THE SPIDER GENUS BILLIMA SIMON* by Hgngw W
THE SPIDER GENUS BILLIMA SIMON* By Hgngw W. LEVI NIuseum of Comparative Zoology, Harvard University Simon (I9O8) described the species Billima attrita which he placed in the subfamily Theridiosomatinae. Recently I noticed that Bonnet (959, P. 5o42) placed the genus in the subfamily Argio- pinae. _As I just revised the American species of the subfamily, an examination of the type specimen appeared in order. I would like. to. thank Prof. M. Vachon and M. Hubert ]?or the loan o,f the specimen from the NIusum National d'Histoire Na- turelle, Paris. Billima attrita is a theridiid. It does not belong in t'he family Araneidae ( Argiopidae) or to. the Theridiosomatidae as. it lacks a colulus, has only one tooth on the chelicerae, and the labium is not rebordered. All members of both the Araneidae and Theridiosomatidae ha.ve a large colulus, and usually have numerous teeth on the cheli- cerae and a rebordered labium. Billima attrita belongs to the genus T'heridion (Levi and Levi, I96Z). A description is presented here and the species is illustrated t?or the first time.

Abundance of Spiders and Insect Predators on Grapes in Central California
1999. The Journal of Arachnology 27:531-538 ABUNDANCE OF SPIDERS AND INSECT PREDATORS ON GRAPES IN CENTRAL CALIFORNIA Michael J. Costello!:Costello1: University of California Cooperative Extension, 1720 South Maple Ave., Fresno, California 93702 USA Kent M. Daane: Center for Biological Control, Division of Insect Biology, Department of Environmental Science, Policy and Management, University of California, Berkeley, California 94720 USA ABSTRACT We compared the abundance of spiders and predaceous insects in five central California vineyards. Spiders constituted 98.198.1%% of all predators collected. More than 90% of all spiders collected were from eight species of spiders, representing six families. Two theridiids (Theridion dilutum and T. melanurum) were the most abundant, followed by a miturgid (Cheiracanthium inclusum) and an agelinid (Hololena nedra). Predaceous insects comprised 1.6% of all predators collected, and were represented by six genera in five families. Nabis americoferis (Heteroptera, Nabidae) was the most common predaceous insect, with its densities highest late in the growing season. Chrysoperla camea,carnea, Chrysoperla comanche and Chrysopa oculata (Neuroptera, Chrysopidae) and Hippodamia convergens (Coleoptera, Coccinellidae) were most abundant early in the season. The dominance of spiders may be due to their more stable position in the vineyard predator community compared to predaceous insects. We also suggest that the low per?per centage of predaceous insects (e.g., lacewings) may reflect the lack of preferred prey (e.g., aphids) on grapevines.grape vines. Spiders are important predators in agroeagroe? ported population densities of the most cosystems (reviews in Nyfeller & Benz 1987; abundant spiders (Misumenops spp.) found on Nyfeller et al. -
Abundance and Community Composition of Arboreal Spiders: the Relative Importance of Habitat Structure
AN ABSTRACT OF THE THESIS OF Juraj Halaj for the degree of Doctor of Philosophy in Entomology presented on May 6, 1996. Title: Abundance and Community Composition of Arboreal Spiders: The Relative Importance of Habitat Structure. Prey Availability and Competition. Abstract approved: Redacted for Privacy _ John D. Lattin, Darrell W. Ross This work examined the importance of structural complexity of habitat, availability of prey, and competition with ants as factors influencing the abundance and community composition of arboreal spiders in western Oregon. In 1993, I compared the spider communities of several host-tree species which have different branch structure. I also assessed the importance of several habitat variables as predictors of spider abundance and diversity on and among individual tree species. The greatest abundance and species richness of spiders per 1-m-long branch tips were found on structurally more complex tree species, including Douglas-fir, Pseudotsuga menziesii (Mirbel) Franco and noble fir, Abies procera Rehder. Spider densities, species richness and diversity positively correlated with the amount of foliage, branch twigs and prey densities on individual tree species. The amount of branch twigs alone explained almost 70% of the variation in the total spider abundance across five tree species. In 1994, I experimentally tested the importance of needle density and branching complexity of Douglas-fir branches on the abundance and community structure of spiders and their potential prey organisms. This was accomplished by either removing needles, by thinning branches or by tying branches. Tying branches resulted in a significant increase in the abundance of spiders and their prey. Densities of spiders and their prey were reduced by removal of needles and thinning. -
Zur Taxonomie, Verbreitung Und Sexualbiologie Von Theridion Adrianopoli DRENSKY (Arachnida: Araneae, Theridiidae)
© Naturwiss.-med. Ver. Innsbruck; download unter www.biologiezentrum.at Ber. nat.-med. Verein Innsbruck Band 84 S. 133 - 148 Innsbruck, Okt. 1997 Zur Taxonomie, Verbreitung und Sexualbiologie von Theridion adrianopoli DRENSKY (Arachnida: Araneae, Theridiidae) Barbara KNOFLACH *) Taxonomy, Distribution and Sexual Biology of Theridion adrianopoli DRENSKY (Arachnida: Araneae, Theridiidae) Synopsis: Theridion adrianopoli DRENSKY, 1915, which was previously known only by the female and only from the type locality Edirne (European Turkey), is presented in both sexes from several localities in Greece, together with three new synonymies: Th. cretaense WUNDERLICH, 1995 (dÇ, from Crete), Th. do- donaeum BRIGNOLI, 1984 (d, from Epirus), Th. hauseri BR1GNOLI, 1984 (9, from Ikaria island). Appar- ently Th. adrianopoli is a widespread and common species in the southeastern Mediterranean, inhabiting sparse woodland. Its sexual biology corresponds with other Theridion-spedes, as it shows a high number of copulatory sequences (CS, n= 13-19) and sperm inductions (n= 12-18). Each CS except the last one is succeeded by a sperm induction and a period of quiescence (5-12 min). The entire copulation lasts 3.5-6 hours. Many inser- tion attempts are performed, the palps being inserted successfully only 7-32 times, 2 - 6 times per CS. Not all CS result in sperm transfer. The very first one is a pseudocopulation (sensu VAN HELSD1NGEN 1965,1983), and the last 6-9 sequences involve the attachment of a mating plug. 1. Einleitung: Theridion adrianopoli DRENSKY, 1915 wurde seit der nach dem Q erfolgten Erstbeschrei- gung nicht mehr gemeldet. DELTSHEV (1992) bildete den Typus erneut ab, kannte aber ebenfalls keine weiteren Funde. -

The pitfalls of exaggeration: molecular and morphological evidence suggests Kaliana is a synonym of Mesabolivar (Araneae: Pholcidae) JONAS J. ASTRIN1, BERNHARD MISOF & BERNHARD A. HUBER2 Zoologisches Forschungsmuseum Alexander Koenig, Adenauerallee 160, D-53113 Bonn, Germany. Corresponding author. E-mail: [email protected]; [email protected] Abstract When the Venezuelan genus Kaliana Huber, 2000 was described, it was based on a single male specimen that was mor- phologically unique among pholcid spiders, especially in its extremely exaggerated male genitalia. The morphology of the recently discovered female suggests a close relationship with Mesabolivar González-Sponga, 1998. Using molecular sequences (mitochondrial CO1, 16S, and nuclear 28S) of Kaliana yuruani Huber, 2000 and 53 other pholcid taxa (152 sequences, 19 of them sequenced in this study) in a Bayesian and a maximum parsimony approach, we show that Kaliana is not sister group of, but nested within the species-rich South American genus Mesabolivar. Therefore, we argue that Kaliana is a junior synonym of Mesabolivar (Mesabolivar yuruani, n. comb.). Complementing previous stud- ies on pholcid phylogeny, we also present evidence for a close relationship between Mesabolivar and Carapoia, support the synonymy of Anomalaia and Metagonia with molecular data, support the monophyly of 'ninetines' and question the recently postulated position of Priscula as nested within the New World clade. Key words: pholcid spiders, subfamily-level groups, Metagonia, Carapoia, Priscula, beta-taxonomy, phylogeny Introduction There seems to be a tendency for taxonomists to create new genera for highly ‗aberrant‘ species. For example, when the first spider species with directionally asymmetric male genitalia was discovered, a new genus was erected for it (Anomalaia González-Sponga, 1998). -

KNOFLACH & K. PFALLER Abstract: Comb-footed spiders - an introduction (Araneae, Theridiidae). Comb-footed spiders rep- resent a comprehensive, derived and successful orbicularian spider family. They fascinate by a wide spec- trum of morphological and biological traits. The present paper gives an overview on their morphology and behaviour, with emphasis on the European species. Key words: Theridiidae, morphological characterisation, behaviour. Einleitung 111 Einleitung Morphologische Charakterisierung... 115 Der Name Theridiidae geht auf das alt- Körpergröße 115 griechische Theridion zurück und bedeutet Färbung, Zeichnung 115 kleine Bestie. So wurde die Typusgattung Prosoma 117 auch als Wildspinne bezeichnet (MENGE Augen 123 1868: 164). Kugelspinnen (oder Hauben- Cheliceren 123 netzspinnen) faszinieren durch enorme Labium 123 Vielgestaltigkeit hinsichtlich Färbung, Ha- Sternum 123 bitus, Genitalmorphologie und Biologie. Weiblicher Palpus 123 Die deutschen Namen weisen auf das kugel- Beine 127 förmige Abdomen vieler Arten bzw. auf die Borstenkamm 127 Form des Schlupfwinkels hin (WlEHLE Stridulationsorgan 127 1937).

AAS 1999 Annual Meeting Abstracts Oral and Poster Presentations 1999 AAS Annual Meeting Univ. of the West Indies St. Augustine, Trinidad THERIDIID SYSTEMATICS: A PRELIMINARY MOLECULAR AND MORPHOLOGICAL PHYLOGENETIC ANALYSIS Ingi Agnarsson, Miquel A. Arnedo, Rosie Gillespie, Jonathan Coddington, & Gustavo Hormiga The family Theridiidae (cob-web spiders) is one of the largest spider families, comprising over 2000 described species in 73 genera and exhibiting extreme diversity in morphology, ecology and behavior. Theridiids are unique in including many cooperative or quasisocial species, a behavior otherwise very rare in arachnids. Theridiids include some very familiar species, such as the common house spider (Achaearanea tepidariorum) and the widow spiders (Latrodectus spp.). Despite their relatively high profile, systematic work on the family has so far been limited to the inclusion of a few of its members in family level phylogenetic analyses. We present the first cladistic analysis of a wide selection of theridiid genera based on molecular and morphological data. Apart from presenting a higher level phylogenetic hypothesis of theridiid interrelations, we address questions such as their sister relationship with nesticids, the monophyly and placement of the putative theridiid subfamily Hadrotarsinae, and the evolution of several morphological traits. CANNIBALISM AS A FACTOR REGULATING POPULATION DENSITY IN THE WOLF SPIDER PARDOSA MILVINA (ARANEAE, LYCOSIDAE) Robert Balfour, Sean E. Walker & Ann L. Rypstra Cannibalism has been suggested as a factor that can regulate population density in wolf spiders. We used a series of laboratory and field experiments to determine if cannibalism occurs in Pardosa milvina and if it is density dependent. Field collected Pardosa were paired in laboratory arenas in order to measure the level of aggression. -

Memòria presentada per Eva De Mas Castroverde per optar al grau de doctora en Ciències Biològiques El Director de tesi La Doctoranda Carles Ribera Almerje Eva De Mas Castroverde Profesor titular Universidad de Barcelona Llegenda dels Pireneus En temps del regnat de Túbal a Iberia, el pastor de tres caps Gerión, el més repulsiu de tots els monstres, li prengué el regne i la corona. La bella princesa Pyrene, filla de Túbal, besnéta de Nóe, aterrida, va anar a amagar-se a les altes muntanyes. Però Gerión, amb el propòsit d’esposar-la, la perseguí, i per fer-la sortir del bosc ordenà cremar les muntanyes. Les flames, creixent-se amb el vent, s’estenien per tota la serralada desfent tot el que trobaven al seu pas. Per les vessants de les muntanyes lliscaven ardents torrents de lava que socarrimaven tot el que tingués vida, estenent darrera seu un horrible llençol de mort. Els boscos cremaven, i ossos, teixons, porcs senglars i llops corrien aterrits. Els pobles s’inundaven de rius abrasadors i els núvols de fum negre tapaven el sol. Hércules, amant de Pyrene, va escoltar el crits de la princesa i, estenent els seus braços en aquell mar de foc, la prengué. Ella, abans de morir, tan sols tingué temps d’explicar-li els fets.
