Indian Journal of Arachnology 5 (1-2): 130-142 ISSN 2278-1587 (Online) REDESCRIPTION OF FOUR WOLF-SPIDERS (ARANEAE: LYCOSIDAE) FROM INDIA Tian Lu1, Lu-Yu Wang1, Priyanka Hadole2 and Zhi-Sheng Zhang1* 1Key Laboratory of Eco-environments in Three Gorges Reservoir Region (Ministry of Education), School of Life Science, Southwest University, Chongqing 400715, China 2Department of Zoology, SGB Amravati University, Amravati 444601, India *Corresponding author: [email protected] ABSTRACT Four Lycosidae species from India are redescribed: Arctosa mulani (Dyal, 1935), Lycosa poonaensis Tikader & Malhotra, 1980, Pardosa sutherlandi (Gravely, 1924) and Wadicosa fidelis (O. Pickard-Cambridge, 1872). Digital pictures, SEM photos and illustrations are provided. Keywords: Wolf spiders, India, photos, SEM, illustration. INTRODUCTION The wolf spider family Lycosidae is a large group with 123 genera and 2397 species from all the continents except the Antarctica (World Spider Catalog, 2016). The Indian Subcontinent has great diversity of spiders, including more than one hundred lycosids. Four species of Lycosidae were confirmed and are redescribed in this paper: Arctosa mulani (Dyal, 1935), Lycosa poonaensis Tikader & Malhotra, 1980, Pardosa sutherlandi (Gravely, 1924) and Wadicosa fidelis(O. Pickard -Cambridge, 1872). MATERIAL AND METHODS Genitalias were photographed, scanned and illustrated, using Leica M205A stereo microscope and Zeiss EVO LS10 SEM. Habitus digitalized using Canon 7D Camera (alive) and under M205A (preserved). We examined the specimens from Amravati and the Melghat Tiger Reserve. All specimens examined here are deposited in the School of Life Sciences, Southwest University, Chongqing, China (SWUC). TAXONOMY Family Lycosidae Sundevall, 1833 Arctosa mulani (Dyal, 1935) (Figures1A–H, 2A–D, 3A–D, 12 A–B) Pardosa mulani Dyal, 1935: 146, pl. 13, figs. 45–46 (♀). Arctosa mulani Tikader & Malhotra, 1980: 373, figs. 247–251 (♂♀). Diagnosis. This species is similar to Arctosa tridentata Chen & Song, 1999 (Chen & Song, 1999: 139, figs 4–7), but differs from the latter by the presence of a strong terminal apophysis, wide conductor and strong median apophysis (Figures 1C–F, 2A–D, 3A–B).

Mahavidyalaya, Kavathe Mahankal, Sangli. *Former Professor and Head, Department of Zoology, Shivaji University, Kolhapur. ABSTRACT Diversity of spiders from Radhanagari Wildlife Sanctuary, Chandoli Na- tional Park and Koyna Wildlife Sanctuary in Western Ghats is studied for the first time. A total of 247 species belonging to 119 genera and 28 families are recorded from the study area during 2010-2012 with a dominance of Araneid, Salticid and Lycosid spiders. Key words: Spider diversity, Western Ghats INTRODUCTION Spiders comprise one of the largest (5-6th) orders of animals. The spider fauna of India has never been studied in its entirety despite of contributions by many arachnologists since Stoliczka (1869). The pioneering contribution on the taxonomy of Indian spiders is that of European arachnologist Stoliczka (1869). Review of available literature reveals that the earliest contribution by Blackwall (1867); Karsch (1873); Simon (1887); Thorell (1895) and Pocock (1900) were the pioneer workers of Indian spiders. They described many species from India. Tikader (1980, 1982), Tikader, and Malhotra (1980a,b) described spiders from India. Tikader (1980) compiled a book on Thomisid spiders of India, comprising two subfamilies, 25 genera and 115 species. Of these, 23 species were new to science. Descriptions, illustrations and distributions of all species were given. Keys to the subfamilies, genera, and species were provided. Tikader and Biswas (1981) studied 15 families, 47 genera and 99 species from Calcutta and surrounding areas with illustrations and descriptions.

  • The Complete Mitochondrial Genome of Endemic Giant Tarantula
    www.nature.com/scientificreports OPEN The Complete Mitochondrial Genome of endemic giant tarantula, Lyrognathus crotalus (Araneae: Theraphosidae) and comparative analysis Vikas Kumar, Kaomud Tyagi *, Rajasree Chakraborty, Priya Prasad, Shantanu Kundu, Inderjeet Tyagi & Kailash Chandra The complete mitochondrial genome of Lyrognathus crotalus is sequenced, annotated and compared with other spider mitogenomes. It is 13,865 bp long and featured by 22 transfer RNA genes (tRNAs), and two ribosomal RNA genes (rRNAs), 13 protein-coding genes (PCGs), and a control region (CR). Most of the PCGs used ATN start codon except cox3, and nad4 with TTG. Comparative studies indicated the use of TTG, TTA, TTT, GTG, CTG, CTA as start codons by few PCGs. Most of the tRNAs were truncated and do not fold into the typical cloverleaf structure. Further, the motif (CATATA) was detected in CR of nine species including L. crotalus. The gene arrangement of L. crotalus compared with ancestral arthropod showed the transposition of fve tRNAs and one tandem duplication random loss (TDRL) event. Five plesiomophic gene blocks (A-E) were identifed, of which, four (A, B, D, E) retained in all taxa except family Salticidae. However, block C was retained in Mygalomorphae and two families of Araneomorphae (Hypochilidae and Pholcidae). Out of 146 derived gene boundaries in all taxa, 15 synapomorphic gene boundaries were identifed. TreeREx analysis also revealed the transposition of trnI, which makes three derived boundaries and congruent with the result of the gene boundary mapping. Maximum likelihood and Bayesian inference showed similar topologies and congruent with morphology, and previously reported multi-gene phylogeny. However, the Gene-Order based phylogeny showed sister relationship of L.

A B S T R A C T Spiders are distributed all over the world and have occupied almost all ecological habitats, except open air and the open sea. They are extremely common representatives of most terrestrial communities and have a profound impact on the insect population of the ecosystem. Their presence and density are directly related to the structure of the habitat. In the present study, the four different natural habitats of the upper northern Rajasthan, namely- Semi-arid Grassland, Scrubland, Open forest land, and Riparian land were studied for spider assemblage. According to the structure of the habitat, the dominance of some specific species was observed. The Neoscona mukerjei was found a prevalent species in 3 habitats out of 4 studied habitats.

Received: 1 Oct. 2017, Revised: 10 Dec. 2017, Accepted: 21 Dec. 2017. Published online: 1 Jan. 2018. Abstract: In the present study, monthly and seasonal fluctuations of densities of terrestrial spiders were recorded in six different sites at Qena Governorate during the period of one year (February, 2012 - January, 2013). The study revealed the occurrence of 1247 specimens belonging to 14 families and including 23 species of order Araneae. Family Salticidae recorded the highest number during the whole period of study (278 specimens) while family Agelenidae recorded the lowest number in the same period of study (4 specimens). It was observed that the maximal number was collected from Thanatus albini (199 specimens), while Halodromus barbarae was the least species in number since only 2 specimens were collected. The densities of the recorded spiders varied seasonally and the general seasonal peak was recorded during autumn (363 specimens), while the lowest density was observed during winter (215 specimens). Regarding the sex ratio of the collected spiders from all sites, it was clear that there were 213 adult male specimens, whereas the adult females were represented by 440 specimens.

  • Zootaxa, Draposa, a New Wolf Spider Genus from South and Southeast
    Zootaxa 2637: 31–54 (2010) ISSN 1175-5326 (print edition) www.mapress.com/zootaxa/ Article ZOOTAXA Copyright © 2010 · Magnolia Press ISSN 1175-5334 (online edition) Draposa, a new wolf spider genus from South and Southeast Asia (Araneae: Lycosidae) TORBJÖRN KRONESTEDT Department of Entomology, Swedish Museum of Natural History, Box 50007, SE-104 05 Stockholm, Sweden. E-mail: [email protected] Abstract Draposa gen. nov. is proposed for eight wolf spider species from the Indomalayan Region, all of which were previously placed in the genus Pardosa: Draposa atropalpis (Gravely,1924) comb. nov., D. lyrivulva (Bösenberg & Strand, 1906) comb. nov. (=Pardosa leucopalpis Gravely, 1924 syn. nov.), D. nicobarica (Thorell, 1891) comb. nov., D. oakleyi (Gravely, 1924) comb. nov., D. porpaensis (U. A. Gajbe, 2004) comb. nov., D. subhadrae (Patel & Reddy, 1993) comb. nov., D. tenasserimensis (Thorell, 1895) comb. nov., and D. zhanjiangensis (Yin, Wang, Peng & Xie, 1995) comb. nov. Species of Draposa share synapomorphies in the copulatory organs, inter alia a complex subpaleal sclerite in the terminal part of the male bulbus. The presence of D. lyrivulva in Japan is put in doubt and the species should be excluded from the list of spiders in that country. Draposa nicobarica (type species) and D. tenasserimensis are redescribed and illustrated for the first time from the type material. Draposa atropalpis is redescribed from material from India and Sri Lanka, D. lyrivulva and D. subhadrae (first record outside India) from material collected in Sri Lanka and D. oakleyi from material from India and Bangladesh. Key words: Taxonomy, Pardosa, Indomalayan region Introduction The world-wide spider family Lycosidae Sundevall, 1833 (wolf spiders) comprises 2367 currently recognised species, of which 526 species (with 22 additional intraspecific taxa) are assigned to the genus Pardosa C.

M. Sureshan1, Kailash Chandra2 1Zoological Survey of India, Western Ghat Regional Centre, Kozkhikore - 673006, India 2Zoological Survey of India, M- Block, New Alipore, Kolkata - 700053, India *E-mail address: [email protected] ABSTRACT Annotated checklist of Lycosoidea so far recorded from different states and union territories of India reveals a total of 251 species under 38 genera belonging five families. The review cleared that diversity of lycosoid spider fauna is maximum in West Bengal followed by Madhya Pradesh, Maharashtra, Tamil Nadu and they are not distributed maximally in the states and union territories within Biodiversity hotspots. This fauna is distributed all over the country. There is nearly 69.35% endemism (in context of India). Keywords: Distribution; Lycosoidea; India; State; Union Territories; Annotated; checklist 1. INTRODUCTION Spiders, composing the order Araneae Clerck, 1757 is the largest group among arachnids and separated into two suborders: Mesothelae Pocock, 1892 (segmented spiders) World Scientific News 47(2) (2016) 298-317 and Opisthothelae Pocock, 1892 (includes all other spiders). Later one is further divided into two infraorders: Mygalomorphae Pocock, 1892 (ancient' spiders) and Araneomorphae Smith, 1902 (modern' spiders include the vast majority of spiders) (Coddington, 2005; WSC, 2015). Araneomorphae composed of 99 families and most of them can be divided into at least six clades and 11 super-families, though some are still unplaced in that system (Zhang, 2011).
