We studied the morphological and genetic differences within Calotes jerdoni, a widespread species across northeast India. Our results suggest the presence of two distinct species in this region, one being Calotes jerdoni and the other being Calotes medogensis, which we report for the first time from India. We designate a lectotype for Calotes jerdo...

We report the rediscovery of Oligodon melaneus 112 years after its original description and document the third, and only non-type, specimen for the species. The new specimen was found 267 km east of the type locality (Tindharia, West Bengal state) from Assam state, India. We designate a lectotype for the species, and provide an extended description...

A new species of natricine snake of the genus Rhabdophis is described from Northeast India. Morphologically the new species is similar to Rhabdophis himalayanus but it can be distinguished from it by lacking a nuchal groove and nuchal glands, being relatively smaller, and having a distinct neck, ventral, and subcaudal coloration. In overall colorat...

We present an updated inventory of the reptilian fauna of Dampa Tiger Reserve based on two separate field surveys during March and September 2021. We recorded 33 species of reptiles which is about 27% of the total reptilian diversity recorded from the state. This includes new distribution records for 16 snake species with observations on rare speci...

We studied the breeding and nesting behaviour of the endemic terai tree frog, Polypedates taeniatus in Uttar Pradesh state of India. We describe amplexus, spawning, unique ground nesting behaviour, and larval developmental stages of the species. Comparative reproductive behaviour of foam-nesting rhacophorids from India is also provided. The present...

The libellulid dragonfly Indothemis carnatica is reported here for first time from Assam (Northeast India) based on photographic records, from the Jeypore Reserve Forest of Upper Assam.

Diversity and Distribution of herpetofaunal Species along Ganges River Basin, India.

Lycodon mackinnoni is a poorly known Himalayan endemic snake known from Western Himalaya. Since the original description of L. mackinnoni almost 112 years ago, this species was not reported from its type locality and its phylogenetic position remain unknown. We herein, provide detail morphological description, comparison with type material, phyloge...

We report a rare skipper butterfly from Kalesar National Park, Haryana, which is the first record for the state and the lowermost elevation record for the species.

Article is about carrion feeding by tadpoles of Nanorana vicina and Duttaphrynus himalayanus

Butterfly diversity and abundance depend on the diversity of foraging resources and nectar characteristics. Several wild plants of the family Asteraceae often considered as weeds, are important nectar sources for butterflies. The present communication reports Cirsium wallichii as a key nectar source for a large number of butterfly species during th...

The paper reports sequence of events observed during a competitive behaviour among calling males of Raorchestes shillongensis from Shillong, Northeast India.

The first case of Indian butterflies feeding on human blood is reported from Assam.

Manchabandha and Budhikhamari Reserve Forest are located in Mayurbhanj district of Odisha, India. These two reserve forests are Sal (Shorea robusta) dominated forests. We conducted study on butterfly diversity in Manchabandha and Budhikhamari Reserve Forest during December 2013 and November 2015. During this period, We recorded a total 135 species...

Redescription and geographic distribution of Raorchestes shillongensis (Anura: Rhacophoridae) from Meghalaya, Northeast India. Raorchestes shillongensis is a threatened rhacophorid frog endemic to Northeast India. The species is poorly known and systematic information is lacking. We redescribe here the morphology of the species from topotypic mater...

Herpetofauna and humans have interacted since ancient time in many aspects. These animals face numerous problems to survive with the urbanizing world. This becomes a great challenge for the conservation of the herpetofauna. Although many studies are being carried out on herpetofauna, very few studies have investigated the herpetofaunal interaction...

Diversity of Odonata and their habitat preference was studied in a landscape between Kaziranga National Park and Karbi Hills of Assam. During study period we recorded total 82 species of odonates from 51 genera and 10 families out of which, dragonfly (Anisoptera) represented by 43 species and damselfly (Zygoptera) represented by 39 species. Family...

The species Plastingia naga, de Niceville 1884is a very rare butterfly, and it occurs widely from Assam to Myanmar, Malay Peninsula, Sumatra, Borneo and Philippines (Evans, 1932). Except India, recently this species was recorded from Singapore, Sumatra and Thailand. On 10 Oct 2014 around 10:00hr, a solitary individual of Plastingia naga was sighted...

Among the insects, butterflies are the most taxonomically studied group and play key role in ecosystem as pollinators and bio-indicator species. A total of 136 species of butterflies belonging to 87 genera representing 5 families were recorded from two selected study sites in the fringe area of Similipal Biosphere Reserve during January 2014 to Nov...

The present study has been carried out in the Padmatola wetland of Balasore district of Odisha, India during December 2013 and May 2014. This study emphasises a checklist of total 51 species of odonata (Dragonflies and Damselflies). Among this the suborder anisoptera represented by 33 species with 22 genera from 4 families and suborder zygoptera re...

Ecological investigation of species diversity and abundance of birds was conducted from May 2014 to February 2015 in and around North Orissa University Campus. Transect count and point count methods were used to investigate the abundance of birds. Observation was conducted by periodically walking along the study area early in the morning and late i...

Odonates are represented by dragonflies and damselflies. Odonates variety in Manchabandha Reserve Forest was observed, where recorded a total of 48 species of odonates. The sub-order Zygoptera was represented by 15 species out of which Coenagrionidae was the richest family with 9 species. And sub-order Anisoptera was represents 33 species out of 33...
