Zoogeography of Arachnida by Petar Beron Pdf

This volume merges all geographical and paleogeographical data on all groups of the arachnofauna. The book features topics such as the ecological factors, climate and other barriers that influence the distribution of arachnida. It also elaborates on the characteristics of the distribution such as arachnida at high altitude (e.g. Himalaya), in caves, in polar regions and highlights differences between the arachnofauna of e.g. Mediterranean regions vs Central Europe, West African vs Indomalayan and more. Furthermore, amongst other topics the volume also includes chapters on the systems of arachnida, fossil orders, dispersal and dispersion, endemics and relicts, regional arachnogeography, cave and high altitude arachnida.

A revision of the spider genus Selenops Latreille, 1819 (Arachnida, Araneae, Selenopidae) in North America, Central America and the Caribbean by Sarah C. Crews Pdf

The spider genus Selenops occurs in both the Old World and New World subtropics and tropics and contains nearly half of the species in the family Selenopidae. These spiders are extremely flattened dorsoventrally and are amongst the fast-est animals in the world. Despite the large size of some species, these aforementioned characteristics can make them difficult to detect. In this monograph the species from North America, Central America and Caribbean Islands (excluding Cuban endemics) are revised. In total, 21 new species are described and 6 species are synonymized. The males of S. bani and S. marcanoi, and the females of S. phaselus and S. geraldinae are described for the first time. Almost all species are redescribed, with new illustrations, including the internal female copulatory organs, most of which are illustrated for the first time. New distributional records and a key to species are also provided.

The velvet spiders: an atlas of the Eresidae (Arachnida, Araneae) by Jeremy A. Miller,Charles E. Griswold,Nikolaj Scharff,Milan ?ez??,Tam?s Sz?ts,Mohammad Marhabaie Pdf

The name velvet spider describes the dark and shiny appearance of members of the family Eresidae. Some species also have brightly-colored highlights, such as the red, white, and black ladybird spiders of Europe and North Asia. This family also includes some of the world?s most cooperative spider species. Social species can be very abundant in parts of tropical Africa and Asia with conspicuous colonies dotting the landscape. Social colonies may consist of hundreds of closely-related individuals that participate in dramatic mass attacks on prey and care for their young. The ecology of these social species is fascinating and has been the subject of several landmark scientific papers. By contrast, most kinds of velvet spider are rarely encountered. Most species keep well hidden or dig burrows and live underground. This monograph provides a generic-level review of Eresidae documented with collections of photographs, scanning electron micrographs, and illustrations. A key to the nine genera and other major lineages is provided. A new phylogeny of Eresidae based on molecular sequence data expands on a previously published analysis. Cybertaxonomic enhancements include an interactive map of the specimens used in the study explorable using Google Earth, specimen records uploaded to GBIF, and molecular sequence alignments and other data archived on Dryad. An EDIT Integrated Research grant provided principal funding for this project.

The spider family Selenopidae (Arachnida, Araneae) in Australasia and the Oriental Region by Sarah C. Crews,Mark S. Harvey Pdf

ÿThe Selenopidae are a family of medium to large spiders with extremely flattened bodies. They are exceptional in that both their running and striking speeds place them amongst the world?s fastest animals. They occur in all habitable continents but are most abundant in tropical and adjacent realms. Selenopid spiders are usually found under rocks or under tree bark, and have the ability to squeeze into tight crevices. The family currently comprises around 200 species in five genera. In this monograph, four new genera and 27 new species are described from Australia and the Oriental Region, bringing the world total to nine genera and over 230 species. Several species previously placed in Selenops are transferred to the new genera. The Australian fauna is found to be more diverse than previously documented with a total of 24 species, 23 of which are new. A key to the genera of Selenopidae is provided, as are keys to the species of the new genera Karaops and Makdiops.

The spider family Micropholcommatidae (Arachnida: Araneae: Araneoidea): a relimitation and revision at the generic level by Mihael G. Rix,Mark S. Harvey Pdf

The Micropholcommatidae are a family of tiny, distinctive araneoid spiders, known from southern-temperate habitats throughout Australasia and Chile. The greatest abundance of individuals and the largest diversity of taxa occur in the cool-temperate rainforests of south-eastern Australia and New Zealand, where micropholcommatid spiders can be very common within moss and leaf litter microhabitats. Although poorly studied biologically and largely neglected taxonomically, the Micropholcommatidae are a diverse lineage, with a significantÿ The monograph in this volume presents a complete generic-level revision of the spider family Micropholcommatidae. The phylogenetic position and internal phylogeny of the family are tested with two separate morphological cladistic analyses, the results of which inform a comprehensive generic-level classification. In total, 26 new species, 12 new genera, one new tribe and two new subfamilies are described, taking the total documented micropholcommatid fauna to 58 species. The distribution and Gondwanan biogeography of the family are also discussed, and natural history information is provided where known. Most importantly, the results of this paper present a taxonomic framework and a phylogenetic foundation for all future research on the Micropholcommatidae; a template by which new species can be described and existing species can be identified, and a valuable dataset for exploring phylogenetic hypotheses.

The Biology of Camel-Spiders by Fred Punzo Pdf

My initial interest in the Solifugae (camel-spiders) stems from an incident that occurred in the summer of 1986. I was studying the behavioral ecology of spider wasps of the genus Pepsis and their interactions with their large theraphosid (tarantula) spider hosts, in the Chihuahuan Desert near Big Bend National Park, Texas. I was monitoring a particular tarantula burrow one night when I noticed the resident female crawl up into the burrow entrance. Hoping to take some photographs of prey capture, I placed a cricket near the entrance and waited for the spider to pounce. Suddenly, out of the comer of my eye appeared a large, rapidly moving yellowish form which siezed the cricket and quickly ran off with it until it disappeared beneath a nearby mesquite bush. So suddenly and quickly had the sequence of events occurred, that I found myself momentarily startled. With the aid of a headlamp I soon located the intruder, a solifuge, who was already busy at work macerating the insect with its large chelicerae (jaws). When I attempted to nudge it with the edge of my forceps, it quickly moved to another location beneath the bush. When I repeated this maneuver, the solifuge dropped the cricket and lunged at the forceps, gripping them tightly in its jaws, refusing to release them until they were forcefully pulled away.
