This book was released on 2012 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Neotropical spider genus Neoxyphinus Birabén, 1953, is revised, comprising 10 species found from the West Indies to northern Argentina. The genus is characterized by a unique combination of characters, which include the presence of a set of low tubercles or large spikes on the posterior surface of carapace; male endites with an apical, retrolateral excavation bearing a subapical toothlike apophysis; palpal bulb strongly inflated; embolus compact, S-shaped, with large, round ejaculatory opening; epigynal atrium large, with angular lateral corners. The large, round ejaculatory duct may be a synapomorphy of the genus. The genus Hawkeswoodoonops Makhan and Ezzatpanah, 2011, is synonymized with Neoxyphinus and the two species included in that genus are considered as nomina dubia. The monotypic genus Decuana Dumitrescu and Georgescu, 1987, is also synonymized with Neoxyphinus and its type species, D. hispida Dumitrescu and Georgescu, 1987, is transferred to the genus and redescribed. Confirming a hypothesis raised in the literature, Dysderina termitophila Bristowe, 1938, is transferred to Neoxyphinus and recognized as the senior synonym of the type species N. ogloblini Birabén, 1953. Two other species are transferred from Dysderina to Neoxyphinus: D. keyserlingi Simon, 1907, here recognized as the senior synonym of D. rugosa Bristowe, 1938, and D. furtiva Chickering, 1968, of which the male is described for the first time. In addition to the redescription of N. termitophilus, n. comb., N. hispidus, n. comb., N. xyphinoides (Chamberlin and Ivie, 1942), N. keyserlingi, n. comb., and N. furtivus, n. comb., five new species are described: N. petrogoblin Abrahim and Ott, from the Amazon basin in Brazil, Colombia, Ecuador, and Peru; N. gregoblin Abrahim and Santos, from Venezuela; N. axe Abrahim and Brescovit, from Bahia, Brazil; N. boibumba Abrahim and Rheims, from Pará, Brazil; and N. barreirosi Abrahim and Bonaldo, from Brazil, Colombia, Guyana, and Venezuela. With the exception of N. boibumba, known only from males, all new species are described from both sexes.

Download or read book The Brazilian Goblin Spiders of the New Genus Predatoroonops (Araneae, Oonopidae) written by and published by . This book was released on 2012 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The new endemic goblin spider genus Predatoroonops is erected for 17 new soft-bodied oonopid species from Brazil: Predatoroonops schwarzeneggeri, sp. nov., is the type species of the genus, P. poncho, sp. nov., P. billy, sp. nov., P. valverde, sp. nov., P. blain, sp. nov., P. maceliot, sp. nov., P. anna, sp. nov., P. rickhawkins, sp. nov., P. dutch, sp. nov., P. dillon, sp. nov., P. vallarta, sp. nov., P. phillips, sp. nov., P. yautja, sp. nov., P. peterharlli, sp. nov., P. mctiernani, sp. nov., P. chicano, sp. nov., and P. olddemon, sp. nov. Males of this new genus are easily diagnosed and separated from other Oonopinae genera by the extremely modified male chelicerae that frontally have median furrows and accentuated projections. The females can be recognized by the genitalia, which have a conspicuous posterior receptaculum, usually exposed between the epigastric folds. An auxiliary character for both sexes could be the presence of very long pairs of ventral spines with pronounced bases on the legs I and II tibiae and metatarsi. The genus is considered endemic and the species are recorded mainly from the Brazilian Atlantic Forest. An identification key is provided for all Predatoroonops species known to date.

Download or read book The Brazilian Goblin Spiders of the New Genus Guaraguaoonops (Araneae, Oonopidae) written by and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new endemic goblin spider genus Guaraguaoonops is erected to include two new soft-bodied oonopid species from Brazil: the type species, G. hemhem, distributed in the states of Maranhão, Piauí, and Ceará, and G. humbom, known only from Piauí. These spiders are unique among oonopids and easily diagnosed by the flattened carapace with a porrect clypeus, modified lateral setae on the carapace in both sexes, and male with a sinuous, flattened distal cheliceral projection and palp with ventral conical tegular projection. These species probably occupy a soil cryptic habit and are found in dry sand of "cerrado" areas in northeastern Brazil.

Download or read book An Update of the Goblin Spider Genus Birabenella Grismado, 2010 (Araneae, Oonopidae), with the Description of Three New Species written by Luis N. Piacentini and published by . This book was released on 2017 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: The taxonomy of the poorly known South American goblin spider genus Birabenella Grismado (Araneae: Oonopidae) is updated in light of recently collected material. Three new species are described: B. kamanchaca, from northern Chile, B. portai, from northwestern Argentina, and B. chincha, from southern Peru, where the genus is reported for the first time. The diagnosis of the genus is updated; the presence of the ventral digitiform projection on the male copulatory bulb in the three newly described species supports this character as a putative synapomorphy for the genus. Additionally, all species in this genus possess unipectinate tarsal claws. Preliminary observations indicate that there is some degree of variability in tarsal organ morphology.

This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new genus, Birabenella, is erected for three new soft-bodied oonopid species from Coquimbo Region, Chile (B. homonota, the type species, B. elqui, and B. pizarroi) and one from Catamarca Province, Argentina: B. argentina (Birabén, 1955), here transferred from Oonopinus Simon. The new genus is supported and diagnosed by the tarsal claws with one row of teeth, and by the stout and flattened setae on the dorsum of the abdomen. The thickened anterior wall of the posterior receptacle in female genitalia, and the ventral digitiform projection on the bulb of the male palp are also probable synapomorphies.
Book Synopsis The South American Goblin Spiders of the New Genera Pseudodysderina and Tinadysderina (Araneae, Oonopidae) by : Norman I. Platnick
Download or read book The South American Goblin Spiders of the New Genera Pseudodysderina and Tinadysderina (Araneae, Oonopidae) written by Norman I. Platnick and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new genus, Pseudodysderina, is established for a group of species that resemble those of Dysderina Simon in having grooves connecting both the anterior and posterior spiracles. These spiders have transverse ridges on the sternum but lack the sternal excavations that characterize Dysderina and are instead united by the highly modified mouthparts of males: the labium is greatly enlarged, with a dorsoventrally flat, posterior portion that extends far posterior of the anterolateral corners of the sternum, and the endites are each deeply excavated, medially around the sides of the labium and laterally around the base of the palpal trochanter. Dysderina desultrix (Keyserling), from Peru, is transferred to Pseudodysderina and chosen as the type species; its male is described for the first time. This species has been taken by canopy fogging and beating foliage as well as in leaf litter, and appears to be widespread in the Amazonian portions of Colombia, Ecuador, Peru, and Brazil. Seven more narrowly distributed new species are described from Peru (P. manu), Bolivia (P. yungas, P. beni), Ecuador (P. hermani), Colombia (P. suiza, P. dracula), and Brazil (P. utinga). The six new species assigned to the new genus Tinadysderina resemble those of Dysderina and Pseudodysderina, but have a much smaller, simpler, weakly sclerotized embolus; they are known only from the western slopes of the Andes in Ecuador (T. tinalandia, T. otonga) and Colombia (T. planada, T. gorgona, T. bremen, T. pereira).

This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goblin spider genus Dysderina Simon is relimited to include only those members of the Dysderina complex that have three pairs of deep, steeply sided excavations extending from the sides of the sternum toward the midline; two species groups are recognized. The principalis group contains those species whose members have strong, transverse ridges connecting the posterior edges of each pair of sternal excavations, including the type species, D. principalis (Keyserling) from Colombia (the female of which is described for the first time), plus seven new species from Colombia (D. sasaima, D. cunday, D. amaca) and Ecuador (D. sacha, D. erwini, D. baehrae, D. excavata). The tiputini group contains species whose members lack transverse sternal ridges, and includes five new species from Ecuador (D. tiputini), Colombia (D. ayo, D. matamata, D. craigi), and Brazilian Amazonia (D. urucu). A new genus, Tridysderina, is established for a group of species whose members have a flat, smooth sternum with one or two transverse ridges at the level of coxae II and III, but without a transverse ridge at the level of coxa IV; the genus includes six new species from Ecuador (T. yasuni, T. jatun, T. galeras, T. archidona, T. tena, T. bellavista).
