The First Record of Family Segestriidae Simon, 1893 (Araneae: Dysderoidea) from Iran
Serket (2014) vol. 14(1): 15-18. The first record of family Segestriidae Simon, 1893 (Araneae: Dysderoidea) from Iran Alireza Zamani Department of Animal Biology, School of Biology and Center of Excellence in Phylogeny of Living Organisms in Iran, College of Science, University of Tehran, Tehran, Iran [email protected] Abstract The family Segestriidae Simon, 1893 and the species Segestria senoculata (Linnaeus, 1758) are recorded in Iran for the first time, based on a single female specimen. Keywords: Spiders, Segestriidae, Segestria senoculata, new record, Iran. Introduction Segestriidae Simon, 1893 is a small family of medium-sized, araneomorph, ecribellate, haplogyne spiders with three tarsal claws which are globally represented by 119 species in three genera (Platnick, 2014). These spiders are six-eyed, and are usually distinguishable by having their third pair of legs directed forwards. From taxonomic point of view, Segestriidae is closely related to Dysderidae, and are considered as a member of the superfamily Dysderoidea. The type genus, Segestria Latreille, 1804, is consisted of 18 species and one subspecies which are mostly distributed in the Palaearctic ecozone (Platnick, 2014). One of the more distributed species is Segestria senoculata (Linnaeus, 1758). This species, like most segestriids, occupies a wide variety of habitats; they prefer living in holes within walls and barks, or under stones, where they build a tubular retreat, with strong threads of silk radiating from the entrance (Roberts, 1995). So far, about 500 spider species of more than 38 families have been reported from Iran (based on our upcoming work on the renewed checklist and the history of studies), but no documentation of the family Segestriidae has been reported from Iran (Mozaffarian & Marusik, 2001; Ghavami, 2006; Kashefi et al., 2013). -
The Road Travelled by Australian Trapdoor Spiders
Discovered words and photo by Mark Harvey, WA Museum ustralia is home to many unique spiders with most species occurring Anowhere else on Earth. Many have their origins in the distant past, when Australia was part of Gondwana in the Mesozoic, ca. 180 million years ago. Australia, New Zealand, South America, Africa, Madagascar, Antarctica and the Indian sub-continent, plus a few small islands, once formed a massive southern supercontinent known as Gondwana that gradually fragmented from the Jurassic, ca. 180–160 million years ago. Evidence of the connection between these continental blocks can be found in the fossil record The road travelled by Australian of some plants and animals, but most strikingly in the presence of related groups trapdoor spiders of organisms in the modern biota. But back to spiders.

Arachnids (Excluding Acarina and Pseudoscorpionida) of the Wichita Mountains Wildlife Refuge, Oklahoma
OCCASIONAL PAPERS THE MUSEUM TEXAS TECH UNIVERSITY NUMBER 67 5 SEPTEMBER 1980 ARACHNIDS (EXCLUDING ACARINA AND PSEUDOSCORPIONIDA) OF THE WICHITA MOUNTAINS WILDLIFE REFUGE, OKLAHOMA JAMES C. COKENDOLPHER AND FRANK D. BRYCE The Wichita Mountains are located in eastern Greer, southern Kiowa, and northwestern Comanche counties in Oklahoma. Since their formation more than 300 million years ago, these rugged mountains have been fragmented and weathered, until today the highest peak (Mount Pinchot) stands only 756 meters above sea level (Tyler, 1977). The mountains are composed predominantly of granite and gabbro. Forests of oak, elm, and walnut border most waterways, while at elevations from 153 to 427 meters prair ies are the predominant vegetation type. A more detailed sum mary of the climatic and biotic features of the Wichitas has been presented by Blair and Hubbell (1938). A large tract of land in the eastern range of the Wichita Moun tains (now northeastern Comanche County) was set aside as the Wichita National Forest by President McKinley during 1901. In 1905, President Theodore Roosevelt created a game preserve on those lands managed by the Forest Service. Since 1935, this pre serve has been known as the Wichita Mountains Wildlife Refuge. Numerous papers on Oklahoma spiders have been published (Bailey and Chada, 1968; Bailey et al., 1968; Banks et al, 1932; Branson, 1958, 1959, 1966, 1968; Branson and Drew, 1972; Gro- thaus, 1968; Harrel, 1962, 1965; Horner, 1975; Rogers and Horner, 1977), but only a single, comprehensive work (Banks et al., 1932) exists covering all arachnid orders in the state.

Abundance and Community Composition of Arboreal Spiders: the Relative Importance of Habitat Structure
AN ABSTRACT OF THE THESIS OF Juraj Halaj for the degree of Doctor of Philosophy in Entomology presented on May 6, 1996. Title: Abundance and Community Composition of Arboreal Spiders: The Relative Importance of Habitat Structure. Prey Availability and Competition. Abstract approved: Redacted for Privacy _ John D. Lattin, Darrell W. Ross This work examined the importance of structural complexity of habitat, availability of prey, and competition with ants as factors influencing the abundance and community composition of arboreal spiders in western Oregon. In 1993, I compared the spider communities of several host-tree species which have different branch structure. I also assessed the importance of several habitat variables as predictors of spider abundance and diversity on and among individual tree species. The greatest abundance and species richness of spiders per 1-m-long branch tips were found on structurally more complex tree species, including Douglas-fir, Pseudotsuga menziesii (Mirbel) Franco and noble fir, Abies procera Rehder. Spider densities, species richness and diversity positively correlated with the amount of foliage, branch twigs and prey densities on individual tree species. The amount of branch twigs alone explained almost 70% of the variation in the total spider abundance across five tree species. In 1994, I experimentally tested the importance of needle density and branching complexity of Douglas-fir branches on the abundance and community structure of spiders and their potential prey organisms. This was accomplished by either removing needles, by thinning branches or by tying branches. Tying branches resulted in a significant increase in the abundance of spiders and their prey. Densities of spiders and their prey were reduced by removal of needles and thinning. -
A Summary List of Fossil Spiders
A summary list of fossil spiders compiled by Jason A. Dunlop (Berlin), David Penney (Manchester) & Denise Jekel (Berlin) Suggested citation: Dunlop, J. A., Penney, D. & Jekel, D. 2010. A summary list of fossil spiders. In Platnick, N. I. (ed.) The world spider catalog, version 10.5. American Museum of Natural History, online at http://research.amnh.org/entomology/spiders/catalog/index.html Last udated: 10.12.2009 INTRODUCTION Fossil spiders have not been fully cataloged since Bonnet’s Bibliographia Araneorum and are not included in the current Catalog. Since Bonnet’s time there has been considerable progress in our understanding of the spider fossil record and numerous new taxa have been described. As part of a larger project to catalog the diversity of fossil arachnids and their relatives, our aim here is to offer a summary list of the known fossil spiders in their current systematic position; as a first step towards the eventual goal of combining fossil and Recent data within a single arachnological resource. To integrate our data as smoothly as possible with standards used for living spiders, our list follows the names and sequence of families adopted in the Catalog. For this reason some of the family groupings proposed in Wunderlich’s (2004, 2008) monographs of amber and copal spiders are not reflected here, and we encourage the reader to consult these studies for details and alternative opinions. Extinct families have been inserted in the position which we hope best reflects their probable affinities. Genus and species names were compiled from established lists and cross-referenced against the primary literature. -

Species Delimitation and Phylogeography of Aphonopelma Hentzi (Araneae, Mygalomorphae, Theraphosidae): Cryptic Diversity in North American Tarantulas
Species Delimitation and Phylogeography of Aphonopelma hentzi (Araneae, Mygalomorphae, Theraphosidae): Cryptic Diversity in North American Tarantulas Chris A. Hamilton1*, Daniel R. Formanowicz2, Jason E. Bond1 1 Auburn University Museum of Natural History and Department of Biological Sciences, Auburn University, Auburn, Alabama, United States of America, 2 Department of Biology, The University of Texas at Arlington, Arlington, Texas, United States of America Abstract Background: The primary objective of this study is to reconstruct the phylogeny of the hentzi species group and sister species in the North American tarantula genus, Aphonopelma, using a set of mitochondrial DNA markers that include the animal ‘‘barcoding gene’’. An mtDNA genealogy is used to consider questions regarding species boundary delimitation and to evaluate timing of divergence to infer historical biogeographic events that played a role in shaping the present-day diversity and distribution. We aimed to identify potential refugial locations, directionality of range expansion, and test whether A. hentzi post-glacial expansion fit a predicted time frame. Methods and Findings: A Bayesian phylogenetic approach was used to analyze a 2051 base pair (bp) mtDNA data matrix comprising aligned fragments of the gene regions CO1 (1165 bp) and ND1-16S (886 bp). Multiple species delimitation techniques (DNA tree-based methods, a ‘‘barcode gap’’ using percent of pairwise sequence divergence (uncorrected p- distances), and the GMYC method) consistently recognized a number of divergent and genealogically exclusive groups. Conclusions: The use of numerous species delimitation methods, in concert, provide an effective approach to dissecting species boundaries in this spider group; as well they seem to provide strong evidence for a number of nominal, previously undiscovered, and cryptic species. -
