Book Description
An overview on the systematics of the stone huntsman spider genus Eusparassus Simon, 1903 and an identification key to the known species are presented. Six species-groups are proposed: the walckenaeri group (3 species, Eastern Mediterranean to Arabia and parts of North-Eastern Africa), dufouri group (8 species, Iberian Peninsula to parts of North-western Africa), vestigator group (3 species, Central to Eastern Africa and an isolated area in India), jaegeri group (4 species, Southern and South-Eastern Africa), tuckeri group (2 species, South-Western Africa) and doriae group (7 species, Middle East to Central and South Asia). Two species, E. pontii Caporiacco, 1935 and E. xerxes (Pocock, 1901) could not be placed in any of the above groups. The species from Africa and Arabia are revised. The following ten species are re-described: Eusparassus barbarus (Lucas, 1846), E. atlanticus Simon, 1909 stat. nov., E. syrticus Simon, 1909, E. oraniensis (Lucas, 1846), E. letourneuxi (Simon, 1874), E. fritschi (Koch, 1873) stat. rev., E. walckenaeri (Audouin, 1826), E. vestigator (Simon, 1897) comb. nov., E. laevatus (Simon, 1897) comb. nov. and E. tuckeri (Lawrence, 1927) comb. nov. The latter three species are transferred from Olios Walckenaer, 1837. Seven new species are described: Eusparassus arabicus spec. nov. (male, female) from Arabian Peninsula, E. educatus spec. nov. (male, female) from Namibia, E. reverentia spec. nov. (male, female) from Burkina Faso and Nigeria, E. jaegeri spec. nov. (male, female) from South Africa and Botswana, E. jocquei spec. nov. (male, female) from Zimbabwe, E. borakalalo spec. nov. (female) from South Africa and E. schoemanae spec. nov. (male, female) from South Africa and Namibia. Three taxa, E. dufouri maximus Strand, 1906 syn. nov., E. rufobrunneus Caporiacco, 1941 syn. nov. and Olios furcatus Lawrence, 1927 syn. nov. are proposed as junior synonyms of E. oraniensis, E. vestigator comb. nov. and E. tuckeri comb. nov. respectively. Males of E. atlanticus stat. nov. and E. fritschi stat. rev. are described for the first time as in the female of E. vestigator comb. nov. Neotypes are designated for E. barbarus, E. oraniensis and E. letourneuxi (all from Algeria). The male and female of Cercetius perezi Simon, 1902, which was known only from the immature holotype, are described here for the first time. This resulted in recognizing the monotypic and little used generic name Cercetius Simon, 1902 as a synonym of the widely used name Eusparassus. Nearly all the species are illustrated for the first time. Eusparassus concolor Caporiacco, 1939 is transferred to Olios and the replacement name Olios quesitio is proposed because of secondary homonymy. For the majority of the species, new geographical records are presented. The systematics and zoogeography of the currently known species and species groups are discussed. A brief note on the copulation process of E. walckenaeri is presented.

Book Description
"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 of a 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 assemblages that require relimitation"--Page 3

Book Description
ÿThe Selenopidae are a family of medium to large spiders with extremely flattened bodies. They are exceptional in that both their running and striking speeds place them amongst the world?s fastest animals. They occur in all habitable continents but are most abundant in tropical and adjacent realms. Selenopid spiders are usually found under rocks or under tree bark, and have the ability to squeeze into tight crevices. The family currently comprises around 200 species in five genera. In this monograph, four new genera and 27 new species are described from Australia and the Oriental Region, bringing the world total to nine genera and over 230 species. Several species previously placed in Selenops are transferred to the new genera. The Australian fauna is found to be more diverse than previously documented with a total of 24 species, 23 of which are new. A key to the genera of Selenopidae is provided, as are keys to the species of the new genera Karaops and Makdiops.
