Book Description
The Afrotropical sac spider genus Messapus Simon, 1898, presently placed in the Castianeirinae, is reviewed. The type material of the type species, M. martini Simon, 1898, clearly represents two different species, a corinnine female (here designated the lectotype) and a castianeirine male (the paralectotype). The female is redescribed and its corresponding male is described for the first time. As a result, Messapus is transferred to the Corinninae. Corinna natalis Pocock, 1898 is transferred to Messapus, while Messapus secundus Strand, 1907 is transferred to Merenius Simon, 1909. The new genus Copuetta gen. nov., with the type species C. maputa sp. nov., is established to accommodate the misidentified castianeirine male paralectotype of M. martini, and its matching female is described for the first time. Castianeira kibonotensis Lessert, 1921 syn. nov. is considered a junior synonym of Copuetta lacustris (Strand, 1916) comb. nov., which is redescribed from both sexes and transferred from Copa Simon, 1885. A further eleven new species of Copuetta are described: C. comorica sp. nov., C. erecta sp. nov., C. kakamega sp. nov., C. kwamgumi sp. nov., C. lesnei sp. nov., C. litipo sp. nov., C. lotzi sp. nov., C. magna sp. nov., C. naja sp. nov., C. uzungwa sp. nov. and C. wagneri sp. nov. Of these species, only C. lacustris and C. magna sp. nov. have large distribution ranges. Seven of the species are only known from the type locality and the remaining four have distributions restricted to one or two countries. A second new genus, Wasaka gen. nov., is described for four new species with restricted distributions from East and Central Africa: W. imitatrix sp. nov., W. montana sp. nov., W. occulta sp. nov. (type species) and W. ventralis sp. nov. A first phylogenetic analysis focused on the Afrotropical Castianeirinae is presented. The results support the placement and transfer of Messapus (including M. natalis comb. nov.) and Medmassa Simon, 1887 in the Corinninae, and the monophyly of a clade including the four cryptic lycosiform castianeirine genera from the Afrotropical Region (Copa, Copuetta gen. nov., Echinax Deeleman-Reinhold, 2001 and Wasaka gen. nov.). The implications of the phylogenetic results are briefly discussed.

Book Description
The Micropholcommatidae are a family of tiny, distinctive araneoid spiders, known from southern-temperate habitats throughout Australasia and Chile. The greatest abundance of individuals and the largest diversity of taxa occur in the cool-temperate rainforests of south-eastern Australia and New Zealand, where micropholcommatid spiders can be very common within moss and leaf litter microhabitats. Although poorly studied biologically and largely neglected taxonomically, the Micropholcommatidae are a diverse lineage, with a significantÿ The monograph in this volume presents a complete generic-level revision of the spider family Micropholcommatidae. The phylogenetic position and internal phylogeny of the family are tested with two separate morphological cladistic analyses, the results of which inform a comprehensive generic-level classification. In total, 26 new species, 12 new genera, one new tribe and two new subfamilies are described, taking the total documented micropholcommatid fauna to 58 species. The distribution and Gondwanan biogeography of the family are also discussed, and natural history information is provided where known. Most importantly, the results of this paper present a taxonomic framework and a phylogenetic foundation for all future research on the Micropholcommatidae; a template by which new species can be described and existing species can be identified, and a valuable dataset for exploring phylogenetic hypotheses.

Book Description
The Neotropical genus Acrochaeta Wiedemann is revised and a cladistics analysis of the genus based on morphological characters is presented. This paper raises the total number of extant Acrochaeta species from 10 to 14 with the description of nine new species, the synonymy of one species, the transfer of five species to other genera and the transfer of one species of Merosargus to Acrochaeta. The new species described (of which eight are from Brazil and one from Bolivia and Peru) are Acrochaeta asapha nov. sp., A. balbii nov. sp., A. dichrostyla nov. sp., A. polychaeta nov. sp., A. pseudofasciatanov. sp., A. pseudopolychaeta nov. sp., A. rhombostyla nov. sp. A. ruschii nov. sp. and A. stigmata nov. sp. The primarytypes of all Acrochaeta species were studied at least from photos, when possible with the study of dissected male or female terminalia. A. mexicana Lindner is proposed as a junior synonym of A. flaveola Bigot. M. chalconota (Brauer) comb. nov., M. degenerata (Lindner) comb. nov., M. longiventris (Enderlein) comb. nov. and M. picta (Brauer) comb. nov. are herein transferred from Acrochaeta to Merosargus Loew, and Chrysochlorina elegans (Perty) comb. nov. is transferred from Acrochaeta to Chrysochlorina James. A. convexifrons (McFadden) comb. nov. is transferred from Merosargus to Acrochaeta. The limits of the genus and its insertion in the Sarginae are considered, and an updated generic diagnosis is provided. All species of the genus are redescribed and diagnosed, and illustrated with photos of the habitus, thorax, wing, and drawings of the antenna and male and female terminalia. Distribution maps are provided for the species, along with an identification key for adults of all species. Parsimony analyses were carried out under equal and implied weight. Our matrix includes 43 terminal taxa - of which 26 are outgroup species from four different sargine genera - and 59 adult morphological characters. The phylogenetic analysis supports the monophyly of Acrochaeta based on features of the head, thorax and abdomen. An inner clade (Acrochaeta flaveola species group) within the genus was clearly recovered based on characters of male and female terminalia. There is good evidence for the paraphyly of Merosargus with Acrochaeta as a subclade, demanding a wider study of the subfamily for a sound solution for the genus Merosargus.

Book Description
We review the spider genus Oxysoma Nicolet, with most of its species endemic from the southern temperate forests in Chile and Argentina, and present a phylogenetic analysis including seven species, of which three are newly described in this study (O. macrocuspis new species, O. kuni new species, and O. losruiles new species, all from Chile), together with other 107 representatives of Anyphaenidae. New geographical records and distribution maps are provided for all species, with illustrations and reviewed diagnoses for the genus and the four previously known species (O. punctatum Nicolet, O. saccatum (Tullgren), O. longiventre (Nicolet) and O. itambezinho Ramírez). The phylogenetic analysis using cladistic methods is based on 264 previously defined characters plus one character that arises from this study. The three new species are closely related with Oxysoma longiventre, and this four species compose what we define as the Oxysoma longiventrespecies group. The phylogenetic analysis did not retrieve the monophyly of Oxysoma, which should be reevaluated in the future, together with the genus Tasata.

Book Description
The genus Smeringopina Kraus, 1957 is revised, with redescriptions of the nine previously known species and descriptions of 35 new species. Smeringopina is largely restricted to the tropical forests of West and Central Africa. It includes both large species that build their domed sheet-webs in protected spaces near the ground, and small (probably derived) litter-dwelling species. With leg spans up to 18 cm the former group includes some of the largest pholcids known. A first cladistic analysis of Smeringopina, based on 68 morphological (including SEM) characters, suggests several well-defined species groups but also identifies some problematic species whose phylogenetic position needs further study. The 'Dahomey- Gap' separates two small western clades (the guineensis species group and two species of the ankasa group) from all other species. The following new species are described: S. ankasa; S. attuleh; S. bamenda; S. bayaka; S. belinga; S. bioko; S. bomfobiri; S. bwiti; S. chaillu; S. djidji; S. ebolowa; S. essotah; S. etome; S. fang; S. fon; S. ibadan; S. iboga; S. kala; S. kikongo; S. kinguele; S. kribi; S. lekoni; S. luki; S. mayebout; S. mbouda; S. mohoba; S. moudouma; S. ndjole; S. ngungu; S. nyasoso; S. ogooue; S. sahoue; S. simintang; S. tchimbele; S. tebe.

Book Description
Elaver O. Pickard-Cambridge, 1898 is characterized and redescribed, including 49 species occurring from the United States to Argentina. Thirty seven previously known species are redescribed: Elaver achuca (Roddy, 1966) revalidated, E. balboae (Chickering, 1937), E. barroana (Chickering, 1937), E. calcarata (Kraus, 1955), E. carlota (Bryant, 1940), E. chisosa (Roddy, 1966), E. crinophora (Franganillo, 1934), E. crocota (O. Pickard-Cambridge, 1896), E. albicans(Franganillo, 1930) name restored, E. depuncta O. Pickard-Cambridge, 1898, E. elaver (Bryant, 1940), E. excepta (L. Koch, 1866), E. grandivulva (Mello-Leitão, 1930), E. hortoni (Chickering, 1937), E. implicata (Gertsch, 1941), E. juana(Bryant, 1940), E. kohlsi (Gertsch & Jellison, 1939), E. linguata (F.O. Pickard-Cambridge, 1900), E. madera (Roddy, 1966), E. mirabilis (O. Pickard-Cambridge, 1896) new. comb., E. mulaiki (Gertsch, 1935), E. multinotata (Chickering, 1937), E. orvillei (Chickering, 1937), E. placida O. Pickard-Cambridge, 1898, E. portoricensis (Petrunkevitch, 1930), E. quadrata (Kraus, 1955), E. richardi (Gertsch, 1941), E. sericea O. Pickard-Cambridge, 1898, E. sigillata (Petrunkevitch, 1925), E. simplex (O. Pickard-Cambridge, 1896), E. texana (Gertsch, 1933), E. tigrina O. Pickard-Cambridge, 1898 namerestored, E. tricuspis (F.O. Pickard-Cambridge, 1900), E. tristani (Banks, 1909), E. tumivulva (Banks, 1909), E. valvula(F.O. Pickard-Cambridge, 1900) and E. wheeleri (Roewer, 1933). Ten new species are described: E. candelaria n. sp. andE. helenae n. sp. from Mexico; E. arawakan n. sp. from Haiti; E. lizae n. sp. from Costa Rica; E. darwichi n. sp. fromEcuador; E. juruti n. sp., E. tourinhoae n. sp. and E. vieirae n. sp. from Brazil; E. shinguito n. sp. from Peru and E. beni n. sp. from Bolivia. The female of E. hortoni is described for the first time. Lectotypes are designated for E. sigillata and its actual female is described for the first time. Four new synonyms are proposed: E. languida (Gertsch, 1941) is synonimized with E. multinotata; E. dorothea (Gertsch, 1935) with E. wheeleri; E. exempta (Gertsch & Davis, 1940) with E. placida and E. vulnerata (Kraus, 1955) with E. calcarata. The drawings in the original descriptions of E. kawitpaaia (Barrion & Litsinger, 1995) and E. turongdaliriana (Barrion & Litsinger, 1995) are sufficiently informative to exclude these species from Elaver but not to accurately establish its generic affiliation. Thus, until the types become available for examination, these species must remain as Clubionidae incertae sedis. Heterochemmis (F.O. Pickard-Cambridge, 1900) is synonymized with Elaver and Heterochemmis mutatus Gertsch & Davis,1940 is recognized as a junior synonym of Elaver mirabilis n. comb., the type species of Heterochemmis. New records are presented for E. valvula, E. balboae, E. brevipes(Keyserling, 1891), E. grandivulva and E. lutescens (Schmidt, 1971). Two species described by Franganillo, E. tenera(Franganillo, 1935) and E. tenuis (Franganillo, 1935), are considered species inquirendae.
