The list is compiled following Platnick's The Raghavendra (2001) on spiders of Western Ghats. The lists are World Spider Catalog. Extensive search of scientific peer- reviewed publications in the region revealed 40 new species, mostly based on Tikader's checklist. This present checklist is which are not included in Platnick's list. The checklist is an attempt to clarify and standardize spider fauna list in India. compared extensively with Tikader's list. In all, 1442 species of spiders in 59 families have been listed as described formally History of arachnological studies in India from India. Taxonomic verification is recommended for 51 Arachnological studies in India started in the late 19th Century species. Seventy-nine species listed by Tikader do not occur in India. Fifty-three species listed by Dyal and included in with pioneer taxonomists such as Blackwall (1864, 1867), Platnick's list do not occur in India. The paper lists Stoliczka (1869), Thorell (1877), Cambridge (1892, 1897), Simon replacement names, incertae sedis, nomina nuda, nomina (1897a,b), Pocock (1895, 1899a,b, 1900a,b, 1901), and Sherriffs dubia, transfers, synonyms, wrong taxonomic placements, (1919, 1927, 1928, 1929). These taxonomists mostly studied Dyal's species, etc. The checklist is updated up to 15 August preserved specimens. The first spider to be described from 2005. India was Sphasus lepidus Blackwall, 1864 [= Oxyopes lepidus KEYWORDS (Blackwall, 1864)] along with six other spiders (Blackwall, 1864). Arachnida, Araneae, checklist, India, Platnick, review, F.H. Gravely, assistant superintendent of the Government spiders, Tikader Museum in Madras studied spiders in the wild and was the first taxonomist to publish new descriptions in India. His major The current world list of spiders includes nearly 39,000 species work has been on Indian mygalomorphs, mainly the families in over 3600 genera in 110 families (Platnick, 2005: Version 6.0). Theraphosidae and Lycosidae (Gravely, 1915, 1921a,b, 1922, Tikader (1987) in his checklist of Indian spiders compiled a list 1931, 1935a,b). His studies in southern and northeastern India of 1067 species occurring in India. Much of his work was based revealed many new species to science, which are deposited at on published literature and post-independence collections of the Government Museum, Chennai and at the National Museum, the Zoological Survey of India expeditions to different regions. Kolkata. In the same year as Gravely’s first descriptions of His compilation is noteworthy since it provided spider workers spiders from the wild, Karam Narayan, Professor of Biology, St. in India and the neighbouring countries with an accessible John’s College, Agra, described seven new species and one checklist of Indian spiders. Further, Tikader also described subspecies of an ant-like spider (Attidae = Salticidae) from the quite a few species and thereby adding valuable information to Indian Museum Collection, Kolkata (Narayan, 1915). Another the wealth of Indian spider knowledge. After Tikader’s 1987 Indian, S. Dyal (1935) described 45 new species and compiled publication, much of the work carried out by Indian taxonomic notes on 76 species, all from Lahore, but since we arachnologists has been based on his work, including recent are restricting this checklist to the current political boundary of descriptions such as Bastawade (2002) based on Tikader’s India, Dyal’s spiders have been excluded from this list, although description of an allied species from Andaman Island. More many of them are likely to occur in India. Further studies recently, with an increase in spider taxonomy and the hard work confirming their presence on the Indian side is required. of Platnick and his group, the world checklist has provided a new dimension to our knowledge. Platnick's (2005) The World Major contributions to Indian arachnology were made by R.I. Spider Catalog has also provided good insights into Pocock and B.K. Tikader, who were responsible for bringing standardized approaches for understanding spider diversity spider studies to the notice of other researchers. R.I. Pocock, and taxonomy around the world. Although Platnick and his described 112 new species of spiders from India (Pocock, 1895, group are in the process of continuously revising the world 1899a,b, 1900a,b, 1901) before switching to studies of primate spider catalogue, it is up to regional and national spider taxonomy (Pocock, 1928). Many of Pocock’s species taxonomists / systematists to review and revise the existing descriptions have subsequently undergone taxonomic checklists. In this light we took up the task of compiling the revisions. His book in 1900 provided the first list of spiders, Indian spider checklist as part of a bigger task of compiling along with enumeration and new descriptions in British India, such a list for South Asia. We constantly refer to Tikader’s based on the spider specimens at the British Museum, London, work, and the changes shown in the current list are in reference which is widely referred by arachnologists of this region. to his 1987 publication.
