The cicadas of the Indian subcontinent, like many other insects in region, have remained understudied since early part 20th Century, and await modern taxonomic, systematic phylogenetic treatment. This paper presents an updated catalogue (Hemiptera: Cicadidae) from India, Bangladesh, Bhutan, Myanmar, Nepal Sri Lanka, first over a century.
A new species of vine snake the genus Ahaetulla is described from peninsular India. The taxon a medium-sized arboreal snake, readily distinguished all other congeners by morphological and genetic differences. appears to be widely distributed in Eastern Ghats Central India with western-most distribution extending into eastern Rajasthan. However, it relatively rare, only three specimens being acquired over past nine...
The montane agamid lizard genus Oriocalotes is currently considered monotypic, represented by the species, O. paulus. systematic status of this taxon has remained questionable since its initial descriptions in mid-1800s. A detailed molecular and morphological study was carried out to assess validity genus, position within Asian subfamily, Draconinae. Freshly collected historical museum specimens from type locality paulus were examined morphologically, along with additional samples localities...
We describe a new species of fan-throated lizard the genus Sitana from Deccan peninsula India. The is sivalensis clade and can be readily diagnosed morphologically S. sivalensis, fusca schleichi by having dewlap extending beyond forearm insertion. differs all other congeners in combination morphological characters such as feebly serrated with dark blue line on throat adult males (versus well bright patch orange spots ponticeriana complex), small body size large gokakensis thondalu)...
Three new species of the Asian genus Mata Distant, 1906 (Hemiptera: Cicadidae) viz. lenonia sp.nov.; ruffordii sp.nov. and meghalayana are described from Indian state Meghalaya. Keys taxonomic descriptions these provided with detailed accounts their natural history acoustics.
The cicadas (Hemiptera: Cicadidae) related to tribe Cicadini exhibit some of the most remarkable phenotypes in family, with many genera possessing striking colour patterns and unusual morphological features. This largely Asian group 13 tribes has proven challenging for cicada taxonomists, part because likely convergent evolution or losses these phenotypes. We present first focused molecular phylogeny this clade, including ~60 described genera. genetic dataset contains 839 ingroup-informative...
Protosticta Selys is a genus of damselflies the family Platystictidae Kennedy found in forests tropical Southeast Asia. The has rarely been reported from Northeast India. In this paper, we describe khasia sp. nov. (subfamily Protostictinae Dijkstra et al.) based on holotype male and paratype female collected Maraikaphon, East Khasi Hills district, Meghalaya, can be identified by markings prothorax shape paraproct with two arms. We also Yunnanosticta siangi Sinostictinae Wilson) Arunachal...
Eastern Himalaya and northeastern India are part of two global biodiversity hotspots, yet the critical butterfly-plant associations early stages most butterfly species in this region poorly recorded. We have reported larval host plants 78 species, some which rare endemic, providing specific information on spatial temporal details associated with these records. These records contribute region-specific Indian butterflies, may be useful basic ecological conservation studies future.
Lahugada dohertyi is one of the many lesser-known cicadas northeastern India which has never been studied since its discovery. Recently, a century later, population this elusive cicada was discovered in northern West Bengal. This paper gives an account on distribution Bengal, taxonomy, and natural history suggests common name based call habitat preferences.
The United Nations Educational, Scientific and Cultural Organization (UNESCO’s) World Heritage Convention, adopted in 1972, encourages to identify conserve unique invaluable sites of global significance. These are recognized by their outstanding universal value (OUV). This article adapts takes up a detailed qualitative analysis on the status, trend challenges keeping intact key OUV five natural WHSs India using questionnaire survey, respondents were forest frontline staff community...
The genus Becquartina Kato, 1940 (Hemiptera: Cicadidae) is reported for the first time from India with a new species, bicolor sp. nov., along records of two distinct colour forms, northeastern Indian state Meghalaya and located within Indo-Burma Biodiversity hotspot. This paper provides an account its natural history bioacoustics. present discovery extends distributional range Southeast Asia into Northeast increases total number known species to seven.
The Indian Himalayan Region (IHR) is known for its biodiversity, yet it faces substantial threats fromanthropogenic activities and climate change. Despite the ecological importance of IHR, herpetofaunal studies,especially in eastern State Sikkim, remain limited. We herein address aspects natural history ofa fossorial snake, Günther’s Oriental Slender Snake (Trachischium guentheri) North Sikkim. encountered 25snakes during field surveys from 30 September to 12 October 2023 Lachen region at...
A new genus of cicada, Sahyaterpnosia gen. nov., is described from the subtropical hill forests southern Western Ghats Peninsular India. We place in tribe, Leptopsaltriini Moulton, 1923. The can be distinguished all other genera by following combination characters: hindwing with six apical cells; timbal cover minute, abdominal sternites III & IV without tubercles; posterior margin male tergite III, wider than mesonotum; basal lobe pygofer lobes, ill-defined, substantially confluent margin,...

In order to broaden our understanding about cicada diversity of northeastern India, a comprehensive survey was conducted in the year 2017, Garo, Khasi, and Jaintia hills Meghalaya an occasional opportunistic carried out northern West Bengal Arunachal Pradesh. During these surveys, we came across four species cicadas, viz., Meimuna duffelsi, Dundubia annandalei, Balinta tenebricosa, Orientopsaltria fangrayae, which were not reported from India earlier among them genus is being for first time...
We report the occurrence of Wroughton’s Small Spiny Mouse Mus phillipsi Wroughton, 1912 based on a specimen collected from Gajapati District, Odisha. With this species, diversity order Rodentia in Odisha increases to 17 species under three families and 12 genera. An updated checklist rodents with distribution localities threats various is also presented.
