Item A new genus of pholcid spiders (Araneae, Pholcidae) endemic to western Cuba, with a case of female genitalic dimorphism. American Museum novitates ; no. 3329(New York, NY : American Museum of Natural History, 2001) Huber, Bernhard A.; Pérez González, Abel.Four species of Ciboneya Pérez, n. gen. are described from western Cuba: C. nuriae, n. sp. from La Habana and Pinar del Rio provinces, C. odilere, n. sp., C. parva, n. sp., and C. antraia, n. sp. from Pinar del Rio Province. The species share apophyses on the male cheliceral fangs, corresponding pockets or modified areas on the female epigynum, and several details of the male pedipalps. Vertical hairs on the tibiae and metatarsi of the male legs and a retrolateral coxa apophysis on the male palp place the genus closer to other Central or South American genera of the New World clade of pholcids, but the exact sister group is obscure. The spiders live in the leaf litter and under rocks in humid forests, or near the floor in caves. The females of C. antraia show a remarkable dimorphism in their genitalia, with rare intermediate forms. The possibly more frequent occurrence of such a dimorphism and the probable bias toward reporting it as two different species are discussed.Item New World pholcid spiders (Araneae, Pholcidae) : a revision at generic level. Bulletin of the AMNH ; no. 254([New York] : American Museum of Natural History, 2000) Huber, Bernhard A.New World pholcids are revised at the generic level, with an emphasis on South America. A total of 47 extant genera occur in the New World, 22 of which are newly described. A preliminary key to the genera of the New World is presented. Redescriptions are given for 11 genera and for 59 species, and 106 species are newly described. Three generic names and 14 specific names are newly synonymized ... A numerical cladistic analysis is performed using a matrix of 61 taxa (48 of them New World pholcids) and 61 morphological characters. The main results of the analysis are as follows: (1) Pholcids are strongly supported as a monophyletic group. (2) Phoicids are separated into the following clades, which are tentatively named to emphasize their character as a working hypothesis: "ninetines," "pholcines" (Metagonia Simon and the Pholcus group sensu Huber), "holocnemines" (Holocnemus group sensu Timm, Artema Walckenaer, Physocyclus Simon, and Priscula Simon), and the "New World clade." Their interrelationships are not definitively resolved. (3) New World pholcids are an assemblage of representatives of all major clades within the family, but most genera are part of the New World clade, which is the only clade restricted to the New World. (4) A hypothesis concerning the evolutionary transformation of characters is given for 41 of the 54 traits scored that vary among pholcids. The following names are newly synonymized: Anomalaia González-Sponga, 1998, with Metagonia Simon, 1893; Blechroscelis Simon, 1893, with Priscula Simon, 1893; Myrmidonella Berland, 1919, with Ninetis Simon, 1890; Blechroscelis coeruleus (Keyserling, 1891), with Coryssocnemis (now Mesabolivar) togatus (Keyserling, 1891); Blechroscelis irroratus Mello-Leitão, 1947, Psilochorus browningi Roewer, 1951, and Blechroscelis virescens Mello-Leitão, 1947, with Blechroscelis (now Mesabolivar) aurantiacus (Mello-Leitão, 1930); Blechroscelis viridis Mello-Leitão, 1918, with Litoporus (now Mesabolivar) brasiliensis (Moenkhaus, 1898); Hypsorinus conwayi Mello-Leitão, 1947, with Priscula binghamae (Chamberlin, 1916); Priscula ranchograndensis González-Sponga, 1996, with Priscula venezuelana Simon, 1893; Litoporus abrahami Mello-Leitão, 1947, with Coryssocnemis (now Litoporus) uncatus (Simon, 1893); Litoporus coccineus Simon, 1893, Litoporus imbecillus (Keyserling, 1891), and Litoporus fulvus Moenkhaus, 1898, with Litoporus (now Mesabolivar) luteus (Keyserling, 1891); Micromerys occidentalis (Mello-Leitão, 1929), with Micropholcus fauroti (Simon, 1887); Pholcus dubiomaculatus Mello-Leitão, 1918, with Pholcus phalangioides (Fuesslin, 1775); Physocyclus dubius Mello-Leitão, 1922, with Physocyclus globosus (Taczanowski, 1874).Item Ninetis subtilissima Simon, 1890 (Araneae, Pholcidae) : redescription and SEM ultrastructure. American Museum novitates ; no. 3336(New York, NY : American Museum of Natural History, 2001) Huber, Bernhard A.; Harten, Antonius van.;Ninetis subtilissima Simon, 1890 is redescribed and some data on SEM microstructure are presented based on specimens collected near the type locality in Yemen.Item The pholcids of Australia (Araneae, Pholcidae) : taxonomy, biogeography, and relationships. Bulletin of the AMNH ; no. 260([New York] : American Museum of Natural History, 2001) Huber, Bernhard A.The pholcid spiders of Australia are revised. Only seven autochthonous genera are recognized: (1) Wugigarra, new genus, includes the Australian species previously assigned to Psilochorus Simon. This genus is largely restricted to eastern Australia. With 22 described species (20 of them new) and about 40 undescribed species in Australian collections, it is probably the most diverse genus on the continent. (2) Trichocyclus Simon is the dominant or only pholcid genus in most areas of Western and South Australia and the Northern Territory; 23 species are described, 20 of them new. (3) Micromerys Bradley is restricted to the tropical and subtropical areas of Queensland and Northern Territory; 7 species are described, 5 of them new. (4) Pholcus Walckenaer has within Australia the same distribution as does Micromerys; 4 autochthonous species are described, all new. Pholcus litoralis Koch is newly synonymized with P. phalangioides (Fuesslin). (5) Panjange Deeleman-Reinhold and Deeleman is represented by a single, previously described species in northern Queensland. (6) Spermophora is restricted to northeastern Queensland; 2 species are described, both new. (7) Belisana Thorell with a single new species in the tropical north of Queensland and Northern Territory. Nine pholcid species are introduced, some of them occurring throughout the continent. They are included in a key. A numerical cladistic analysis is performed using a matrix of 71 taxa (10 of them Australian) and 65 characters. This analysis suggests that the two highly diverse genera (Wugigarra, Trichocyclus) are most closely related to New World, African, and Middle Eastern genera. All other genera are included in the Pholcus group sensu Huber. It is argued that these are probably new tropical elements, having entered Australia from the north probably not earlier than the Pleistocene, while Wugigarra and Trichocyclus are relicts of Gondwanaland, with their presence in Australia dating back to the Mesozoic.Item The spider genus Crossopriza (Araneae, Pholcidae) in the New World. American Museum novitates ; no. 3262(New York, NY : American Museum of Natural History, 1999) Huber, Bernhard A.; Deeleman-Reinhold, Christa L.; Pérez González, Abel."Crossopriza Simon, 1893 (Pholcidae) is a predominantly Old World spider genus with only a few records from the New World. The present paper reevaluates the New World records, and shows that C. lyoni (Blackwall, 1867), a synanthropic spider, has been recorded under several different names in various parts of the world and is the only unequivocal species in the New World. New junior synonyms of C. lyoni are C. brasiliensis Mello-Leitão, 1935, from Brazil; C. mucronata Mello-Leitão, 1942, from Argentina; and C. francoisi Millot, 1946, and C. stridulans Millot, 1946, from Madagascar. We present a detailed redescription and several new records for C. lyoni. The Argentine C. saltensis Mello-Leitão, 1941, is newly synonymized with Priscula binghamae (Chamberlin, 1916)"--P. [1].
