Introduction
I'm amazed by the evolving biodiversity and its maintenance. As a model, I study arachnid evolution using advanced genomic and transcriptomic technology, in the hope of finding patterns and understanding the patterns of exceptions. During weekends, I play with little codes to test any potential in my developing philosophy about testing evolutionary hypotheses. Once a month, I engage with citizen scientists across Asia and help documenting spiders (e.g. SpiderIndia group on Facebook), a long-term initiative to document spiders from south Asia.

Article
Phylogenomic methods have proven useful for resolving deep nodes and recalcitrant groups in the spider tree of life. Across arachnids, transcriptomic approaches may generate thousands of loci, and target‐capture methods, using the previously designed arachnid‐specific probe‐set, can target a maximum of about 1,000 loci. Here, we develop a specializ...

Genome-scale data sets are converging on robust, stable phylogenetic hypotheses for many lineages; however, some nodes have shown disagreement across classes of data. We use spiders (Araneae) as a system to identify the causes of incongruence in phylogenetic signal between three classes of data: exons (as in phylotranscriptomics), non-coding region...
Article
High throughput sequencing and phylogenomic analyses focusing on relationships among spiders have both reinforced and upturned long‐standing hypotheses. Likewise, the evolution of spider webs—perhaps their most emblematic attribute—is being understood in new ways. With a matrix including 272 spider species and close arachnid relatives, we analyze a...

Asymmetrical rates of cladogenesis and extinction abound in the Tree of Life, resulting in numerous minute clades that are dwarfed by larger sister groups. Such taxa are commonly regarded as phylogenetic relicts or "living fossils" when they exhibit an ancient first appearance in the fossil record and prolonged external morphological stasis, partic...

Taxonomic monographs synthesize biodiversity knowledge and document biodiversity change through recent and geological time for a particular organismal group, sometimes also incorporating cultural and place-based knowledge. They are a vehicle through which broader questions about ecological and evolutionary patterns and processes can be generated an...
Article
We address the phylogenetic relationships of pimoid spiders (Pimoidae) using a standard target-gene approach with an extensive taxonomic sample, which includes representatives of the four currently recognized pimoid genera, 26 linyphiid genera, a sample of Physoglenidae, Cyatholipidae and one Tetragnathidae species. We test the monophyly of Pimoida...
Article
Hickmania troglodytes is an emblematic cave spider representing a monotypic cribellate spider genus. This is the only Australian lineage of Austrochilidae while the other members of the family are found in southern South America. In addition to being the largest spider in Tasmania, Hickmania is an oddity in Austrochilidae because this is the only l...
Article
A new thread-legged assassin bug species, Myiophanes (Myiophanes) wygodzinskyi sp. nov. (Hemiptera: Heteroptera: Reduviidae: Emesinae: Emesini), collected from Ravana Cave in Uva Province of Sri Lanka, is described. It is the largest species of the genus described so far.

S1 Supplementary material for: Thorpe et al. 2018. Climate structuring of Batrachochytrium dendrobatidis infection in the threatened amphibians of the northern Western Ghats, India Journal manuscript number: RSOS-170810
Article
Full-text available
Batrachochytrium dendrobatidis (Bd) is a pathogen killing amphibians worldwide. Its impact across much of Asia is poorly characterized. This study systematically surveyed amphibians for Bd across rocky plateaus in the northern section of the Western Ghats biodiversity hotspot, India, including the first surveys of the plateaus in the coastal region...
Article
Full-text available
The importance of patch quality for amphibians is frequently overlooked in distribution models. Here we demonstrate that it is highly important for the persistence of endemic and endangered amphibians found in the threatened and fragile ecosystems that are the rocky plateaus in Western Maharashtra, India. These plateaus are ferricretes of laterite...

Patil Sangludkar Mahavidyalaya, Daryapurand Satpuda Foundation at Hotel Gauri Inn, Amravati, Maharashtra, India. Some 126 participants from 20 countries registered for the conference. Joseph Koh was elected as the ne...

A new cavernicolous, thread-legged assassin bug, Bagauda ernstmayri sp. nov. (Hemiptera: Heteroptera: Reduviidae: Emesinae), collected from a cave near Satara, in the Western Ghats of Maharashtra, India, is described. Its interaction with the web of an uloborid spider Zosis geniculata (Olivier, 1789) (Araneae: Uloboridae) is discussed.

A new species of the genus Pseudopoda is described from India: Pseudopoda ashcharya sp. n. Males are characterised by the absence of the conductor and females are unique within the genus in having the lateral lobes of their epigyne fused. The systematic relationship of the new species is discussed referring to its isolated occurrence in the Western...

Background: While surveying bugs and spiders in the caves of Satara District, Maharashtra, one of us (SK) collected a thread-legged bug associated with a spider web. New information: A Sri Lankan Emesinae bug, Myiophanes greeni Distant (Heteroptera: Reduviidae: Emesinae) is reported for the first time from India. The species is redescribed with...

Recent restrictions and regulations put on the animal dissections in academic curricula of life sciences at the undergraduate and postgraduate levels have met with a lot of criticism from researchers and university/college teachers. Substitution of invasive species for regulated dissections in the present curriculum can be a good strategy for both...
Article
Iodine gives a deep yellowish brown color in aqueous solution. As acetone is iodinated and Iodine is converted to iodide ion, this color slowly fades as iodine is consumed. Thus iodination of acetone can be investigated by the change in absorbance. In the present investigation, kinetics of this reaction has been studied colorimetrically. The ext...

Description of Thomisus telanganaensis Pravalikha & Srinivasulu, 2015 based on two females and their interpretation as intraspecific variation, are likely to be distinct Thomisus species. Further, the proposed endemicity of poorly studied species Thomisus projectus Tikader, 1960 in Pravalikha & Srinivasulu (2015) is doubtful and based on distributi...

Most of the limnological studies in India have focussed on a few taxa of large, permanent water bodies, and pond ecosystems, and related temporary water bodies are neglected. We present here a faunal inventory, with representative photographs, for a single, small temporary pond, reporting over 125 species of strictly aquatic fauna and 25 species of...

Question
A huge proportion of fauna is unrecorded/ undescribed yet, mainly in invertebrates from tropical region. Hundreds of groups and individuals on Facebook, iNat, Flickr etc, have been photographing animals, some of which have not been recorded in the scientific publications.
While the names provided as identification to these images might not always be correct (as sampling is must for id in many groups), how are they contributing to biodiversity studies? 
Question
As a part of understanding distribution of spiders belonging to genus Tylorida with its taxonomic revision, I am trying to find researchers who would be interested to participate from Africa and Madagascar group of islands.
