A Checklist of the Non -Acarine Arachnids
Original Research A CHECKLIST OF THE NON -A C A RINE A R A CHNIDS (CHELICER A T A : AR A CHNID A ) OF THE DE HOOP NA TURE RESERVE , WESTERN CA PE PROVINCE , SOUTH AFRIC A Authors: ABSTRACT Charles R. Haddad1 As part of the South African National Survey of Arachnida (SANSA) in conserved areas, arachnids Ansie S. Dippenaar- were collected in the De Hoop Nature Reserve in the Western Cape Province, South Africa. The Schoeman2 survey was carried out between 1999 and 2007, and consisted of five intensive surveys between Affiliations: two and 12 days in duration. Arachnids were sampled in five broad habitat types, namely fynbos, 1Department of Zoology & wetlands, i.e. De Hoop Vlei, Eucalyptus plantations at Potberg and Cupido’s Kraal, coastal dunes Entomology University of near Koppie Alleen and the intertidal zone at Koppie Alleen. A total of 274 species representing the Free State, five orders, 65 families and 191 determined genera were collected, of which spiders (Araneae) South Africa were the dominant taxon (252 spp., 174 genera, 53 families). The most species rich families collected were the Salticidae (32 spp.), Thomisidae (26 spp.), Gnaphosidae (21 spp.), Araneidae (18 2 Biosystematics: spp.), Theridiidae (16 spp.) and Corinnidae (15 spp.).

Mutual mate-choice behavior is also pronounced in this species. Evarcha culicivora also identifies opposite-sex conspecific Here we show that, when E. culicivora feeds indirectly on blood, it individuals (i.e., potential mates) not only by sight but also by acquires a diet-related odor that makes it more attractive to the odor (7, 17). Here we consider whether there is a link between opposite sex. The mate-choice decisions of the adults of both sexes this predator’s unusual diet and its mate-choice decisions, our were investigated in a series of experiments based on comparing how hypothesis being that, by feeding on bloodcarrying mosquitoes, long the test spider remained close to the odor of one source spider E. culicivora acquires an odor (or ‘perfume’) that is preferred by on one day and to the odor of a different source spider on the potential mates. -
Untangling Taxonomy: a DNA Barcode Reference Library for Canadian Spiders
Molecular Ecology Resources (2016) 16, 325–341 doi: 10.1111/1755-0998.12444 Untangling taxonomy: a DNA barcode reference library for Canadian spiders GERGIN A. BLAGOEV, JEREMY R. DEWAARD, SUJEEVAN RATNASINGHAM, STEPHANIE L. DEWAARD, LIUQIONG LU, JAMES ROBERTSON, ANGELA C. TELFER and PAUL D. N. HEBERT Biodiversity Institute of Ontario, University of Guelph, Guelph, ON, Canada Abstract Approximately 1460 species of spiders have been reported from Canada, 3% of the global fauna. This study provides a DNA barcode reference library for 1018 of these species based upon the analysis of more than 30 000 specimens. The sequence results show a clear barcode gap in most cases with a mean intraspecific divergence of 0.78% vs. a min- imum nearest-neighbour (NN) distance averaging 7.85%. The sequences were assigned to 1359 Barcode index num- bers (BINs) with 1344 of these BINs composed of specimens belonging to a single currently recognized species. There was a perfect correspondence between BIN membership and a known species in 795 cases, while another 197 species were assigned to two or more BINs (556 in total). A few other species (26) were involved in BIN merges or in a combination of merges and splits. There was only a weak relationship between the number of specimens analysed for a species and its BIN count. However, three species were clear outliers with their specimens being placed in 11– 22 BINs. Although all BIN splits need further study to clarify the taxonomic status of the entities involved, DNA bar- codes discriminated 98% of the 1018 species. The present survey conservatively revealed 16 species new to science, 52 species new to Canada and major range extensions for 426 species. -

Previous research using computer animation and lures made from dead 19 20 prey has demonstrated that the East African salticid Evarcha culicivora Wesolowska & 20 21AQ3 Jackson (Araneae: Salticidae) feeds indirectly on vertebrate blood by actively choosing 21 22 blood-carrying female mosquitoes as prey, and also that it singles out mosquitoes of 22 23AQ4 the genus Anopheles (Diptera: Culicidae) by preference. Here, we demonstrate that 23 24 E. culicivora’s preference is expressed when the species is tested with living prey 24 25 and that it is unique to E. culicivora. As an alternative hypothesis, we considered 25 26 26 the possibility that the preference for blood-fed female anopheline mosquitoes might 27 27 28 be widespread in East African salticids. -

Does Argentine Ant Invasion Conserve Colouring Variation of Myrmecomorphic Jumping Spider?
Open Journal of Animal Sciences, 2014, 4, 144-151 Published Online June 2014 in SciRes. http://www.scirp.org/journal/ojas http://dx.doi.org/10.4236/ojas.2014.43019 Argentine Ant Affects Ant-Mimetic Arthropods: Does Argentine Ant Invasion Conserve Colouring Variation of Myrmecomorphic Jumping Spider? Yoshifumi Touyama1, Fuminori Ito2 1Niho, Minami-ku, Hiroshima City, Japan 2Laboratory of Entomology, Faculty of Agriculture, Kagawa University, Ikenobe, Japan Email: [email protected] Received 23 April 2014; revised 3 June 2014; accepted 22 June 2014 Copyright © 2014 by authors and Scientific Research Publishing Inc. This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Argentine ant invasion changed colour-polymorphic composition of ant-mimetic jumping spider Myrmarachne in southwestern Japan. In Argentine ant-free sites, most of Myrmarachne exhibited all-blackish colouration. In Argentine ant-infested sites, on the other hand, blackish morph de- creased, and bicoloured (i.e. partly bright-coloured) morphs increased in dominance. Invasive Argentine ant drives away native blackish ants. Disappearance of blackish model ants supposedly led to malfunction of Batesian mimicry of Myrmarachne. Keywords Batesian Mimicry, Biological Invasion, Linepithema humile, Myrmecomorphy, Myrmarachne, Polymorphism 1. Introduction It has attracted attention of biologists that many arthropods morphologically and/or behaviorally resemble ants [1]-[4]. Resemblance of non-ant arthropods to aggressive and/or unpalatable ants is called myrmecomorphy (ant-mimicry). Especially, spider myrmecomorphy has been described through many literatures [5]-[9]. Myr- mecomorphy is considered to be an example of Batesian mimicry gaining protection from predators. -

Spiders of the Hawaiian Islands: Catalog and Bibliography1
Pacific Insects 6 (4) : 665-687 December 30, 1964 SPIDERS OF THE HAWAIIAN ISLANDS: CATALOG AND BIBLIOGRAPHY1 By Theodore W. Suman BISHOP MUSEUM, HONOLULU, HAWAII Abstract: This paper contains a systematic list of species, and the literature references, of the spiders occurring in the Hawaiian Islands. The species total 149 of which 17 are record ed here for the first time. This paper lists the records and literature of the spiders in the Hawaiian Islands. The islands included are Kure, Midway, Laysan, French Frigate Shoal, Kauai, Oahu, Molokai, Lanai, Maui and Hawaii. The only major work dealing with the spiders in the Hawaiian Is. was published 60 years ago in " Fauna Hawaiiensis " by Simon (1900 & 1904). All of the endemic spiders known today, except Pseudanapis aloha Forster, are described in that work which also in cludes a listing of several introduced species. The spider collection available to Simon re presented only a small part of the entire Hawaiian fauna. In all probability, the endemic species are only partly known. Since the appearance of Simon's work, there have been many new records and lists of introduced spiders. The known Hawaiian spider fauna now totals 149 species and 4 subspecies belonging to 21 families and 66 genera. Of this total, 82 species (5596) are believed to be endemic and belong to 10 families and 27 genera including 7 endemic genera. The introduced spe cies total 65 (44^). Two unidentified species placed in indigenous genera comprise the remaining \%. Seventeen species are recorded here for the first time. In the catalog section of this paper, families, genera and species are listed alphabetical ly for convenience. -
Distribution of Spiders in Coastal Grey Dunes

The knowledge of dispersal evolution, motivation, its effect on metapopulation dynamics and species distribution at multiple scales is poorly understood and many questions remain unsolved or require empirical verification. In this thesis we contribute to the knowledge of dispersal, by studying both ecological and evolutionary aspects of spider dispersal in fragmented grey dunes. Studies were performed at the individual, population and assemblage level and indicate that behavioural traits narrowly linked to dispersal, con- siderably show [adaptive] variation in function of habitat quality and geometry. Dispersal also determines spider distribution patterns and metapopulation dynamics. Consequently, our results stress the need to integrate knowledge on behavioural ecology within the study of ecological landscapes. / Promotor: Prof. Dr. Eckhart Kuijken [Ghent University & Institute of Nature Dries Bonte Conservation] Co-promotor: Prf.

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.
