ZooKeys 870: 77–100. https://doi.org/10.3897/zookeys.870.35971 Abstract The current paper expands knowledge of two Chinese cave spider species originally described in the genus Maymena Gertsch, 1960: M. paquini Miller, Griswold & Yin, 2009 and M. kehen Miller, Griswold & Yin, 2009. With the exception of these two species, the genus Maymena is endemic to the western hemisphere, and new evidence presented here supports the creation of a new genus for the Chinese species, which we name Yamaneta gen. nov. The male of Y. kehen is described for the first time. Detailed illustrations of the habitus, male palps and epigyne are provided for these two species, as well as descriptions of their webs. -

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. -

ABSTRAK Kebanyakan spesies labah-labah di Malaysia dianggap tidak berbahaya kepada manusia dan kes gigitan labah-labah jarang dilaporkan. Ini adalah disebabkan oleh kesan dari gigitan yang tidak serius dan mangsa tidak mendapatkan rawatan di hospital. Sehingga kini, hanya terdapat beberapa kes gigitan labah-labah yang didokumentasikan dari Malaysia. Di sini, kami melaporkan gejala gigitan, kaedah perawatan dan hasil perawatan dua pesakit yang digigit labah-labah pemburu ‘Hitam & Emas’ dari genus Thelcticopis di Malaysia yang masih belum dinamakan spesisnya. Kes pertama melibatkan seorang lelaki berusia 42 tahun yang telah digigit di hujung jari tengahnya, menyebabkan kesakitan dan bengkak setempat. Beliau dirawat secara simtomatik dan pulih tanpa sebarang komplikasi. Kes kedua melibatkan seorang wanita berusia 57 tahun, yang telah digigit pada jari kelingking, menyebabkan kesakitan berdenyut dan kebengkakan progresif. Dia dirawat secara simtomatik dan dibenarkan pulang selepas 24 jam di wad perubatan. Walau bagaimanapun, beliau mendapat sakit di leher dan sendi terutamanya pinggul dan lutut. Beliau telah dirawat dengan ubat tahan sakit dan semua gejala sembuh dalam tempoh dua hari. -

Three New Species of the Oonopid Spider Genus Ischnothyreus (Araneae: Oonopidae) from Tioman Island (Malaysia)
Zootaxa 3161: 37–47 (2012) ISSN 1175-5326 (print edition) www.mapress.com/zootaxa/ Article ZOOTAXA Copyright © 2012 · Magnolia Press ISSN 1175-5334 (online edition) Three new species of the oonopid spider genus Ischnothyreus (Araneae: Oonopidae) from Tioman Island (Malaysia) YVONNE KRANZ-BALTENSPERGER Natural History Museum, Bernastrasse 15, CH-3005 Bern, Switzerland. E-mail: [email protected] Abstract Three new species of the genus Ischnothyreus (I. tioman, I. tekek and I. namo) are described from Tioman Island off the eastern coast of Peninsular Malaysia. Two of the described species show peculiar cheliceral modifications that are dis- cussed with respect to similar structures found in other families. Key words: taxonomy, systematics, morphology, Asia Introduction With currently 755 described species in 83 genera (Platnick 2011), goblin spiders (Oonopidae) are an extremely diverse spider family. Most of them are ground-dwellers and live in litter or under bark, but some species are also found in the tree canopy (Fannes et al. 2008). They are small (0.5–4.0 mm), haplogyne, usually six-eyed spiders, and are most diverse in the tropical and subtropical regions of the world (Jocqué & Dippenaar-Schoeman 2006). The genus Ischnothyreus, established by Simon in 1893, currently comprises 41 species. Occurring worldwide, the genus is most abundant in the Oriental region (Platnick 2011). Recently, 17 new species were reported from Borneo (Kranz-Baltensperger 2011). The genus is also present in Australia (Edward & Harvey 2009). Males of Ischnothyreus have strongly sclerotized palps and modified endites, the females can be recognized by the winding genital tube. In this contribution three new species of Ischnothyreus are described from Tioman Island, a small island close to mainland Malaysia (Fig. -
Araneae (Spider) Photos
Araneae (Spider) Photos Araneae (Spiders) About Information on: Spider Photos of Links to WWW Spiders Spiders of North America Relationships Spider Groups Spider Resources -- An Identification Manual About Spiders As in the other arachnid orders, appendage specialization is very important in the evolution of spiders. In spiders the five pairs of appendages of the prosoma (one of the two main body sections) that follow the chelicerae are the pedipalps followed by four pairs of walking legs. The pedipalps are modified to serve as mating organs by mature male spiders. These modifications are often very complicated and differences in their structure are important characteristics used by araneologists in the classification of spiders. Pedipalps in female spiders are structurally much simpler and are used for sensing, manipulating food and sometimes in locomotion. It is relatively easy to tell mature or nearly mature males from female spiders (at least in most groups) by looking at the pedipalps -- in females they look like functional but small legs while in males the ends tend to be enlarged, often greatly so. In young spiders these differences are not evident. There are also appendages on the opisthosoma (the rear body section, the one with no walking legs) the best known being the spinnerets. In the first spiders there were four pairs of spinnerets. Living spiders may have four e.g., (liphistiomorph spiders) or three pairs (e.g., mygalomorph and ecribellate araneomorphs) or three paris of spinnerets and a silk spinning plate called a cribellum (the earliest and many extant araneomorph spiders). Spinnerets' history as appendages is suggested in part by their being projections away from the opisthosoma and the fact that they may retain muscles for movement Much of the success of spiders traces directly to their extensive use of silk and poison. -

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). Diversity, Paleontology, Descriptive Work, Importance The order Araneae ranks seventh in global diversity after the five largest insect orders (Coleoptera, Hymenoptera, Lepidoptera, Diptera, Hemiptera) and Acari among the arachnids (111) in terms of species described or an- *The US government has the right to retain a nonexclusive, royalty free license in and to any copyright covering this paper. 565 566 CODDINGTON & LEVI ticipated. 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). -

PLATNICK Division of Invertebrate Zoology, American Museum of Natural History, Central Park West at 79th Street, New York NY 10024 USA. E-mail: [email protected] In a recent review of the interrelationships of goblin spiders (the family Oonopidae), Platnick et al. (2012) presented a new subfamily-level classification of the family, replacing older arrangements that included at least one paraphyletic group. That analysis was based heavily on new evidence obtained, by an international consortium of researchers, through scanning electron microscopy of the tarsal organs, tiny chemoreceptors found near the tips of the legs and pedipalps. The tarsal organ data supplied new information supporting the monophyly of the family, as well as characters relevant to understanding relationships among its genera (the family currently includes over 1000 species in over 85 genera; see Platnick, 2012). These data also supplied an example of a kind of character variation that creates problems with the conventional application of clustering algorithms to matrices. Most oonopids show a pattern of 3-3-2-2 raised receptors on legs I–IV, respectively. However, members of two genera seem to have a pattern of 4-4-3-3 receptors instead, and members of at least one other genus probably have a 2-2-1-1 pattern.
