A Taxonomic Revision of the Orb Weaver Genus Acacesia (Araneae: Araneidae)
A TAXONOMIC REVISION OF THE ORB WEAVER GENUS ACACESIA (ARANEAE: ARANEIDAE) BY St3sAy GIt3Ec< ABSTRACT There are five species of Acacesia which range collectively from southern North America to Argentina. Two are previously known members of the genus, A. cornigera Petrunkevitch and A. hamata (Hentz). Three of these are new species: A. villalobosi and A. yacuiensis, from southern Brazil, and A. benigna from Bolivia and Peru. INTRODUCTION Acacesia is a genus of orb-weaving spiders common and endemic to the Americas, proposed by Simon in 1892. Hentz named the type species Epeira foliata in 1847. The genus con- tained the single species A. hamata until Petrunkevitch (1925) described A. cornigera. Subsequently published names, illustra- tions, and descriptions of new species of Acacesia have turned out to be synonyms of the two extant species (Chamberlin and Ivie 1936, Badcock 1932). Levi (1976) redescribed A. hamata in a revi- sion of Nearctic orb weaver genera, mentioning the Neotropical A. cornigera in passing. He hypothesized at the time that "there are three or four additional species of Acacesia, all Neotropical and all similar in appearance." The specimens I have examined for the current taxonomic revision corroborate this statement, and I expand the genus to include three new South American species. This study represents an addition to Levi's ongoing project of revising Neotropical orb weavers. I here report the results of my taxonomic project for which I examined and illustrated over 350 museum specimens. I describe factors I considered in delimiting new species such as their Harvard College, Harvard University, Cambridge, MA 02138 current address: Department of Entomology, Comstock Hall, Cornell University, Ithaca, NY 14853 Manuscript received 7 July 1993. -
SHORT COMMUNICATION Presence of Vaejovis Franckei in Epiphytic

Santa Cruz Xoxocotla´n, Oaxaca, Me´xico. E-mail: [email protected] Abstract. Reports of scorpions on epiphytic bromeliads in temperate forests are scarce. Here we present some ecological aspects of this animal-plant interaction in three different types of temperate forests (pine, pine-oak and oak forest) in Oaxaca, Mexico. From 2005 to 2007, we collected 373 bromeliads belonging to 10 species, and each plant was defoliated in search of scorpions. We found 35 individuals of Vaejovis franckei Sissom 1989 in 19 bromeliads: 22 specimens in Tillandsia carlos-hankii with 21% occupancy and an average abundance of 2.1 6 1.9 individuals/plant; 12 specimens in T. prodigiosa (10% occupancy, average abundance 5 1.6 6 0.6) and one specimen in T. calothyrsus (3% occupancy, average abundance 5 1 6 0.0). Pine-oak forest had 29 individuals; pine forest, 4 individuals; and oak forest, 2 individuals. Percentage of occupancy differed among localities, while average abundance remained the same. Vaejovis franckei preferred T. carlos- hankii and pine-oak forest, which was correlated with the percentage of occupancy but not with the average abundance.

Biota Neotrop. 11(1a): http://www.biotaneotropica.org. br/v11n1a/en/abstract?inventory+bn0381101a2011. Abstract: In this study we present a database of spiders described and registered from the Neotropical region between 1757 and 2008. Results are focused on the diversity of the group in the State of São Paulo, compared to other Brazilian states. Data was compiled from over 25,000 records, published in scientific papers dealing with Neotropical fauna. These records enabled the evaluation of the current distribution of the species, the definition of collection gaps and priority biomes, and even future areas of endemism for Brazil. A total of 875 species, distributed in 50 families, have been described from the State of São Paulo. -

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. -

Bromeliads As Biodiversity Amplifiers and Habitat Segregation of Spider Communities in a Neotropical Rainforest
2010. The Journal of Arachnology 38:270–279 Bromeliads as biodiversity amplifiers and habitat segregation of spider communities in a Neotropical rainforest Thiago Gonc¸alves-Souza1, Antonio D. Brescovit2, Denise de C. Rossa-Feres1,andGustavo Q. Romero1,3: 1Departamento de Zoologia e Botaˆnica, IBILCE, Universidade Estadual Paulista, UNESP, Rua Cristo´va˜o Colombo 2265, CEP 15054- 000, Sa˜o Jose´ do Rio Preto, SP, Brazil; 2Instituto Butanta˜, Laborato´rio de Artro´podes Pec¸onhentos, Avenida Vital Brazil 1500, CEP 05503-900, Sa˜o Paulo, SP, Brazil Abstract. Although bromeliads can be important in the organization of invertebrate communities in Neotropical forests, few studies support this assumption. Bromeliads possess a three-dimensional architecture and rosette grouped leaves that provide associated animals with a good place for foraging, reproduction and egg laying, as well as shelter against desiccation and natural enemies. We collected spiders from an area of the Atlantic Rainforest, southeastern Brazil, through manual inspection in bromeliads, beating trays in herbaceous+shrubby vegetation and pitfall traps in the soil, to test if: 1) species subsets that make up the Neotropical forest spider community are compartmentalized into different habitat types (i.e., bromeliads, vegetation and ground), and 2) bromeliads are important elements that structure spider communities because they generate different patterns of abundance distributions and species composition, and thus amplify spider beta diversity. Subsets of spider species were compartmentalized into three habitat types. The presence of bromeliads represented 41% of the increase in total spider richness, and contributed most to explaining the high beta diversity values among habitats. Patterns of abundance distribution of the spider community differed among habitats. -

SYMBIOSES BETWEEN INSECTS AND SPIDERS: AN ASSOCIATION BETWEEN LEPIDOPTERAN LARVAE AND THE SOCIAL SPIDER ANELOSIMUS EXIMIUS (ARANEAE: THERIDIIDAE)* BY MICHAEL H. ROBINSON S mithsonian Tropical Research Institute P.O. Box 2072, Balboa, Canal Zone, Panama INTRODUCTION There are many instances of relationships between insects and spiders that are not simply relationships between predators and prey. Bristowe (1941) cites numerous examples either from his own extensive experience or from a broad review of the diverse litera- ture. Moths have been reported to associate with spiders' webs both as adults and larvae. Thus Pocock (1903) reported a case of commensalism between the gregarious spider Stegodyphus sp. (Eri- sidae) and the moth Batrachedra stegodyphobius Walsingham. The unnamed species of Stegodyphus from South Africa had small lepi- dopteran larvae crawling about within the communal web. These fed upon "the carcases of the flies or other insects which, with in- finite labour and patience, the spiders hauled up as near their nest as possible Pocock states that pupation occurred within the nest (= web) and that, after emergence, adult moths moved about the web walking, leaping and fluttering. Reportedly the moths did not get caught in the sticky (cribellate)silk "being gifted apparently, like the spiders themselves, with some safeguard against the sticki- ness of the threads, which proved so fatal to other insects" (1903: 169). Brach (1977) reports that the webs of Anelosimus studiosus, in Florida are shared by a host of other arthropods including py- ralid "webworms." He comments that the relationship between these other arthropods and the Anelosimus is not clear, but that the majority "are found in the periphery of senescent webs and may be physically isolated from contact with colony members by their own silken retreats" (1977:155). -

Smithsonian Institution, Washington, DC 20560 Herbert W. Levi Museum of Comparative Zoology, Harvard University, Cambridge, Massachusetts 02138 KEY WORDS: taxonomy, phytogeny, cladistics, biology, diversity INTRODUCTION In the last 15 years understanding of the higher systematics of Araneae has changed greatly. Large classical superfamilies and families have turned out to be poly- or paraphyletic; posited relationships were often based on sym- plesiomorphies. In this brief review we summarize current taxonomic and phylogenetic knowledge and suggest where future efforts might profitably be concentrated. We lack space to discuss fully all the clades mentioned, and the cited numbers of described taxa are only approximate. Other aspects of spider biology have been summarized by Barth (7), Eberhard (47), Jackson & Parks (72), Nentwig (105), Nyffeler & Benz (106), Riechert & Lockley (134), Shear (149) and Turnbull (160).

Spiders are among the most diverse groups on earth. Among these taxa, spiders are exceptional for their complete dependence on predation as a trophic strategy. In contrast, the diversity of insects and mites may result from their diversity in dietary strategies•notably phytophagy and parasitism (104).
