Item Australian goblin spiders of the genus Ischnothyreus (Araneae, Oonopidae). (Bulletin of the American Museum of Natural History, no. 389)(American Museum of Natural History., 2014-06-06) Edward, Karen L.; Harvey, Mark S.; Goblin Spider Planetary Biodiversity Inventory.Goblin spiders of the genus Ischnothyreus are characterized by small, heavily sclerotized male pedipalps, reduced dorsal and ventral scutes, and heavy spination of the first and second legs. Species of this genus may be distinguished from each other by the variation in the embolic region of the male palp, female genitalia, color, degree and shape of dorsal and ventral sclerotization, and specializations of the chelicerae and endites in the male. A total of 34 Australian species of Ischnothyreus Simon are recognized, all of which are endemic and found throughout the tropical, monsoonal, and subtropical regions of the country. Ischnothyreus darwini Edward and Harvey is the only previously described species, and 33 are newly described: I. arcus, I. barratus, I. bifidus, I. binorbis, I. boonjee, I. bualveus, I. bupariorbis, I. collingwoodi, I. comicus, I. corniculatum, I. cornuatus, I. crenulatus, I. culleni, I. digitus, I. eacham, I. eungella, I. florence, I. hamatus, I. hoplophorus, I. julianneae, I. ker, I. meidamon, I. monteithi, I. nourlangie, I. ovinus, I. piricius, I. pterodactyl, I. puruntatamerii, I. raveni, I. rixi, I. stauntoni, I. tragicus, and I. tumidus. Many of the described species have extremely small geographic ranges, and the genus shows high diversity over relatively small areas. A key, detailed illustrations, and digital images are provided for all Australian species of Ischnothyreus.Item The goblin spiders of the new endemic Australian genus Cavisternum (Araneae, Oonopidae). (American Museum novitates, no. 3684)(New York, NY : American Museum of Natural History., 2010) Baehr, Barbara, 1953-; Harvey, Mark S.; Smith, Helen M. (Helen Motum)The new endemic Australian goblin spider genus Cavisternum, gen. nov., is described with 19 new species: C. bagleyae, C. barthorum, C. bertmaini, C. carae, the type species C. clavatum, C. digweedi, C. ewani, C. foxae, C. gatangel, C. heywoodi, C. hughesi, C. ledereri, C. maxmoormanni, C. mayorum, C. michaelbellomoi, C. noelashepherdae, C. rochesterae, C. toadshow, and C. waldockae. A key is provided for all Cavisternum species known to date. Males of the genus Cavisternum possess a highly modified sternum, which is strongly concave and covered with clavate setae, and the cheliceral fangs are elongate with broad tips. The genus is found in tropical northern Australia and shows high endemicity, with most species recorded from a single location.Item High resolution images for Australian goblin spiders of the genus Ischnothyreus (Araneae, Oonopidae). (Bulletin of the American Museum of Natural History, no. 389)(2014-06-10) Edward, Karen L.; Harvey, Mark S.; Goblin Spider Planetary Biodiversity Inventory.High resolution images for Australian goblin spiders of the genus Ischnothyreus (Araneae, Oonopidae). (Bulletin of the American Museum of Natural History, no. 389) - http://hdl.handle.net/2246/6532Item The new Australasian goblin spider genus Prethopalpus (Araneae, Oonopidae). (Bulletin of the American Museum of Natural History, no. 369)(American Museum of Natural History., 2012-06-21) Baehr, Barbara, 1953-; Harvey, Mark S.; Burger, Matthias, 1976-; Thoma, Marco.The new goblin spider genus Prethopalpus is restricted to the Australasian tropics, from the lower Himalayan Mountains in Nepal and India to the Malaysian Peninsula, Indonesia, Papua New Guinea, and Australia. Prethopalpus contains those species with a swollen palpal patella, which is one to two times the size of the femur, together with a cymbium and bulb that is usually separated, although it is largely fused in four species. The type species Opopaea fosuma Burger et al. from Sumatra, and Camptoscaphiella infernalis Harvey and Edward from Western Australia are newly transferred to Prethopalpus. The genus consists of 41 species of which 39 are newly described: P. ilam Baehr ([male, female]) from Nepal; P. khasi Baehr ([male]), P. madurai Baehr ([male]), P. mahanadi Baehr ([male, female]), and P. meghalaya Baehr ([male, female]) from India; P. bali Baehr ([male]), P. bellicosus Baehr and Thoma ([male, female]), P. brunei Baehr ([male, female]), P. deelemanae Baehr and Thoma ([male]), P. java Baehr ([male, female]), P. kranzae Baehr ([male]), P. kropfi Baehr ([male, female]), P. leuser Baehr ([male, female]), P. magnocularis Baehr and Thoma ([male]), P. pahang Baehr ([male]), P. perak Baehr ([male, female]), P. sabah Baehr ([male, female]), P. sarawak Baehr ([male]), P. schwendingeri Baehr ([male, female]), and P. utara Baehr ([male, female]) from Indonesia and Malaysia; and P. alexanderi Baehr and Harvey ([male]), P. attenboroughi Baehr and Harvey ([male]), P. blosfeldsorum Baehr and Harvey ([male]), P. boltoni Baehr and Harvey ([male, female]), P. callani Baehr and Harvey ([male, female]), P. cooperi Baehr and Harvey ([male]), P. eberhardi Baehr and Harvey ([male, female]), P. framenaui Baehr and Harvey ([male, female]), P. humphreysi Baehr and Harvey ([male, female]), P. kintyre Baehr and Harvey ([male]), P. scanloni Baehr and Harvey ([male]), P. pearsoni Baehr and Harvey ([male]), P. julianneae Baehr and Harvey ([male]), P. maini Baehr and Harvey ([male, female]), P. marionae Baehr and Harvey ([male, female]), P. platnicki Baehr and Harvey ([male, female]), P. oneillae Baehr and Harvey ([male]), P. rawlinsoni Baehr and Harvey ([male]), and P. tropicus Baehr and Harvey ([male, female]) from Australia and Papua New Guinea. Three separate keys to species from different geographical regions are provided. Most species are recorded from single locations and only three species are more widely distributed. A significant radiation of blind troglobites comprising 14 species living in subterranean ecosystems in Western Australia is discussed. These include several species that lack abdominal scuta, a feature previously used to define subfamilies of Oonopidae.Item A new species of Urodacus (Scorpiones, Urodacidae) from Western Australia. (American Museum novitates, no. 3748)(American Museum of Natural History., 2012-06-25) Volschenk, Erich S.; Harvey, Mark S.; Prendini, Lorenzo.A new urodacid scorpion, Urodacus butleri, n. sp., is described from Barrow Island and the Pilbara bioregion of Western Australia. This species is unusually dark in color; it is compared and contrasted with three morphologically similar species, Urodacus manicatus (Thorell, 1876), Urodacus novaehollandiae Peters, 1861, and Urodacus planimanus Pocock, 1893.Item Sicariomorpha, a new myrmecophilous goblin spider genus (Araneae, Oonopidae) associated with Asian army ants. (American Museum novitates, no. 3843)(American Museum of Natural History., 2015-11-23) Ott, Ricardo.; Von Beeren, Christoph.; Hashim, Rosli.; Witte, Volker (Biologist); Harvey, Mark S.A new genus of oonopid spider, Sicariomorpha Ott and Harvey, is named for the type and only known species, Gamasomorpha maschwitzi Wunderlich from Malaysia. The most striking feature of the spider is the eyes, which are arranged in two widely separated triads. Besides taxonomic description, we summarize the biology of Sicarimorpha maschwitzi, which is a kleptoparasite of the Southeast Asian army ant Leptogenys distinguenda (Emery) and one among only few well-studied myrmecophilous spiders. Its morphology, behavior and life history seem to be well adapted for the life with its predatory army ant host.Item Tarsal organ morphology and the phylogeny of goblin spiders (Araneae, Oonopidae), with notes on basal genera. (American Museum novitates, no. 3736)(American Museum of Natural History., 2012-02-29) Platnick, Norman I.; Abrahim, Naiara.; Alvarez-Padilla, Fernando.; Andriamalala, Daniela.; Baehr, Barbara, 1953-; Baert, L.; Bonaldo, Alexandre B.; Brescovit, Antonio D.; Chousou-Polydouri, Natalia.; Dupérré, N. (Nadine); Eichenberger, Beata.; Fannes, Wouter.; Gaublomme, Eva.; Gillespie, Rosemary G., 1957-; Grismado, Cristian J.; Griswold, Charles E.; Harvey, Mark S.; Henrard, Arnaud.; Hormiga, Gustavo.; Izquierdo, Matías A.; Jocqué, R.; Kranz-Baltensperger, Yvonne.; Kropf, Christian.; Ott, Ricardo.; Ramírez, Martín J.; Raven, Robert J.; Rheims, Cristina A.; Ruiz, Gustavo R. S.; Santos, Adalberto J.; Saucedo, Alma D.; Sierwald, Petra.; Szűts, Tamás.; Ubick, Darrell.; Wang, Xin-Ping.Based on a survey of a wide variety of oonopid genera and outgroups, we hypothesize new synapomorphies uniting the Oonopidae (minus the South African genus Calculus Purcell, which is transferred to the Orsolobidae). The groundplan of the tarsal organ in Oonopidae is hypothesized to be an exposed organ with a distinctive, longitudinal ridge originating from the proximal end of the organ, and a serially dimorphic pattern of 4-4-3-3 raised receptors on legs I-IV, respectively. Such organs typify the diverse, basal, and ancient genus Orchestina Simon. Several other genera whose members resemble Orchestina in retaining two plesiomorphic features (an H-shaped, transverse eye arrangement and a heavily sclerotized, thick-walled sperm duct within the male palp) are united by having tarsal organs that are partly (in the case of Cortestina Knoflach) or fully capsulate (in the case of Sulsula Simon, Xiombarg Brignoli, and Unicorn Platnick and Brescovit). The remaining oonopids are united by the loss of the heavily sclerotized palpal sperm duct, presumably reflecting a significant transformation in palpal mechanics. Within that large assemblage, a 4-4-3-3 tarsal organ receptor pattern and an H-shaped eye arrangement seem to be retained only in the New Zealand genus Kapitia Forster; the remaining genera are apparently united by a reduction in the tarsal organ pattern to 3-3-2-2 raised receptors on legs I-IV and by the acquisition of a clumped eye arrangement. Three subfamilies of oonopids are recognized: Orchestininae Chamberlin and Ivie (containing only Orchestina; Ferchestina Saaristo and Marusik is placed as a junior synonym of Orchestina), Sulsulinae, new subfamily (containing Sulsula, Xiombarg, Unicorn, and Cortestina), and Oonopinae Simon (containing all the remaining genera, including those previously placed in the Gamasomorphinae). The type species of Sulsula and Kapitia, S. pauper (O. P.-Cambridge) and K. obscura Forster, are redescribed, and the female of S. pauper is described for the first time. A new sulsuline genus, Dalmasula, is established for Sulsula parvimana Simon and four new species from Namibia and South Africa.
