The effectiveness and efficiency of two microcomputer parsimony programs (Felsenstein s PHYLIP and Swofford s PAUP), and a prototype version of a third (SHEN, to be incorporated in Farris HENNIG-86), are evaluated with reference to 35 data sets, including those previously used by Luckow and Pimentel (1985) to benchmark mainframe programs. Both PHYLIP and PAUP can be used effectively; with careful selection of options, their accuracy can equal or surpass that of older mainframe programs. PHYLIP is relatively inefficient (in use of computer time); its usefulness is also limited by the inability of its heuristic algorithms to detect multiple equally parsimonious solutions in a single run. PHYLIP s exact algorithm (branch-and-bound) and PAUP s heuristic and exact algorithms do not share the latter drawback but require users to spend unreasonable amounts of time coping with redundant output. The remarkable effectiveness of these programs offers hope that (particularly with the advent of multitasking microcomputers) exact and cost-effective solutions will be obtainable in many, if not all, cladistic analyses. 24 pp., 14 tabs, gr. 8.…

The previously monotypic subfamily Physogleninae Petrunkevitch is redefined to include Physoglenes Simon - containing P. vivesi Simon and three new species from Chile - and three new genera: Meringa, containing nine new species from New Zealand; Tupua, containing four new species from Tasmania; and Paratupua, containing one new species from Victoria. The physoglenine genera are united by unique modifications of the male pedicel and anterior abdominal region. The new subfamily Pahorinae is established for five new genera from New Zealand: Pahora (containing nine new species), Pahoroides (containing two new species), Wairua (containing two new species), Nomaua [containing five new species and N. crinifrons (Urquhart), transferred from the linyphiid genus Bolyphantes], and Runga (containing five new species). The pahorine genera are united by a carapace-abdomen stridulatory system, secretory pores on the male pars cephalica, and a deeply excavated paracymbial area on the male palp. Three other genera seem closely related to physoglenines and pahorines: Mangua, new genus, containing 13 new species and M. forsteri (Brignoli), transferred from Linyphia, all from New Zealand; Chileotaxus, new genus, containing one new species from Chile; and the Neotropical genus Synotaxus Simon. These spiders have been widely separated in some past classifications; Physoglenes has been variously considered a leptonetid, pholcid, theridiid, or araneoid incertae sedis, whereas the other previously described taxa have generally been considered theridiids or linyphiids. All 12 genera are united by the presence of a small, basally situated and dorsally excavated paracymbium, a longitudinal incision of the retrolateral cymbial margin, thickened (and sometimes spiniform) dorsal macrosetae on the male palpal femur, patella, and/or tibia, and greatly elongated, spineless legs, with the first pair much the longest and all femora basally thickened. The known web forms are diverse, including an irregular sheet (Mangua and at least some physoglenines), an inverted bowl (pahorines), and a latticelike structure (Synotaxus). The absence of a comb on tarsi IV and widened aggregate spigots on the posterior lateral spinnerets, and the presence ofa basal paracymbium, indicate that these genera do not belong to the Theridiidae, and the male palpi lack the distinct embolic division including a radix typical of the Linyphiidae. The oldest family-group name available for the assemblage is Synotaxidae, based on Synotaxeae Simon. Synotaxidae is hypothesized to be the sister group of Nesticidae plus Theridiidae. Wunderlich s synonymy of the families Hadrotarsidae and Theridiidae appears to be justified by paracymbial morphology; two possibly monophyletic groups can be recognized among the genera that are currently considered valid members of those families. The genera Anatea Berland, Audifia Keyserling, Dipoena Thorell, Dipoenata Wunderlich, Euryopis Menge, Gmogola Keyserling, Guaraniella Baert, Hadrotarsus Thorell, Lasaeola Simon, and Yoroa Baert are apparently united by a suite of characters (a dorsoventrally flattened female palpal claw, shortened chelicerae with elongated fangs, specialized ventral setae on tarsus I, a series of parallel ridges on the medial surface of the anterior lateral spinnerets, and four rather than two spermathecae) and may all be specialized predators of ants; the earliest available name for the assemblage is Hadrotarsinae Thorell. At least the genera Anelosimus Simon, Chrosiothes Simon, Chrysso O. P.-Cambridge, Coleosoma O. P.-Cambridge, Helvibis Keyserling, Nesticodes Archer, Rugathodes Archer, Spintharus Hentz, Tekellina Levi, Theridula Emerton, Thwaitesia O. P.-Cambridge, and Thymoites Keyserling are apparently united by a distinctive paracymbial hood. The name Spintharinae Simon is available for this assemblage; if Spintharinae is monophyletic, the genera Achaearanea Strand and Anelosimus, as currently construed, may be polyphyletic assemblag.…

The Australasian ground spiders belonging to the family Prodidomidae are monographed; although only ten species were previously known from the region, the fauna is extraordinarily diverse, encompassing at least seven genera and 138 species. Two generic names are newly synonymized: Hyltonia Birab?n with Prodidomus Hentz, and Honunius Simon with Molycria Simon. The type species of the family, Prodidomus rufus Hentz, although originally described from Alabama, is apparently synanthropic and hence widespread; Prodidomus gulosus (Simon) from New Caledonia, Prodidomus imaidzumii Kishida from Japan, and Hyltonia scottae Birab?n from Argentina are newly synonymized with P. rufus, and the species is newly recorded from Chile and St. Helena. Seven new species of Prodidomus are described from Western Australia, the Northern Territory, and Queensland. The females of Molycria mammosa (O. P.-Cambridge) and Molycria quadricauda (Simon) are described for the first time, and 34 new species of Molycria are described. The new genus Wydundra is described for 40 new Australian species, and Molycria voc Deeleman-Reinhold, from Malaysia and the Moluccas, is transferred to Wydundra. Molycria splendida Simon is transferred to the new genus Wesmaldra, its male is described for the first time, and 13 new species of Wesmaldra are described from Western Australia and the Northern Territory. Molycria flavipes Simon is transferred to the new genus Nomindra, its male is newly described, Molycria alboplagiata Simon is newly synonymized with that name, and 15 new species of Nomindra are described. The male of Cryptoerithus occultus Rainbow is described for the first time, and 18 new species are assigned to Cryptoerithus. Adult males and females of Myandra cambridgei Simon are described for the first time, as are two new species of Myandra. New York. 287 pp., 658 figs, 47 maps, br. gr.8.…

The monogeneric tribe Orsolobini Cooke is removed from the Dysderidae, elevated to familial status, and redefined to include those dysderoids with a raised tarsal organ. As relimited, the family contains 170 species from Australia, Tasmania, New Zealand, the Auckland and Campbell islands, Chile, Argentina, and the Falkland Islands. Six genera are transferred from the Oonopidae to the Orsolobidae: Tasmanoonops Hickman, Cornifalx Hickman, Ascuta Forster, Duripelta Forster, Pounamuella (nomen novum for Pounamua Forster, preoccupied), and Subantarctia Forster. Eighteen new genera are described: Falklandia (type species Orsolobus rumbolli Schiapelli and Gerschman from the Falkland Islands), Mallecolobus (type species M. malacus, new species, from Chile; also including three other new species from Chile), Chileolobus (type species C. eden, new species, from Chile), Osornolobus (type species O. canan, new species, from Chile; also including 16 new species from Chile), Hickmanolobus (type species Oonopinus mollipes Hickman from Tasmania, transferred from the Oonopidae), Australobus (type species A. torbay, new species, from Western Australia), Waipoua (type species W. toronui, new species, from New Zealand; also including Pounamua totara Forster from New Zealand, P. gressitti Forster from Campbell Island, and five other new species from New Zealand), Wiltonia (type species W. graminicola, new species, from New Zealand; also including eight other new species from New Zealand), Tautukua (type species T. isolata, new species, from New Zealand), Bealeyia (type species B. unicolor, new species, from New Zealand), Dugdalea (type species D. oculata, new species, from New Zealand), Anopsolobus (type species A. subterraneus, new species, from New Zealand), Turretia (type species T. dugdalei, new species, from New Zealand), Orongia (type species O. medialis, new species, from New Zealand; also including two other new species from New Zealand), Paralobus (type species Ascuta salmoni Forster from New Zealand), Tangata (type species T. nigra, new species, from New Zealand; also including Ascuta stewartensis Forster, A. rakiura Forster, A. orepukiensis Forster, A. alpina Forster, A. plena Forster, and 11 other new species from New Zealand), Maoriata (type species Ascuta magna Forster from New Zealand; also including two new species from New Zealand), and Waiporia (type species W. wiltoni, new species, from New Zealand; also including Ascuta extensa Forster, A. modica Forster, A. algida Forster, A. mensa Forster, Pounamua hornabrooki Forster, and six other new species from New Zealand). Sixty-two other new species are described in previously established genera: seven Orsolobus from Chile and Argentina, 25 Tasmanoonops from Australia and Tasmania, and 10 Ascuta, 13 Duripelta, 3 Pounamuella, and 4 Subantarctia from New Zealand. Ascuta pallida Forster is transferred to Duripelta. The females of Tangata rakiura (Forster), T. plena (Forster), Waiporia modica (Forster), and Pounamuella ramsayi (Forster) and the male of P. australis (Forster) are described for the first time. The characters of the four dysderoid families are reviewed. 230 pp., 889 figs, br. gr. 8. …
