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 sting of the Aculeata or stinging wasps is a modifed ovipositor; its function (killing or paralyzing prey, defense against predators) and the associated anatomical changes are apomorphic for Aculeata. The change in the purpose of the ovipositor/sting from being primarily an egg laying device to being primarily a weapon has resulted in modifcation of its handling that is supported by specifc morphological adaptations. Here, we focus on the sheaths of the sting (3rd valvulae = gonoplacs) in Aculeata, which do not penetrate and envenom the prey but are responsible for cleaning the ovipositor proper and protecting it from damage, identifcation of the substrate for stinging, and, in some taxa, contain glands that produce alarm pheromones. -
Does Argentine Ant Invasion Conserve Colouring Variation of Myrmecomorphic Jumping Spider?

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. -

EENY493 Giant Whip Scorpion Mastigoproctus giganteus giganteus (Lucas, 1835) (Arachnida: Thelyphonida (=Uropygi): Thelyphonidae) 1 William H. Kern and Ralph E. Mitchell2 Introduction shrimp can deliver to an unsuspecting finger during sorting of the shrimp from the by-catch. The only whip scorpion found in the United States is the giant whip scorpion, Mastigoproctus giganteus giganteus (Lucas). The giant whip scorpion is also known as the ‘vinegaroon’ or ‘grampus’ in some local regions where they occur. To encounter a giant whip scorpion for the first time can be an alarming experience! What seems like a miniature monster from a horror movie is really a fairly benign creature. While called a scorpion, this arachnid has neither the venom-filled stinger found in scorpions nor the venomous bite found in some spiders. One very distinct and curious feature of whip scorpions is its long thin caudal appendage, which is directly related to their common name “whip-scorpion.” The common name ‘vinegaroon’ is related to their ability to give off a spray of concentrated (85%) acetic acid from the base of the whip-like tail. This produces that tell-tale vinegar-like scent. The common name ‘grampus’ may be related to the mantis shrimp, also called the grampus. The mantis shrimp Figure 1. The giant whip scorpion or ‘vingaroon’, Mastigoproctus is a marine crustacean that can deliver a painful wound giganteus giganteus (Lucas). Credits: R.

The Case of Embrik Strand (Arachnida: Araneae) 22-29 Arachnologische Mitteilungen / Arachnology Letters 59: 22-29 Karlsruhe, April 2020

The case of Embrik Strand (Arachnida: Araneae) 22-29 Arachnologische Mitteilungen / Arachnology Letters 59: 22-29 Karlsruhe, April 2020 How to deal with destroyed type material? The case of Embrik Strand (Arachnida: Araneae) Wolfgang Nentwig, Theo Blick, Daniel Gloor, Peter Jäger & Christian Kropf doi: 10.30963/aramit5904 Abstract. When the museums of Lübeck, Stuttgart, Tübingen and partly of Wiesbaden were destroyed during World War II between 1942 and 1945, also all or parts of their type material were destroyed, among them types from spider species described by Embrik Strand bet- ween 1906 and 1917. He did not illustrate type material from 181 species and one subspecies and described them only in an insufficient manner. These species were never recollected during more than 110 years and no additional taxonomically relevant information was published in the arachnological literature. It is impossible to recognize them, so we declare these 181 species here as nomina dubia. Four of these species belong to monotypic genera, two of them to a ditypic genus described by Strand in the context of the mentioned species descriptions. Consequently, without including valid species, the five genera Carteroniella Strand, 1907, Eurypelmella Strand, 1907, Theumella Strand, 1906, Thianella Strand, 1907 and Tmeticides Strand, 1907 are here also declared as nomina dubia. Palystes modificus minor Strand, 1906 is a junior synonym of P. -
Molecular Basis of the Remarkable Species Selectivity of an Insecticidal
www.nature.com/scientificreports OPEN Molecular basis of the remarkable species selectivity of an insecticidal sodium channel toxin from the Received: 03 February 2016 Accepted: 20 June 2016 African spider Augacephalus Published: 07 July 2016 ezendami Volker Herzig1,*, Maria Ikonomopoulou1,*,†, Jennifer J. Smith1,*, Sławomir Dziemborowicz2, John Gilchrist3, Lucia Kuhn-Nentwig4, Fernanda Oliveira Rezende5, Luciano Andrade Moreira5, Graham M. Nicholson2, Frank Bosmans3 & Glenn F. King1 The inexorable decline in the armament of registered chemical insecticides has stimulated research into environmentally-friendly alternatives. Insecticidal spider-venom peptides are promising candidates for bioinsecticide development but it is challenging to find peptides that are specific for targeted pests. In the present study, we isolated an insecticidal peptide (Ae1a) from venom of the African spider Augacephalus ezendami (family Theraphosidae). Injection of Ae1a into sheep blowflies (Lucilia cuprina) induced rapid but reversible paralysis. In striking contrast, Ae1a was lethal to closely related fruit flies (Drosophila melanogaster) but induced no adverse effects in the recalcitrant lepidopteran pest Helicoverpa armigera. Electrophysiological experiments revealed that Ae1a potently inhibits the voltage-gated sodium channel BgNaV1 from the German cockroach Blattella germanica by shifting the threshold for channel activation to more depolarized potentials. In contrast, Ae1a failed to significantly affect sodium currents in dorsal unpaired median neurons from the American cockroachPeriplaneta americana. We show that Ae1a interacts with the domain II voltage sensor and that sensitivity to the toxin is conferred by natural sequence variations in the S1–S2 loop of domain II. The phyletic specificity of Ae1a provides crucial information for development of sodium channel insecticides that target key insect pests without harming beneficial species. -
The Phylogeny of Fossil Whip Spiders Russell J
Garwood et al. BMC Evolutionary Biology (2017) 17:105 DOI 10.1186/s12862-017-0931-1 RESEARCH ARTICLE Open Access The phylogeny of fossil whip spiders Russell J. Garwood1,2*, Jason A. Dunlop3, Brian J. Knecht4 and Thomas A. Hegna4 Abstract Background: Arachnids are a highly successful group of land-dwelling arthropods. They are major contributors to modern terrestrial ecosystems, and have a deep evolutionary history. Whip spiders (Arachnida, Amblypygi), are one of the smaller arachnid orders with ca. 190 living species. Here we restudy one of the oldest fossil representatives of the group, Graeophonus anglicus Pocock, 1911 from the Late Carboniferous (Duckmantian, ca. 315 Ma) British Middle Coal Measures of the West Midlands, UK. Using X-ray microtomography, our principal aim was to resolve details of the limbs and mouthparts which would allow us to test whether this fossil belongs in the extant, relict family Paracharontidae; represented today by a single, blind species Paracharon caecus Hansen, 1921. Results: Tomography reveals several novel and significant character states for G. anglicus; most notably in the chelicerae, pedipalps and walking legs. These allowed it to be scored into a phylogenetic analysis together with the recently described Paracharonopsis cambayensis Engel & Grimaldi, 2014 from the Eocene (ca. 52 Ma) Cambay amber, and Kronocharon prendinii Engel & Grimaldi, 2014 from Cretaceous (ca. 99 Ma) Burmese amber. We recovered relationships of the form ((Graeophonus (Paracharonopsis + Paracharon)) + (Charinus (Stygophrynus (Kronocharon (Charon (Musicodamon + Paraphrynus)))))). This tree largely reflects Peter Weygoldt’s 1996 classification with its basic split into Paleoamblypygi and Euamblypygi lineages; we were able to score several of his characters for the first time in fossils. -

Behavioral Ecology Symposium ’96: Cushing 165 MYRMECOMORPHY AND MYRMECOPHILY IN SPIDERS: A REVIEW PAULA E. CUSHING The College of Wooster Biology Department 931 College Street Wooster, Ohio 44691 ABSTRACT Myrmecomorphs are arthropods that have evolved a morphological resemblance to ants. Myrmecophiles are arthropods that live in or near ant nests and are considered true symbionts. The literature and natural history information about spider myrme- comorphs and myrmecophiles are reviewed. Myrmecomorphy in spiders is generally considered a type of Batesian mimicry in which spiders are gaining protection from predators through their resemblance to aggressive or unpalatable ants. Selection pressure from spider predators and eggsac parasites may trigger greater integration into ant colonies among myrmecophilic spiders. Key Words: Araneae, symbiont, ant-mimicry, ant-associates RESUMEN Los mirmecomorfos son artrópodos que han evolucionado desarrollando una seme- janza morfológica a las hormigas. Los Myrmecófilos son artrópodos que viven dentro o cerca de nidos de hormigas y se consideran verdaderos simbiontes. Ha sido evaluado la literatura e información de historia natural acerca de las arañas mirmecomorfas y mirmecófilas . El myrmecomorfismo en las arañas es generalmente considerado un tipo de mimetismo Batesiano en el cual las arañas están protegiéndose de sus depre- dadores a través de su semejanza con hormigas agresivas o no apetecibles. La presión de selección de los depredadores de arañas y de parásitos de su saco ovopositor pueden inducir una mayor integración de las arañas mirmecófílas hacia las colonias de hor- migas. Myrmecomorphs and myrmecophiles are arthropods that have evolved some level of association with ants. Myrmecomorphs were originally referred to as myrmecoids by Donisthorpe (1927) and are defined as arthropods that mimic ants morphologically and/or behaviorally. -
