A New Species of Melloina (Araneae: Paratropididae) from Venezuela
ZOOLOGIA 30 (1): 101–106, February, 2013 http://dx.doi.org/10.1590/S1984-46702013000100013 A new species of Melloina (Araneae: Paratropididae) from Venezuela Rogério Bertani Laboratório Especial de Ecologia e Evolução, Instituto Butantan. Avenida Vital Brazil 1500, 05503-900 São Paulo, SP, Brazil. E-mail: [email protected]; [email protected] ABSTRACT. A new species of Melloina Brignoli, 1985, Melloina santuario sp. nov., is described from a cave in Venezuela. This is the third species described in this rarely sampled genus, and the first species known from both male and female. The male of M. santuario sp. nov. is distinguished by a longer embolus and fewer number of spines on the anterior tarsi. Females and immatures are distinguished by having fewer numbers of labial cuspules. The description of a new species from male and female samples increases our knowledge about Melloina. This added knowledge is important to the under- standing of mygalomorph relationships, mainly in the Theraphosoidina, as Melloina is a basal genus within the Paratropididae. KEY WORDS.

Sexual Selection Research on Spiders: Progress and Biases
Biol. Rev. (2005), 80, pp. 363–385. f Cambridge Philosophical Society 363 doi:10.1017/S1464793104006700 Printed in the United Kingdom Sexual selection research on spiders: progress and biases Bernhard A. Huber* Zoological Research Institute and Museum Alexander Koenig, Adenauerallee 160, 53113 Bonn, Germany (Received 7 June 2004; revised 25 November 2004; accepted 29 November 2004) ABSTRACT The renaissance of interest in sexual selection during the last decades has fuelled an extraordinary increase of scientific papers on the subject in spiders. Research has focused both on the process of sexual selection itself, for example on the signals and various modalities involved, and on the patterns, that is the outcome of mate choice and competition depending on certain parameters. Sexual selection has most clearly been demonstrated in cases involving visual and acoustical signals but most spiders are myopic and mute, relying rather on vibrations, chemical and tactile stimuli. This review argues that research has been biased towards modalities that are relatively easily accessible to the human observer. Circumstantial and comparative evidence indicates that sexual selection working via substrate-borne vibrations and tactile as well as chemical stimuli may be common and widespread in spiders. Pattern-oriented research has focused on several phenomena for which spiders offer excellent model objects, like sexual size dimorphism, nuptial feeding, sexual cannibalism, and sperm competition. The accumulating evidence argues for a highly complex set of explanations for seemingly uniform patterns like size dimorphism and sexual cannibalism. Sexual selection appears involved as well as natural selection and mechanisms that are adaptive in other contexts only. Sperm competition has resulted in a plethora of morpho- logical and behavioural adaptations, and simplistic models like those linking reproductive morphology with behaviour and sperm priority patterns in a straightforward way are being replaced by complex models involving an array of parameters. -
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. -

Note on Suspected Brown Recluse Spiders (Araneae: Sicariidae) in South Carolina
Faculty Research Note Note on Suspected Brown Recluse Spiders (Araneae: Sicariidae) in South Carolina Robert J. Wolff* South University, 9 Science Court, Columbia, SC 29203 The general public believes that brown recluse spiders (Loxosceles Filistatidae (Kukulcania hibernalis) 22 specimens reclusa) are widespread where they live and that these spiders are Lycosidae 21 (3 in one package, 5 in another) frequent causes of bites resulting in dermonecrosis. Research over the Pholcidae 17 past twenty years shows these reports to be unfounded. Vetter (2005) Miturgidae 8 examined 1,773 specimens sent in from across the U.S. as brown recluse Theridiidae 8 spiders and no specimens were found from areas outside the species Agelenidae 7 range, with the exception of a specimen from California. Araneidae 6 Clubionidae 6 The reported range of the brown recluse spider includes all or major Thomisidae 6 portions of Arkansas, Oklahoma, Texas, Louisiana, Alabama, Tennessee, Gnaphosidae 4 Kentucky, Illinois, Missouri and Kansas. Minor portions of the brown Corinnidae 3 recluse range were previously reported in Iowa, Indiana, Ohio, New Philodromidae 3 Mexico, North Carolina, Georgia, and South Carolina. The most recent Amaurobiidae 1 map (Vetter, 2015) does not include South Carolina, and only the far Pisauridae 1 western tip of North Carolina and northwestern corner of Georgia. Scytodidae (Scytodes thoracica) 1 Unidentifiable 4 Schuman and Caldwell (1991) found that South Carolina physicians reported treating 478 cases of brown recluse spider envenomations in 1990 alone. This seems like a very high number, unfortunately all or No brown recluses were identified from the specimens obtained in this almost all of these are probably not brown recluse spider bites. -
Panama and Costa Rica*
NEW SPECIES OF GRAMMONOTA (ARANEAE, LINYPHIIDAE) FROM PANAMA AND COSTA RICA* BY ARTHUR IV[. CHICKERING Museum of Comparative Zoology Numerous species of the genus Grammonota Emerton, I882, have been recognized trom North and Central America as far south as Costa Rica. Two species of this genus were reported from Costa Rica by Bishop and Crosby in 1932. Kraus (955) did not report this genus from E1 Salvador, and it has not been reported from Panama as far as I have. been able to determine. Many specimens belonging to this genus have appeared in my collections from Panama during the. past forty years and the present seems to be a convenient time to put these on record. The frequency with which members of this genus have appeared in my collections from Panama indicates, I believe, the need for more careful collecting throughout the Neo- tropical region. Grants GB-ISOI and GB-5oI3 from the National Science Founda- tion have turnished aid for several collecting trips in Central Amer- ica, the West Indies and Florida together with my continued research in the Museum of Comparative Zoology, Harvard University, for nearly five and one half year.s. As I have so frequently done in the past, I am again acknowledging the very gracious help and encour- agement received from members of the staff of the Museum of Com- parative Zoology extending over a period of many years. Genus Grammonota Emerton, 1882 Grammonota tabuna sp. nov. Figures I- IO Holotype. The male holotype is from Gatun, Panama Canal Zone, January 30, 1958.

Chapter 8 HEMOLYMPH AND HEMOCYTES OF TARANTULA SPIDERS: PHYSIOLOGICAL ROLES AND POTENTIAL AS SOURCES OF BIOACTIVE MOLECULES Tatiana Soares, Thiago H. Napoleão, Felipe R. B. Ferreira and Patrícia M. G. Paiva∗ Departamento de Bioquímica, Centro de Ciências Biológicas, Universidade Federal de Pernambuco, Cidade Universitária, Recife, Pernambuco, Brazil ABSTRACT Arachnids compose the most important and numerous group of chelicerates and include spiders, scorpions, mites and ticks. Some arachnids have a worldwide distribution and can live for more than two decades. This is in part due to their efficient defense system, with an innate immunity that acts as a first line of protection against bacterial, fungal and viral pathogens. The adaptive success of the spiders stimulates the study of their defense mechanisms at cellular and molecular levels with both biological and biotechnological purposes. The hemocytes (plasmatocytes, cyanocytes, granulocytes, prohemocytes, and leberidocytes) of spiders are responsible for phagocytosis, nodulation, and encapsulation of pathogens as well as produce substances that mediate humoral mechanisms such as antimicrobial peptides and factors involved in the coagulation of hemolymph and melanization of microorganisms.
