Protosticta Selys is a genus of damselflies of the family Platystictidae Kennedy found in forests of tropical Southeast Asia. The genus Protosticta has rarely been reported from Northeast India. In this paper, we describe Protosticta khasia sp. nov. (subfamily Protostictinae Dijkstra et al.) based on holotype male and paratype female collected from Maraikaphon, East Khasi Hills district, Meghalaya, India. Protosticta khasia can be identified by the markings of the prothorax and the shape of the male paraproct with two arms. We also describe Yunnanosticta siangi sp. nov. (subfamily Sinostictinae Wilson) from Arunachal Pradesh, India, based on two males and two females. This species is differentiated from its congeners by the thoracic and abdominal markings as well as the shape of male caudal appendages. The key for males of Yunnanosticta is provided. Additionally, we provide new records of Protosticta samtsensis Gurung \& Phan, along with an updated key to the Protosticta species of Northeast India.

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 (prominent lateral spines on cerci) and the lateral thoracic markings (stripe on mesepisternum reduced and pointed anteriorly). Additionally, B. chaukulensis is unique in terms of the shape of hamuli, strongly angulated with spines at both sides. An updated identification key to Indian Burmagomphus spp. is also provided.

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-term surveys to study odonate diversity of the Karimganj District, Assam, India bordering the states of Tripura and Mizoram, and the country of Bangladesh. Here, we publish reports of eight species: four new to India Ceriagrion calamineum, Nannophyopsis clara, Phyllothemis eltoni, and Zyxomma breviventre, and four noteworthy species newly recorded from the state: Megalogomphus smithii, Orientogomphus indicus, Pseudothemis zonata, and Sarasaeschna khasiana. We recorded total 97 odonate species during our surveys. We provide the checklist of Odonata of Assam based on our surveys and literature.

A modified and expanded definition of the Drepanosticta carmichaeli-group is given. This includes the species: D. annandalei Fraser, 1924, D. brownelli Tinkham, 1938, D. carmichaeli (Laidlaw, 1915), D. emtrai Dow, Kompier Phan, 2018, D. hongkongensis Wilson, 1997, D. jurzitzai Hmlinen, 1999, D. sumatrana Sasamoto Karube, 2007, D. tenella Lieftinck, 1935, D. vietnamica Asahina, 1997 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. carmichaeli and variation in D. carmichaeli is discussed. Drepanosticta wildermuthi sp. nov. from the Central Highlands of Vietnam (holotype male from Bao Loc district, Lam Dong Province) is described. The female of D. jurzitzai Hmlinen, 1999 is described for the first time. A key to the males of the Drepanosticta carmichaeli-group is provided.

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 ofBrachythemis contaminatafrom South Asia.We describe the morphological variation between andromorph and heteromorph females, and collate records of andromorph females from various sources. Yearly number of andromorph female ofCrocothemis servilia, Urotemis signataandNeurothemis signatawas calculated using records form published literature and unpublished sources, and social media.

We compare these three new species with other Protosticta spp. from the Western Ghats based on new material and provide comprehensive differential diagnoses with determination key for males of all species occurring in the Western Ghats. The taxonomic validity of P. mortoni Fraser, 1922 is established with fresh specimens from Hassan, Karnataka, and rediscovery of P. rufostigma Kimmins, 1958 is reported from Kanyakumari Wildlife Sanctuary, Tamil Nadu.

The fauna of British India, including Ceylon and Burma: Odonata (Vol. 1). London: Taylor and Francis.) doubted the taxonomic necessity of this taxon. His notion of Aciagrion hisopa (Selys, 1876) was erroneous, as evidenced by syntypes of this species in Selys{\textquoteright} collection, so the ssp. krishna is not conspecific with A. hisopa. Topotypic specimens of ssp. krishna from the Western Ghats were compared to specimens of Aciagrion approximans (Selys, 1876) from the Khasi Hills, Meghalaya, which are topotypical because of the recent designation of the neotype of this species in Selys{\textquoteright} collection. These two series were found to be very close to each other but differing at the level of subspecies, so we propose a new subspecies status and combination, Aciagrion approximans krishna Fraser, 1921 Fraser, F.
