Parson Spiders
Colorado Arthropod of Interest Parson Spiders Scientific Name: Herpyllus species Order: Araneae (Spiders) Family: Gnaphosidae (Ground Spiders) Identification and Descriptive Features: The parson spiders are moderately large spiders (female 6.5-13mm; male 4.5-6.5mm) with overall black color. A broken white or silvery stripe prominently marks the back of the abdomen. (This marking is reminiscent of the old style neck band cravat formerly worn by parsons and others of the ministry.) A wide shiny band of reflective silvery hairs occurs on the cephalothorax. The legs that are brown, banded with black and relatively long; parson spiders are fast runners. Distribution in Colorado: Four species are known from Colorado: Herpyllus bubulcus, H. ecclesiasticus (eastern parson spider), H. Figures 1, 2. Top and side views of two hesperolus, and H. propinquus (western parson different spieces of parson spider (Herpyllus spider). At least one Herpyllus species can likely spp.).

Life History and Habits: Parson spiders can be common invaders of buildings in late summer and early fall. Indoors they may be found crawling on walls and they can move quickly, often running in a zig-zag pattern. They do not breed indoors. The parson spiders are active at night and in twilight hours. During the day they seek cover provided by loose bark, boards or other sheltering sites and often form a silken retreat within which they rest. Life history is poorly known. Eggs of at least some species are produced in late summer and early fall. -
The Placement of the Spider Genus Periegops and the Phylogeny of Scytodoidea (Araneae: Araneomorphae)
Zootaxa 3312: 1–44 (2012) ISSN 1175-5326 (print edition) www.mapress.com/zootaxa/ Article ZOOTAXA Copyright © 2012 · Magnolia Press ISSN 1175-5334 (online edition) The placement of the spider genus Periegops and the phylogeny of Scytodoidea (Araneae: Araneomorphae) FACUNDO M. LABARQUE1 & MARTÍN J. RAMÍREZ1 1Museo Argentino de Ciencias Naturales “Bernardino Rivadavia”, Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET), Av. Ángel Gallardo 470, C1405DJR, Buenos Aires, Argentina. [email protected] / [email protected] Abstract The relationships of Scytodoidea, including the families Drymusidae, Periegopidae, Scytodidae and Sicariidae, have been con- tentious for a long time. Here we present a reviewed phylogenetic analysis of scytodoid spiders, emphasizing Periegops, the only genus in the family Periegopidae. In our analysis the Scytodoidea are united by the fusion of the third abdominal entapo- physes into a median lobe, the presence of female palpal femoral thorns and associated cheliceral stridulatory ridges, a mem- branous lobe on the cheliceral promargin, and the loss of minor ampullate gland spigots. A basal split within Scytodoidea defines two monophyletic groups: Sicariidae and a group formed by Scytodidae as the sister group of Periegopidae plus Dry- musidae, all united by having bipectinate prolateral claws on tarsi I–II, one major ampullate spigot accompanied by a nubbin, and the posterior median spinnerets with a mesal field of spicules. Periegops is the sister group of Drymusidae, united by the regain of promarginal cheliceral teeth and a triangular cheliceral lamina, which is continuous with the paturon margin. Key words: Drymusa, Drymusidae, Haplogyne, morphology, Scytodes, Stedocys, Scytodidae, Sicariidae, Sicarius, Loxosceles Introduction The family Periegopidae currently comprises only the genus Periegops, with two species: the type species Perie- gops suteri (Urquhart) from the Banks Peninsula on the South Island of New Zealand (Vink 2006), and Periegops australia Forster, from southeastern Queensland (Forster 1995). -

C. P. 04510. Del. Coyoacán, Ciudad de México, México. E-mail: [email protected] 2Corresponding author Abstract Spider community inventories have relatively well-established standardized collecting protocols. Such protocols set rules for the orderly acquisition of samples to estimate community parameters and to establish comparisons between areas. These methods have been tested worldwide, providing useful data for inventory planning and optimal sampling allocation efforts. The taxonomic counterpart of biodiversity inventories has received considerably less attention. Species lists and their relative abundances are the only link between the community parameters resulting from a biotic inventory and the biology of the species that live there. However, this connection is lost or speculative at best for species only partially identified (e. g., to genus but not to species). This link is particularly important for diverse tropical regions were many taxa are undescribed or little known such as spiders. One approach to this problem has been the development of biodiversity inventory websites that document the morphology of the species with digital images organized as standard views. -

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. -
Life-History Constraints in Inaccurate Batesian Myrmecomorphic Spiders (Araneae: Corinnidae, Gnaphosidae)
Eur. J. Entomol. 108: 255–260, 2011 http://www.eje.cz/scripts/viewabstract.php?abstract=1614 ISSN 1210-5759 (print), 1802-8829 (online) Life-history constraints in inaccurate Batesian myrmecomorphic spiders (Araneae: Corinnidae, Gnaphosidae) STANO PEKÁR and MARTIN JARAB Department of Botany and Zoology, Faculty of Science, Masaryk University, Kotlá Ĝská 2, 611 37 Brno, Czech Republic; e-mail: [email protected] Key words. Formicidae, prey, trophic niche, clutch size, copulation, courtship Abstract. Accurate Batesian mimicry is known to impose constraints on some traits of the mimic, such as foraging or reproductive behaviour. It is not known whether life-history traits of inaccurate Batesian mimics are constrained as well. We studied selected life- history traits of three spider species, Liophrurillus flavitarsis, Phrurolithus festivus (both Corinnidae), and Micaria sociabilis (Gna- phosidae), that are inaccurate mimics of ants. Namely, we were interested in how myrmecomorphy (ant-like resemblance) constrains their circadian activity, trophic niche and reproductive behaviour. The spiders were found to have diurnal activity like their models, whereas their close relatives have nocturnal activity. The three mimics do not catch ants, nor do they use food resources of ants, but catch various tiny invertebrates that occur in the vicinity of their models. Their trophic niche seems to be constrained by occurrence among ants. Absence of courtship and long lasting copulation, in a position that does not provide protective resemblance, do not seem to be constrained by mimicry in the three species. Comparative analysis of fecundity in mimetic and non-mimetic spiders showed that clutch size is also not constrained. Unlike in accurate mimics, life-history traits of inaccurate myrmecomorphs appear not to be constrained. -
