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.

Available in PDF, EPUB and Kindle. Book excerpt: A new genus of soft-bodied oonopids, Neotrops, is established for a large assemblage of goblin spiders found in all tropical and subtropical areas of the Neotropical region, from Panama to Uruguay and central Argentina. Members of Neotrops have spinose forelegs, and share a general palpal morphology with those of Heteroonops Dalmas, but have a prolateral conductor connected with an internal bulbal vesicle that presumably discharges its secretion through a prolateral slit. Females lack a posterior receptacle in the internal genitalia, having only a posterodorsal plate serving for muscle attachment. Here we treat all the species except those from Brazil, which will be addressed in a subsequent paper. Twenty-three new species are described: N. darwini (type species), N. lorenae, and N. sciosciae (from Argentina and Uruguay); N. yunga, N. piacentinii, N. poguazu, and N. lopardoae (from Argentina); N. rubioi, N. pombero, and N. avalosi (from Argentina and Paraguay); N. labarquei (from Uruguay), N. yabare, N. izquierdoi, and N. kopuchianae (from Bolivia); N. pithecia, N. silvae, and N. pakitza (from Peru); N. platnicki, and N. waorani (from Ecuador); N. santamarta and N. caparu (from Colombia); and N. maracay and N. amacuro (from Venezuela). Four additional species, previously placed in Oonops Templeton, are transferred here to Neotrops: O. nigromaculatus Mello-Leitão, from Argentina and Uruguay; O. tucumanus Simon, from Argentina; O. donaldi Chickering, from Panama; and O. trapellus Chickering, from Trinidad and Venezuela. The females of the three latter species are here described for the first time. Most of the species are known from the leaf litter or the foliage of tropical and subtropical forests, but also from grasslands in the southern parts of their distributional range, where they appear as the dominant soft-bodied oonopids. The relationships of this new taxon are briefly discussed, and intrageneric groupings are also proposed.

Available in PDF, EPUB and Kindle. Book excerpt: The South Asian goblin spider genus Aprusia Simon (Araneae: Oonopidae) consists of five species and is found in southwestern India and Sri Lanka. Although the type species A. strenuous Simon is known only from two juvenile syntypes, new topotypical material from Sri Lanka allowed a redefinition of the genus and species. Ischnothyreus vestigator Simon, also from Sri Lanka, is transferred to Aprusia based on recently collected topotypical specimens. The female is described for the first time. Three new species are described: A. veddah Grismado and Deeleman, A. kataragama Grismado and Deeleman (both from Sri Lanka), and A. kerala Grismado and Deeleman (from southwestern India). The genus is recognized by the relatively small to medium-sized dorsal scutum on the abdomen of both sexes, the strong macrosetae on the forelegs and by the conformation of the male palp, with the cymbium and bulb fused and a tiny, slightly sclerotized embolus.

Available in PDF, EPUB and Kindle. Book excerpt: A new genus of soft-bodied oonopids, Gradunguloonops, is established for a group of goblin spiders found in the Amazonian rainforests of northern South America. Members of this genus differ from other oonopids in that the proclaw of tarsi I and II is notably larger than the corresponding retroclaw, a putative synapomorphy of the group. Gradunguloonopscomprises twelve species, all new and described in this contribution: G. mutum (type species) from Brazil and Peru, G. bonaldoi, G. amazonicus, G. urucu, G. pacanari, G. juruti from Brazil, G. erwini from Peru, G. orellana and G. nadineae from Ecuador, G. benavidesae and G. florezi from Colombia, and G. raptor from Venezuela. Two preliminary intrageneric groups are proposed on the basis of their female genital morphology: the bonaldoi group, to which are assigned the species with the anterior section comprising only a single anterior sclerite, and the mutum group, with a more complex, tripartite anterior section.

This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Three new genera of soft-bodied, oonopine goblin spiders are established. Two specific names (Oonops tolucanus Gertsch and Davis, Oonops chickeringi Brignoli) are transferred to the new genus Toloonops, characterized by retaining a separate palpal bulb and cymbium, having the cymbial cone near the cymbial margin, and having posteriorly directed projections on the male endites that originate far from the anterior endite margins; five new species are described: T. chiapa, T. jacala, T. veracruz, T. belmo, and T. verapaz. Six similar new species, united by having a stepped male endite profile and a subapical sclerite on the anterior genitalic process of females, are assigned to the new genus Guatemoonops: G. purulha, G. rhino, G. jaba, G. chilasco, G. augustin, and G. zacapa. Oonops mckenziei Gertsch is transferred to the new genus Emboonops, characterized by having a fused palpal bulb and cymbium, a hypertrophied embolus, and often a V-shaped female anterior genitalic process; nine new species are described: E. tuxtlas, E. tamaz, E. catrin, E. nejapa, E. calco, E. palenque, E. bonampak, E. arriaga, and E. hermosa.

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 0 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.

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).

This book was released on 2013 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new genus, Prodysderina, is established for a group of Neotropical oonopids belonging to the Dysderina complex and characterized by having a laterally incised, tuberculate, but unridged sternum, a groove connecting the posterior (but not the anterior) spiracles, and a male embolus with an elongated distal prong and a reduced proximal prong. Dysderina armata Simon is transferred to Prodysderina and selected as the type species; eight new species are described from Venezuela (P. megarmata, P. rollardae, P. janetae) and Colombia (P. piedecuesta, P. rasgon, P. santander, P. filandia, P. otun). The genus Aschnaoonops contains species that resemble those of Prodysderina but have a twisted (and usually basally widened) embolus in males, and a reduced genital atrium in females. That genus occurs in the Andes from Peru north to Colombia, east across northern South America, and north into the West Indies. Dysderina similis (Keyserling) and D. propinqua (Keyserling) from Colombia, and D. simla Chickering from Trinidad, are transferred to Aschnaoonops, and females of the two Keyserling species are described for the first time. One new species, A. silvae, has been taken by canopy fogging and appears to be widespread in the Amazonian portions of Peru, Ecuador, and Colombia. A total of 36 other new, ground-dwelling, microdistributed species are described: A. yasuni, A. tiputini, A. cosanga, A. ramirezi, A. jatun, and A. marshalli from Ecuador, A. leticia, A. orito, A. pira, A. paez, A. huila, A. meta, A. alban, A. chingaza, A. pamplona, A. pedro, and A. marta from Colombia, A. chorro, A. indio, A. tachira, A. tariba, A. teleferico, A. jaji, A. merida, A. aquada, A. masneri, A. trujillo, A. cristalina, A. bocono, A. simoni, and A. margaretae from Venezuela, A. malkini, A. caninde, and A. belem from Brazil, A. villalba from Puerto Rico, and A. gorda from the Virgin Islands. Another new genus, Bidysderina, is established for a group of species resembling those above in sternal structure but having differently constructed male palps; five new species (B. perdido, B. bifida, B. niarchos, B. wagra, B. cayambe) are described from Napo province, Ecuador.
