp. nov., based on four males and two females from Chaukul, Sindhudurg, Maharashtra located in the Western Ghats biodiversity hotspot of India. The newly described species is diagnosed from its congeners by a combination of following characters: the shape of male caudal appendages (p...

A modified and expanded definition of the Drepanosticta carmichaeli-group is given. This includes the species: D. and D. wildermuthi sp. nov.). The species of the group are reviewed and in most cases illustrated, diagnostic notes are given wherever possible. Drepanosticta polychromatica Fraser, 1931 is considered to be a junior synonym of D. carmic...

Situated at the intersection of the Himalayan and Indo-Chinese biodiversity hotspots, Northeast India is one of the most biodiversity rich areas of South Asia. Despite this, insects such as dragonflies and damselflies (Order: Odonata) of this region remain poorly studied causing an impediment to their conservation assessments. We conducted long-ter...

Three new species of Protosticta Selys, 1885 (Odonata: Zygoptera: Platystictidae) from the Western Ghats biodiversity hotspot in India: P. cyanofemora sp. nov. (wet evergreen forests in Shendurney Wildlife Sanctuary, Kollam, Kerala and Kalakkad Mundanthurai Tiger Reserve, Tirunelveli, Tamil Nadu), P. myristicaensis sp. nov. (Myristica swamp at Kath...
Article
Full-text available
Polymorphism has rarely been reported from dragonflies of the Libellulidae (Odonata: Anisoptera) family. Here, we report female-limited polymorphism in females of five species of the Libellulidae and a gynandromorph male of Brachythemis contaminata from South Asia. We describe the morphological variation between andromorph and heteromorph females,...

A group of Indian scientists including botanists, entomologists, ornithologists, mammalogists, herpetologists, aquatic fauna specialists, hydrologists, geographers, and social scientists, many with research experience in northeastern India, including the Dibang Valley in Arunachal Pradesh, have conducted a peer-review of the Technical Report prepar...

Bradinopyga konkanensis sp. nov. is described based on three males and one female collected from the coastal region of Maharashtra, India. Important characters are illustrated and compared with morphologically similar species Bradinopyga geminata (Rambur, 1842), Indothemis carnatica (Fabricius, 1798), and Indothemis limbata sita Campion, 1923. Brad...
Article

1. Damselflies often show intra‐specific colour variation, which may represent genetic polymorphism or age‐related (ontogenic) colour changes. 2. Such variation has distinct implications for the species' ecology and evolution. Colour variation in females of the damselfly Agriocnemis pygmaea was studied, which range from blue male‐like individuals (...

Ceriagrion chromothorax sp. nov. is described from Western Ghats, India, based on six males and one female collected from Sindhudurg District of Maharashtra.
Article

Cephalaeschna acanthifrons sp. nov. collected from Eaglenest Wildlife Sanctuary, West Kameng District, Arunachal Pradesh, India, and Planaeschna poumai sp. nov. collected from two localities in Senapati District, Manipur, India, are described and compared with congeneric species. These records also represent the first reports of these obscure gener...

Pseudothemis zonata (Burmeister, 1839) and Burmagomphus divaricatus Lieftinck, 1964 are reported for the first time from northeastern India—hitherto not reported from the west of Thailand. The female of Anisopleura vallei St. Quentin, 1937, is described for the first time, with new records of this species from four localities in Kohima District, Na...

Aciagrion Selys, 1891 is one of the taxonomically difficult and poorly known genera of Oriental damselflies. Aciargion hisopa race krishna Fraser, 1921 was described from Mahabaleshwar, Maharashtra, India. However, later Fraser (1933) doubted the taxonomic necessity of this taxon. His notion of Aciagrion hisopa (Selys, 1876) was erroneous, as evide...

We surveyed odonates in the districts of Kohima, Peren and Wokha in the state of Nagaland, northeastern India, during April and May 2012 and May 2013. We recorded 69 species, including 43 additions to the known odonates of Nagaland, and one addition— Calicnemia erythromelas Selys, 1891—to the Indian odonate fauna. The known odonate fauna of Nagalan...

Project
To create a network of forward-looking taxonomists, systematists and evolutionary biologists who collaborate to advance taxonomic discovery, molecular systematics and phylogenomic studies on Indian biodiversity, especially insects and other invertebrates. Here is one of the resources that we have created: http://collections.ncbs.res.in/, and here are some of our publications: http://collections.ncbs.res.in/publications.
Project
To document (observe, photograph, record, note behavior etc.) and upload observations to citizen science portals (such as iNaturalist) and publish articles describing various taxa as well as use the data for further research. I have done a lot of work by myself as well as with other co-workers. The background of my personal involvement in biodiversity documentation is here: https://the-sparrowsnest.net/2020/04/29/all-things-bright-and-beautiful/
