Crab Spiders Impact Floral-Signal Evolution Indirectly Through Removal
ARTICLE DOI: 10.1038/s41467-018-03792-x OPEN Crab spiders impact floral-signal evolution indirectly through removal of florivores Anina C. Knauer1, Moe Bakhtiari1,2 & Florian P. Schiestl1 The puzzling diversity of flowers is primarily shaped by selection and evolutionary change caused by the plant’s interaction with animals. The contribution of individual animal species to net selection, however, may vary depending on the network of interacting organisms. Here 1234567890():,; we document that in the buckler mustard, Biscutella laevigata, the crab spider Thomisus onustus reduces bee visits to flowers but also benefits plants by feeding on florivores. Uninfested plants experience a trade-off between pollinator and spider attraction as both bees and crab spiders are attracted by the floral volatile β-ocimene. This trade-off is reduced by the induced emission of β-ocimene after florivore infestation, which is stronger in plant populations where crab spiders are present than where they are absent, suggesting that plants are locally adapted to the presence of crab spiders. Our study demonstrates the context-dependence of selection and shows how crab spiders impact on floral evolution. 1 Department of Systematic and Evolutionary Botany, University of Zurich, Zollikerstrasse 107, 8008 Zurich, Switzerland. 2Present address: Institute of Biology, University of Neuchatel, Rue Emile-Argand 11, 2000 Neuchatel, Switzerland.

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. -
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. -

A Paper on Cretaceous Fossil Spiders from Myanmar and a Paper on Extant Spiders from Portugal (Arachnida: Araneae)
A PAPER ON CRETACEOUS FOSSIL BEITR. ARANEOL., 14 (2021) Joerg Wunderlich & (2021) Patrick Müller SPIDERS FROM MYANMAR AND A PAPER 14 ON EXTANT SPIDERS FROM PORTUGAL (ARACHNIDA: ARANEAE) A PAPER ON CRETACEOUS FOSSIL BEITR. ARANEOL., 14 (2021) SPIDERS FROM MYANMAR AND A BEITR. ARANEOL., PAPER ON EXTANT SPIDERS FROM Joerg Wunderlich (ed.) PORTUGAL (ARACHNIDA: ARANEAE) In this paper I (JW) try to round off the “trinity of fossil spider faunas” of three vanished worlds: of the Dominican, Baltic and Burmese (Kachin) ambers (from ca. 22, 45 and 100 (!) million years ago), which I treated in about a dozen volumes concerning the most diverse group of predatory animals of this planet, the spiders (Araneae). We treat in short the cannibalism of few Cretaceous spiders and provide notes on their orb webs. The focus of this study is the diverse fauna of the higher strata which is preserved in Burmese (Kachin) amber. Probably as the most IMPORTANT GENERAL RESULTS I found the Mid Cretaceous Burmese spider fauna to be at least as diverse as the fauna of today but composed by quite different groups and – in contrast to most groups of insects - by numerous (more than 60 %) extinct families of which apparently not a single genus survived. I identified and described ca. 300 species (55 families) of spiders in Burmese (Kachin) amber and estimate that probably more than three thousand spider species lived 100 million years ago in this ancient forest which was a tropical rain forest. What will be the number of spider species (and other animals) that survives the next 100 years in the endangered rain forest of today in Myanmar? A second IMPORTANT GENERAL RESULT: probably during the last 60-70 million years ancient spider groups of the “Middle age of the Earth” (the Mesozoicum) were largely displaced by derived members of the Orb weavers like the well- known Garden Spider (as well as other members of the superfamily Araneoidea) and by spiders like Jumping Spiders, House Spiders and Wolf Spiders (members of the “RTA-clade”) which are very diverse and frequent today. -

BENJAMIN* Department of Integrative Biology, Section of Conservation Biology (NLU), University of Basel, St. Johanns-Vorstadt 10, CH-4056 Basel, Switzerland Received July 2003; accepted for publication February 2004 The subfamily Ballinae is revised. To test its monophyly, 41 morphological characters, including the first phyloge- netic use of scale morphology in Salticidae, were scored for 16 taxa (1 outgroup and 15 ingroup). Parsimony analysis of these data supports monophyly based on five unambiguous synapomorphies. The paper provides new diagnoses, descriptions of new genera, species, and a key to the genera. At present, Ballinae comprises 13 nominal genera, three of them new: Afromarengo, Ballus, Colaxes, Cynapes, Indomarengo, Leikung, Marengo, Philates and Sadies. Copocrossa, Mantisatta, Pachyballus and Padilla are tentatively included in the subfamily. Nine new species are described and illustrated: Colaxes horton, C. wanlessi, Philates szutsi, P. thaleri, P. zschokkei, Indomarengo chandra, I. -

A total of 55 species belonging to 36 genera and 13 families are sampled. Newly recorded taxa include four genera and 11 species of Araneidae, six genera of Araneidae, each represented by single species. The species recorded under Tylorida Simon and Tetragnatha Latreille of Tetragnathidae and Camaricus Thorell and Thomisus Walckenaer of Thomisidae are found to be new from the state. Also, three oxyopids and one miagrammopid are new. So far, Linyphiidae, Pisauridae, Sparassidae and Theridiidae were unknown from the state. Out of 55 species, 13 are endemic to India and thus exhibiting a high endemicity (23.6%). A family key of the State Fauna is provided along with relevant images of the newly recorded species.

Australian Native Bees Avoid Their Spider Predators
by responding to the same floral signals as these honeybees do (Heiling & Herberstein 2004; Heiling et al. 2004). Fur- thermore, it manipulates visual floral signals. While Euro- pean crab spiders appear camouflaged on flowers (Chittka 2001; The´ry & Casas 2002), T. spectabilis produces a Predator–prey coevolution: strong colour contrast in the UV range of the light spec- trum, attracting honeybees (Heiling et al. 2003). This is Australian native bees in line with empirical data showing that bees are attracted to strongly contrasting marks on flowers (Lunau et al. avoid their spider 1996). predators European honeybees did not coevolve with T. spectabilis but were introduced to Australia ca. 200 years ago. By * contrast, native Australian bees that are also captured by A. M. Heiling and M. E. Herberstein T. spectabilis coevolved with this species.
