AbstractHersiliidae Thorell is a family of conspicuously long-legged spiders, characterized by extremely elongate posterior lateral spinnerets. To date, it includes 148 species distributed within seven genera, of which Tama Simon is the only one recorded in the Neotropical Region. Of the 23 known Tama species, 18 are exclusively Neotropical. In order to enhance the scientific knowledge on the family and its members this study presents a cladistic analysis and a taxonomic revision of the Neotropical and Nearctic hersilids. The cladistic analysis places the Neotropical and Neartic species in two separate clades, none of which are closely related to the genus Tama. Based on this result, Tama mexicana (O.P.-Cambridge) and T. forcipata (F.O.P.-Cambridge) are transferred to Neotama and three new genera are proposed to include the remaining species: Ypypuera n. gen. to include T. crucifera Vellard and T. vittata (Simon); Iviraiva n. gen. to include T. pachyura Mello-Leitão and T. argentina Mello-Leitão; and Yabisi n. gen to include T. habanensis Franganillo. Based on the taxonomic revision, eight synonymies are proposed: Tama crulsi Mello-Leitão, Tama micrura Mello-Leitão and T. occidentalis Schenkel with Ypypuera crucifera (Vellard); T. brasiliensis Piza and T. karinae Carcavallo with I. pachyura (Mello-Leitão); T. catamarcaensis Carcavallo and T. longipes Carcavallo with I. argentina (Mello-Leitão); and T. guianensis Mello-Leitão with Neotama mexicana (O.P.-Cambridge); three names are placed as nomina dubia: Tama americana (Simon), T. albigastra Mello-Leitão and T. sasaimae Mello-Leitão and four new species are described: Neotama cunhabebe, from São Paulo, Brazil, Neotama obatala, from Bahia, Brazil, Ypypuera esquisita, from Quevedo, Ecuador, and Yabisi guaba, from Pedernales, Dominican Republic. The family Hersiliidae, the genus Neotama and all three new genera, as well as all Neotropical and Nearctic species are redescribed and diagnosed and a identification key is presented.

The cryptic assassin bug subfamily Physoderinae is characterized by a distinctly uneven species and genus-level diversity across continents, but the lack of a phylogeny has so far precluded investigations into the biogeographic history of the group. Endemic Madagascan Physoderinae (11 of the 15 genera) exhibit broad morphological diversity, but the large (38 spp.) and seemingly uniform genus Physoderes is widely distributed across the Oriental and Australasian regions. The three remaining genera are small or even monotypic and restricted to the Neotropical (Cryptophysoderes, Leptophysoderes) and Afrotropical (Porcelloderes) regions. To investigate relationships among Physoderinae, with emphasis on the monophyly of the Madagascan fauna and the monophyly of Physoderes, we conducted a cladistic analysis based on 57 morphological characters and complete genus-level taxon sampling. We found that the Madagascan fauna is not monophyletic, indicating that the island was colonized more than once, although the great majority of Madagascan taxa are part of a single clade. Overall relationships are recovered as Afrotropical Porcelloderes + [(Neotropical Cryptophysoderes, Leptophysoderes) + (Madagascan, Oriental and Australasian taxa)]. Physoderes is shown to be polyphyletic and 3 new genera, Breviphysoderes gen. nov., Macrophysoderes gen. nov. and Nanophysoderes gen. nov., are erected to accommodate new species and several species previously classified as Physoderes. A taxonomic revision of Physoderes and allied genera is conducted. Diagnoses, updated distribution ranges, habitus and genitalic images, and identification keys are provided. A total of 17 synonymies are given, and 15 new species and 3 new genera are described, focusing on the diversity of Physoderinae in the Oriental and Australasian regions. The new species are Breviphysoderes fulvopicta gen. et sp. nov., B. tenebrosa gen. et sp. nov., Macrophysoderes cirripilosa gen. et sp. nov., M. elongata gen. et sp. nov., M. finisterre gen. et sp. nov., M. grandis gen. et sp. nov., Paraphysoderes popeye sp. nov., Physoderes anamalaiensis sp. nov., P. brevipennis sp. nov., P. minime sp. nov., P. muluensis sp. nov., P. mysorensis sp. nov., P. nigripennis sp. nov., P. ractepilosa sp. nov. and P. tricolor sp. nov.

PionosyllisMalmgren, 1867 is revised based on a cladistic analysis of the 41 species considered herein as valid, two newly described species in this paper (Basidiosyllis victoriaeandOpisthodonta russelli), 11 species from other genera actually belonging, or related to,Pionosyllis, and 13 syllid species from different subfamilies. The phylogenetic analysis is based on 55 characters; a strict consensus of 1200 equally parsimonious trees (length = 314 steps) was obtained. The clades containing species usually included withinPionosyllisare newly named within the frame of a new Linnean classification of the group (except for one, belonging to another subfamily). The diagnosis ofPionosyllisis emended, and five new genera are proposed:Synmerosyllis,Basidiosyllis,Westheidesyllis,PerkinsyllisandBrevicirrosyllis.ParaehlersiaSan Martín, 2003, proved to be closely related toPionosyllis. Seven species are transferred toOpisthodontaLangerhans, 1879, here emended, and three transferred toNudisyllisKnox & Cameron, 1970 (according to San Martín & Hutchings, 2006).Opisthodonta uraga(Imajima, 1966) comb. nov. andPerkinsyllis longisetosacomb. nov. are redescribed.Pionosyllis compactaMalmgren, 1867,P. styliferaEhlers, 1913,P. giganteaMoore, 1908,P. enigmatica(Wesenberg-Lund, 1950), andNudisyllis magnidens(Day, 1953) comb. nov., are redescribed.Pionosyllis marquesensisMonro, 1939 andP. proceraHartman, 1965 likely belong to the Syllinae, thus they are not treated in the taxonomic account.

The subfamily Rhynchoproctinae is revised at the generic level. Four new genera and a remarkable new species are described: Alienostreptus, gen. nov. from Vietnam, Armatostreptus, gen. nov., Heptischius, gen. nov., and Heptischius lactuca, sp. nov. from Thailand, and Prominulostreptus, gen. nov. from China. Agaricogonopus Zhang & Zhang, 1997, is removed from synonymy with Junceustreptus Demange, 1961. All 14 genera of the subfamily share three diagnostic gonopodal characters: the posterior surface of the anterior coxal fold forms a deep concavity, there is a mesal flap on the gonopod coxa, and the posterior coxal fold is very low. A cladistic analysis based on morphological data supports monophyly of Rhynchoproctinae and the distincness of the newly described genera. A dichotomous key to the genera is included.

This study examines the phylogeny, taxonomy, distribution and biology of the gasteruptiid subfamily Hyptiogastrinae and, at the same time, presents an overview of the family. Following a cladistic analysis of 35 discrete morphological characters, two monophyletic genera are recognised, Hyptiogaster Kieffer and Pseudofoenus s. l. Kieffer. As a consequence, the genera Aulacofoenus Kieffer, Crassifoenus Crosskey, and Eufoenus Szépligeti are synonymised with Pseudofoenus. A total of 88 species are recognised for the subfamily, 10 species of Hyptiogaster, which are restricted to mainland Australia, and 78 species of Pseudofoenus, 40 of which are described as new. Pseudofoenus has a restricted Gondwanan distribution and is found in Australia including Tasmania (65 spp.), New Guinea and New Britain (5 spp.), the south-west Pacific (New Caledonia, New Hebrides and Fiji – 2 spp.), New Zealand (4 spp.) and South America (2 spp.). No new species have been recorded from either New Zealand or South America. For Pseudofoenus, information on the distribution of each species, their biology (if known) and an identification key are presented.Following a taxonomic revision, the following new species are described: P. baileyi, sp. nov., P. baitetaensis, sp. nov., P. beverlyae, sp. nov., P. caperatus, sp. nov., P. cardaleae, sp. nov., P. carrabinensis, sp. nov., P. claireae, sp. nov., P. collessi, sp. nov., P. coorowensis, sp. nov., P. crosskeyi, sp. nov., P. douglasorum, sp. nov., P. eliseae, sp. nov., P. ericae, sp. nov., P. eustonensis, sp. nov., P. feckneri, sp. nov., P. gressitti, sp. nov., P. gullanae, sp. nov., P. hackeri, sp. nov., P. imbricatus, sp. nov., P. iqbali, sp. nov., P. kadowi, sp. nov., P. karimuiensis, sp. nov., P. kelleri, sp. nov., P. leinsterensis, sp. nov., P. macdonaldi, sp. nov., P. malkini, sp. nov., P. marshalli, sp. nov., P. masneri, sp. nov., P. mitchellae, sp. nov., P. morganensis, sp. nov., P. nalbarraensis, sp. nov., P. pumilis, sp. nov., P. schmidti, sp. nov., P. stevensi, sp. nov., P. tasmaniensis, sp. nov., P. taylori, sp. nov., P. umboiensis, sp. nov., P. walkeri, sp. nov. and P. zborowskii, sp. nov. The synonymy of Aulacofoenus, Crassifoenus and Eufoenus with Pseudofoenus result in the following new combinations: from Aulacofoenus: P. bungeyi (Jennings & Austin), comb. nov., P. deletangi (Schletterer), comb. nov., P. fallax (Schletterer), comb. nov., P. fletcheri (Jennings & Austin), comb. nov., P. goonooensis (Jennings & Austin), comb. nov., P. infumatus (Schletterer), comb. nov., P. kurmondi (Jennings & Austin), comb. nov., P. loxleyi (Jennings & Austin), comb. nov., P. marionae (Jennings & Austin), comb. nov., P. perenjorii (Jennings & Austin), comb. nov., P. swani (Jennings & Austin), comb. nov., P. thoracicus (Guérin Menéville), comb. nov., P. whiani (Jennings & Austin), comb. nov. and P. wubinensis (Jennings & Austin), comb. nov.; from Crassifoenus: P. houstoni (Jennings & Austin), comb. nov., P. grossitarsis (Kieffer), comb. nov and P. macronyx (Schletterer), comb. nov.; and from Eufoenus: P. antennalis (Schletterer), comb. nov., P. australis (Westwood), comb. nov., P. crassitarsis (Kieffer), comb. nov., P. darwini (Westwood), comb. nov., P. extraneus (Turner), comb. nov., P. ferrugineus (Crosskey), comb. nov., P. floricolus (Turner), comb. nov., P. inaequalis (Turner), comb. nov., P. melanopleurus (Crosskey), comb. nov., P. minimus (Turner), comb. nov., P. nitidiusculus (Turner), comb. nov., P. patellatus (Westwood), comb. nov., P. pilosus (Kieffer), comb. nov., P. reticulatus (Crosskey), comb. nov., P. rieki (Crosskey), comb. nov., P. ritae (Cheesman), comb. nov. and P. spinitarsis (Westwood), comb. nov.

A taxonomic revision of the subgenus Chthonius (Ephippiochthonius) in the Iberian Peninsula, Balearic Islands and    Macaronesia is presented. New and previously insufficiently studied characteristics are shown to be taxonomically useful, such as the chelal lyrifissures patterns, chaetotaxy and condylar complex. Three taxa previously treated as subgenera of Chthonius are here raised to generic rank: Ephippiochthonius n. stat., Globochthonius n. stat., and Hesperochthonius n. stat. Two new genera are described: Cantabrochthonius n. gen. and Occidenchthonius n. gen. Thirty-five new species are described: Ephippiochthonius aini n. sp., E. andalucia n. sp., E. aurouxi n. sp., E. benimaquia n. sp., E. caceresi n. sp., E. castellonensis n. sp., E. comasi n. sp., E. fadriquei n. sp., E. galcerani n. sp., E. gonzalezi n. sp., E. henderickxi n. sp., E. ibiza n. sp., E. masoae n. sp., E. portugalensis n. sp., E. riberai n. sp., E. serengei n. sp., E. sevai n. sp., E. tarraconensis n. sp., E. vicenae n. sp., E. zaballosi n. sp., Occidenchthonius anae n. sp., O. beieri n. sp., O. ebo n. sp., O. felgueraorum n. sp., O. gardinii n. sp., O. hoerwegi n. sp., O. lencinai n. sp., O. mahnerti n. sp., O. mateui n. sp., O. montagudi n. sp., O. murcia n. sp., O. oromii n. sp., O. ortunoi n. sp., O. riopar n. sp. and O. serranoi n. sp. A neotype is designated for Ephippiochthonius catalonicus (Beier, 1939), n. comb. As result of the changes in generic rank, 45 new combinations for species are proposed.

The Pararchaeidae, a family of cryptic spiders known only from Australia and New Zealand, is revised. Six new genera: Anarchaea, gen. nov., Flavarchaea, gen. nov., Forstrarchaea, gen. nov., Nanarchaea, gen. nov., Ozarchaea, gen. nov., Westrarchaea, gen. nov., and 24 new species are described, 23 from mainland Australia and one from New Zealand. Anarchaea, gen. nov. from eastern Australia contains four species: A. corticola (Hickman, 1969), comb. nov. (type species), A. falcata, sp. nov., A. raveni, sp. nov. and A. robusta (Rix, 2005), comb. nov. Flavarchaea from eastern, southern and south-western Australia contains seven species: F. anzac, sp. nov., F. badja, sp. nov., F. barmah, sp. nov., F. hickmani (Rix, 2005), comb. nov., F. lofty, sp. nov., F. lulu (Rix, 2005), comb. nov. (type species) and F. stirlingensis, sp. nov. Forstrarchaea is represented only by the type species F. rubra (Forster, 1949), comb. nov. from New Zealand. Nanarchaea from eastern Australia contains two species: N. bryophila (Hickman, 1969), comb. nov. and N. binnaburra (Forster, 1955), comb. nov. (type species). Ozarchaea from Australia and New Zealand contains 16 species: O. bodalla, sp. nov., O. bondi, sp. nov., O. daviesae, sp. nov., O. forsteri, sp. nov., O. harveyi, sp. nov., O. janineae, sp. nov., O. ornata (Hickman, 1969), comb. nov.

Pararchaea Forster, 1955 is represented only by the type species P. alba Forster, 1955 from New Zealand. Westrarchaea, endemic to south-western Western Australia, contains three species: W. pusilla, sp. nov., W. sinuosa, sp. nov. (type species) and W. spinosa, sp. nov. A morphological cladistic analysis of the Pararchaeidae supported monophyly of the genera. Natural history information is summarised for each species where known, and the moulting behaviour, mating behaviour and egg sac of a pararchaeid species are described for the first time.
