Araneae, Anapidae)
Proc. 16th Europ. ColI. Arachnol. 151-164 Siedlce, 10.03.1997 Egg sac structure and further biological observations in Comaroma simonii1 Bertkau (Araneae, Anapidae) Christian KROPF Natural History Museum Berne, Department oflnvertebrates, Bernastrasse 15, CH-3005 Berne, Switzerland. Key words: Araneae, Anapidae, Comaroma, behaviour, ecology, reproduction. ABSTRACT Specimens of Comaroma simonii Bertkau from Styria (Austria) were kept in the laboratory in order to investigate biological details. Egg sacs were built at the end of June and the beginning of July. They were white-coloured, round in shape with a diameter of 1.47 mm on the average (n = 5) and were attached to vertical surfaces. Each egg sac contained three eggs of pale yellow colour. Normally the egg sac is protected by a silken funnel ending in a tube that points toward the ground underneath. It is assumed that this functions as a means of protection against egg predators and parasites. Spiderlings hatched after 27 days; they most probably moulted twice before leaving the cocoon on the 35th day. They built webs closely resembling those of the adults. Juveniles and sub adults showed no sclerotization of the body and were rarely found in the natural.habitat. There, vertical and horizontal migrations probably occur as a means of avoiding wetness or drying out, respectively. The sex ratio of all collected specimens was 98 females to 54 males. C. simonii is regarded as a 'k-strategist' and an eurychronous species. INTRODUCTION The biology of Anapidae is insufficiently known. For example, data on egg sacs or juveniles are fragmentary (Hickman 1938, 1943; Platnick & Shadab 1978; Coddington 1986; Eberhard 1987). -

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. -

A Protocol for Online Documentation of Spider Biodiversity Inventories Applied to a Mexican Tropical Wet Forest (Araneae, Araneomorphae)

JAVIER SALGUEIRO- SEPÚLVEDA1 1Laboratorio de Aracnología, Facultad de Ciencias, Departamento de Biología Comparada, Universidad Nacional Autónoma de México, Circuito Exterior s/n, Colonia Copilco el Bajo. 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. -

Behavioral Ecology Symposium ’96: Cushing 165 MYRMECOMORPHY AND MYRMECOPHILY IN SPIDERS: A REVIEW PAULA E. CUSHING The College of Wooster Biology Department 931 College Street Wooster, Ohio 44691 ABSTRACT Myrmecomorphs are arthropods that have evolved a morphological resemblance to ants. Myrmecophiles are arthropods that live in or near ant nests and are considered true symbionts. The literature and natural history information about spider myrme- comorphs and myrmecophiles are reviewed. Myrmecomorphy in spiders is generally considered a type of Batesian mimicry in which spiders are gaining protection from predators through their resemblance to aggressive or unpalatable ants. Selection pressure from spider predators and eggsac parasites may trigger greater integration into ant colonies among myrmecophilic spiders. Key Words: Araneae, symbiont, ant-mimicry, ant-associates RESUMEN Los mirmecomorfos son artrópodos que han evolucionado desarrollando una seme- janza morfológica a las hormigas. Los Myrmecófilos son artrópodos que viven dentro o cerca de nidos de hormigas y se consideran verdaderos simbiontes. Ha sido evaluado la literatura e información de historia natural acerca de las arañas mirmecomorfas y mirmecófilas . El myrmecomorfismo en las arañas es generalmente considerado un tipo de mimetismo Batesiano en el cual las arañas están protegiéndose de sus depre- dadores a través de su semejanza con hormigas agresivas o no apetecibles. La presión de selección de los depredadores de arañas y de parásitos de su saco ovopositor pueden inducir una mayor integración de las arañas mirmecófílas hacia las colonias de hor- migas. Myrmecomorphs and myrmecophiles are arthropods that have evolved some level of association with ants. Myrmecomorphs were originally referred to as myrmecoids by Donisthorpe (1927) and are defined as arthropods that mimic ants morphologically and/or behaviorally. -

On Three Monotypic Nursery Web Spider Genera from Madagascar

CRUZ DA SILVA & PETRA SIERWALD Division of Insects, Field Museum of Natural History, 1400 S Lake Shore Drive, Chicago, IL, 60605, USA. E-mail: [email protected], [email protected] With 333 described species, the Pisauridae is a moderately species-rich spider family. The family is world wide in distribution and its members exhibit an exceptionally wide range of foraging and prey capture behavior, from web- based hunters, water surface hunters to ambusher hunters in the vegetation. While some pisaurid genera are diverse, boasting numerous species, such as Dolomedes with 96 described species, nearly half of pisaurid genera (22/48) are monotypic (Platnick 2013). Recent collecting and biodiversity research has uncovered several new species, especially from heretofore poorly collected regions in Africa (including Madagascar) and Asia (e.g. Jaeger 2011, Jocqué 1994). Initial steps have been undertaken to develop a phylogenetic framework for parts of the family, e.g., Sierwald 1987; Santos 2007. However, no phylogenetic analysis exists that includes a representatively wide range of genera. The clade Pisaurinae (see Sierwald 1997) appears to be well supported by morphological characters, while the relationships among non-pisaurine genera remain uncertain. -
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. -
