Hersiliidae 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 spider genus Peucetia includes 54 species of medium-sized and widely distributed spiders. The majority of its species occurs in the tropical regions, of which only the African fauna has been recently revised. In the Neotropical Region 26 species were described, of which 17 are here synonymyzed. Peucetia tranquillini Mello-Leitão 1922, P. rubrigastra Mello-Leitão 1929, P. meridionalis Mello-Leitão 1929, P. villosa Mello-Leitão 1929, and P. viridisternis Mello-Leitão 1945 are considered junior synonyms of P. flava Keyserling 1877. Eight names, Peucetia similis Keyserling 1877, P. amazonica Mello-Leitão 1929, P. heterochroma Mello-Leitão 1929, P. maculipedes Piza 1938, P. trivittata Mello-Leitão 1940, P. duplovittata Mello-Leitão 1941, and P. roseonigra Mello-Leitão 1943 and Tapinillus argentinus Mello-Leitão 1941 are considered junior synonyms of P. rubrolineata Keyserling 1877. Both senior species are extremelly common, occurring from Colombia to northern Argentina. Peucetia macroglossa Mello-Leitão 1929, recorded only from Central Brazilian Amazonia and Guyana is considered a senior synonym of P. melloleitaoi Caporiacco 1947. Two species occur from Southern USA to northern Colombia: Peucetia viridans (Hentz 1832) and P. longipalpis F. O. P.-Cambridge 1902. The former is recognized as a senior synonym of P. poeyi (Lucas 1857), P. bibranchiata F. O. P.- 1902 and P. rubricapilla Petrunkevitch 1925 and the later as a senior synonym of P. cauca Lourenço 1990. Peucetia viridis (Blackwall 1858), known from Africa, southern Spain and Middle East is newly recorded from the West Indies. One new species, Peucetia cayapa sp. n., is described and illustrated based on males and females from Ecuador and Peru. Peucetia caldensis Garcia-Neto 1989, from Brazil, is transferred to Tapinillus Simon 1898. The type specimens of three species, P. quadrilineata Simon 1891 and P. thalassina (C. L. Koch 1847) from Central America, and P. smaragdina Mello-Leitão 1941 from Colombia are probably lost. Since their original descriptions are not sufficiently clear for their recognition, they are considered nomina dubia.

The spider genus Ancylometes Bertkau, 1880 is revised. A. vulpes Bertkau, 1880, type species of the genus, is considered a junior subjective synonym of Dolomedes concolor Perty, 1833. Both types are lost and we redescribe the species based on specimens similar to those found at the type locality of A. vulpes. Spiders of the genus are large nocturnal ground-living hunting spiders with a strong affinity in most species, to water bodies within their tropical environment. Those species hunt also on small vertebrates like frogs, tadpoles and fishes. All species show slight sexual dimorphism in colour and body-to-leg-size relations. Females carry brown egg-sacs in chelicerae and build a nursery web. The genus is morphologically diagnosed by the presence of ventral spines on tarsi III and IV in both sexes and by their genital characters: filiform embolus with a basal membranous lobe, wing-like conductor and hammer-like median apophysis in males; female epigyne consisting of two broad lateral plates and a central plate in form of a bike saddle with its nose pointing posteriorly. Ten valid species are recognized and described, five of them are new: Ancylometes japura, A. jau, A. riparius from Amazonas, A. terrenus from Acre, Amazonas and Mato Grosso and A. pantanal from Matto Grosso do Sul, all from Brazil. The female of A. amazonicus is described for the first time and the female of A. hewitsoni for the first time based on an adult specimen. Ancylometes vulpes Bertkau, Ctenus argentinus Holmberg, Ancylometes bolivianus Tullgren, Lycoctenus bahiensis Strand, Lycoctenus selenkae Strand, Lycoctenus paraguayensis Strand, Cupiennius argentinus Petrunkevitch, Ctenus paulensis Mello-Leitão, Cupiennius diplocellatus Mello-Leitão, Ctenus originalis Mello-Leitão, Ctenus iophorus Mello-Leitão, Corinoctenus anomalostomus Mello-Leitão, Ctenus infelix (Mello-Leitão, Ctenus metatarsalis Mello-Leitão, Phoneutria niveobarbata Mello-Leitão and Corinoctenus greenwayi Carcavallo & Martinez are newly synonymized with A. concolor (Perty). Ctenus fuscus Walckenaer, Ctenus giganteus Taczanowski, Ctenus bimaculatus Taczanowski, Leptoctenus tenkatei Hasselt, Lycoctenus brunneus Pickard-Cambridge, Lycoctenus gigas Pickard-Cambridge, Lycoctenus demerarensis Pickard-Cambridge, Lycoctenus saraensis Strand, Lycoctenus paraensis Strand, Ancylometes pindareensis Mello-Leitão, Ancylometes pindareannus Mello-Leitão, Ctenus juruensis Mello-Leitão, Ctenus striolatus Mello-Leitão, Ctenus xerophilus Mello-Leitão and Lycoctenus titanus Caporiacco are newly synonymized with A. rufus (Walckenaer). Lycoctenus palustris Pickard-Cambridge, Ancylometes orinocensis Simon, Lycoctenus venezuelensis Strand, Lycoctenus caracasensis Strand and Ctenus nasutus Kraus are newly synonymized with A. bogotensis (Keyserling). A. valentinei Petrunkevitch, 1925 from Panama is a Cupiennius (new combination) and considered a senior synonym of C. panamensis Lachmuth et al., 1985. The geographical distribution is Neotropical, with one northern widespread species (A. bogotensis) reaching Central America, one widespread species of the Amazon reaching the São Paulo coastal area and one widespread species of central Brazil reaching Argentina. From the Amazon region six rarely collected species are described and one species was recently collected in the Pantanal of Brazil. (AU)

The spider genus Dossenus Simon, 1898, with six species, is revised. The types of Dossenus marginatus Simon, 1898 are redescribed. One new species, D. guapore from Mato Grosso, Brazil, is described and illustrated. The types of D. fluminensis (Mello-Leitão), D. marginellus Badcock, D. longipes Mello-Leitão and D. fidelis Mello-Leitão are juveniles and those names are therefore considered species inquirendae
