Download or read book On Puan, a New Genus of Goblin Spiders from Argentina (Araneae, Dysderoidea, Oonopidae) written by Matías Andrés Izquierdo and published by . This book was released on 2012 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new genus of Oonopidae, Puan, is described from Argentina. The genus exhibits several features also found in orsolobids, including a well-sclerotized sperm duct and an H-shaped eye pattern. Puan resembles the oonopid genus Unicorn Platnick and Brescovit but differs in male palpal morphology. In addition, males lack the clypeal horn characteristic of Unicorn. Two new species, P. chechehet and P. nair, are described from the southwestern mountains of Buenos Aires Province. Complex copulatory bulbs are the principal characteristic of these species and could be a synapomorphy for the genus.

Download or read book Behaviour and Ecology of Spiders written by Carmen Viera and published by Springer. This book was released on 2017-11-02 with total page 448 pages. Available in PDF, EPUB and Kindle. Book excerpt: Within the last few decades, arachnology in the Neotropical region has experienced a great development filling the knowledge gap in one of the most diverse regions of the world. Nevertheless, large geographical areas remain poorly sampled, especially within the Amazon, and new genera and species have been continuously discovered, even in urban areas. In congruence with the recent improvements in research, several aspects of the ecology, behaviour and natural history of spiders, such as interactions with other predators and parasitoids, social interactions, dispersal patterns, habitat requirements, mating behaviors, among others, are being carefully investigated. These recent contributions incorporate substantial information on the preexisting knowledge on these subjects every year. Our main objective with this book is to present a summary on these new researches and on the currently knowledge on the main subjects involved in the general theme, emphasizing the contribution of the rich fauna of the Neotropical region to the research of behaviour and ecology of the spiders.

Xestaspis reimoseri Fage is transferred to Hexapopha as the type species, its female is described for the first time, and three new species (H. hone, H. jimenez, and H. osa) are described. Dysderina caeca Birabén, from Argentina, is transferred to Coxapopha.
Book Synopsis The Neotropical Goblin Spiders of the New Genus Varioonops (Araneae, Oonopidae) by : Angelo Bolzern
Download or read book The Neotropical Goblin Spiders of the New Genus Varioonops (Araneae, Oonopidae) written by Angelo Bolzern and published by . This book was released on 2013 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new genus, Varioonops, is established for a group of species characterized by sexual dimorphism in abdomen morphology (with a dorsal scutum present in males but not females), male palps with a separate cymbium and bulb, and a patterned abdomen. The closest relatives of the new genus appear to be three similar, but as yet undescribed, Neotropical genera that share those characters, but the members of Varioonops are united by a putative synapomorphy that does not seem to occur in those undescribed groups: a granulated sternum. Attention is drawn to the cymbial cone, a structure (possibly a receptor) found near the tip of the cymbium in Varioonops, members of the Orchestininae, and at least some soft-bodied members of the Oonopinae. A total of 23 new species are described: V. cafista (the type species), V. velsala, V. montesta, V. spatharum, V. poas, V. varablanca, V. tortuguero, V. veragua, V. heredia, and V. girven from Costa Rica, V. ramila and V. sansidro from Costa Rica and Panama, V. funator and V. cerrado from Panama, V. edvardi and V. sinesama from Colombia, and V. yacambu, V. trujillo, V. pittieri, V. chordio, V. parlata, V. potaguo, and V. grancho from Venezuela.
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 43 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).
Book Synopsis The Goblin Spider Genus Costarina (Araneae, Oonopidae). by : Norman I. Platnick
Download or read book The Goblin Spider Genus Costarina (Araneae, Oonopidae). written by Norman I. Platnick and published by . This book was released on 2014 with total page 67 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Costarina faunas of Panama and Colombia are revised. Because Chickering described the sexes from his Panamanian collections separately, several of his names based only on females are placed as junior synonyms of names based only on males: C. humphreyi (Chickering) is newly synonymized with C. recondita (Chickering), as are C. belinda (Chickering) with C. intempina (Chickering), C. rigida (Chickering) with C. abdita (Chickering), C. silvatica (Chickering) with C. dura (Chickering), and C. improvisa (Chickering) with C. seclusa (Chickering). The Costa Rican species C. pittier Platnick and Berniker is newly recorded from Panama. Nine new species are described from Panama (C. sorkini, cerrocol, bocas, chiriqui, clara, fortuna, almirante, dybasi, and tskui), as are 11 from Colombia (C. sasaima, suiza, otun, choco, yotoco, saladito, antonio, anchicaya, gorgona, helechal, and taraira). Previous studies on more northern species are supplemented; newly available collections from Nicaragua reveal the presence there of two new species (C. kilambe and diablo), and locality records are provided for the Costa Rican members of the genus.

Book Synopsis The Goblin Spider Genus Pescennina (Araneae, Oonopidae) by : Norman I. Platnick
Download or read book The Goblin Spider Genus Pescennina (Araneae, Oonopidae) written by Norman I. Platnick and published by . This book was released on 2011 with total page 64 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goblin spider genus Pescennina Simon has been known only from females of its type species from Venezuela, whereas the more recently described genus Marsupopaea Cooke has been known only from males taken in Colombia. Discovery of the missing sexes, in both cases, indicates that these spiders belong to the Scaphiella complex; males have dorsal abdominal scuta that are absent in females. The presence, in the males of both type species, of a terminal, coiled embolus that can be held in an excavated "pouch" at the anterior edge of the sternum and is matched by coiled anterior ducts in the female genitalia, suggests that these taxa are congeneric. Marsupopaea is therefore newly synonymized with Pescennina, and its type species, M. sturmi Cooke, is placed as a junior synonym of P. cupida (Keyserling). Species of Pescennina occur widely in North, Central, and South America; many are apparently ant mimics, with color patterns (and sometimes a constricted abdomen) that enhance their antlike appearance. Although most of the species seem to be ground dwelling, with the extremely narrow geographic ranges typical of goblin spiders, at least four species inhabit the forest canopy, and at least one of those species is much more widespread. Males of the type species, P. epularis Simon, and females of P. cupida (Keyserling) are described for the first time; 16 new species are described: P. iviei, P. gertschi, P. sumidero, and P. ibarrai from Mexico; P. murphyorum from Nicaragua and Costa Rica; P. viquezi from Costa Rica; P. laselva from Costa Rica and Panama; P. fusca from Panama; P. arborea from Panama, Colombia, and Ecuador; P. magdalena and P. sasaima from Colombia; P. orellana from Ecuador; P. piura and P. loreto from Peru; P. grismadoi from Bolivia; and P. otti from southern Brazil.
Book Synopsis The Goblin Spider Genus Khamisia and Its Relatives (Araneae, Oonopidae) by : Norman I. Platnick
Download or read book The Goblin Spider Genus Khamisia and Its Relatives (Araneae, Oonopidae) written by Norman I. Platnick and published by . This book was released on 2015 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goblin spider genus Khamisia Saaristo and van Harten was based on a single female from Yemen characterized by large lateral extensions of the sternum that widely separate coxae II and III. Three new species, including the first known males of the genus, are described: K. hayer from the United Arab Emirates, K. atlit from Israel, and K. holmi from Kenya. All these species are united by having only two trichobothria on the palpal tibia; K. hayer has apparently been introduced into Cape Verde. Other specimens with a similarly modified sternum have been found in Africa, Madagascar, and the Virgin Islands, but differ in having the normal set of three trichobothria on the palpal tibia. The new genus Khamisina is established for three new species that also differ in having an abdominal color pattern, a punctate sternum, and uniquely shaped cheliceral setae: K. kivu from DR Congo, K. kilifi from Kenya, and K. ibadan from Nigeria. A second new genus, Khamiscar, is established for six new species from Madagascar in which the sternum is widened posteriorly and bears marginal radiating ridges, and the tarsal organs have only a single raised receptor: K. anta, K. maro, K. tola, K. kiri, K. baly, and K. ambi. A third new genus, Khamisoides, is established for three bizarre new species from the Virgin Islands (K. muchmorei from St. Croix; K. edwardsi and K. calabash from St. John) that differ in having only two eyes, fused posterior median spinnerets, and female genitalia with a pair of lateral receptacula and anteriorly directed apodemes.
Book Synopsis The Neotropical Goblin Spiders of the New Genus Reductoonops (Araneae, Oonopidae) by : Norman I. Platnick
Download or read book The Neotropical Goblin Spiders of the New Genus Reductoonops (Araneae, Oonopidae) written by Norman I. Platnick and published by . This book was released on 2014 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new genus, Reductoonops, is established for a group of New World soft-bodied oonopine spiders, found from Mexico south to Chile, characterized by reduced size, a flattened clypeus, loss of the posterior median spinnerets, and often by loss of the four posterior eyes. Members of this group resemble those of Stenoonops Simon but lack the clump of short setae found on the dorsal surface of the palpal tarsus of both sexes in that genus, and often have four pairs of deep channels at the sides of the sternum, the most anterior pair of which demarcate a short, trapezoidal, anterior portion of the sternum. A total of 34 new species are described from Mexico (chamela, armeria, niltepec, real, nubes, jabin), Costa Rica (monte, lucha), Costa Rica and Panama (naci), Panama (almirante, escopeta, bayano), Jamaica (ferry), Curaçao (hato), Martinique (diamant), Colombia (marta, sasaima, meta, leticia), Ecuador (tandapi, pichincha, tina, domingo, otonga, palenque, napo, jatun, hedlite, molleturo, celica, yasuni), the Galapagos Islands (pinta), Peru (carpish), and Chile (elqui).
