    This work was developed in three remnants of Atlantic forest in southeastern Brazil. We aimed to assess edge effects in the spider community in a well conserved fragment and to study the variation of spider diversity among fragments of different sizes. The spider families with the highest richness were Theridiidae (38 sp), Araneidae (31 sp) and Salticidae (25 sp). The control area showed the highest diversity (D=0.98) and exclusive species (58.9%). We concluded that spider richness is higher in the large and best preserved fragment. In addition, we found that species richness and abundance increased towards the interior

    <abstract language="eng">The subfamily Anyphaeninae is revised at genera level in the Neotropical region. Anyphaeninae is diagnosed by the tracheal spiracle approximately in the midway of venter or between the midway of venter and the epigastric groove; retromargin of chelicerae with more than four denticles; and male palp with tegulum basket-like or cup-like, without the basal lightly sclerotized area. The subfamily contais 32 genera, 14 of which are new: Aljassa (type species Teudis annulipes Caporiacco), Buckupiella (type species B. imperatriz sp.n., from Brazil and Argentina), Hatitia (type species H.yhuaia sp.n., from Peru) Iguarima (type species Anyphaena censoria Keyserling), Ilocomba (type species I. marta sp.n., from Colombia), Italaman (type species I. santamarina sp.n., from Brazil, Colombia and Argentine), Jessica (type species Osoriella osoriana Mello-Leitão), Katissa (type from Jamaica), Otoniela (type species O. adisi sp.n., from Brazil), Pippuhana (type species P. gandu sp.n., from Brazil), Timbuka (type species T. boquete sp.n., from Costa Rica, Panamá and Colômbia), Umuara (type species Clubiona fasciata Blackwall), Xiruana (type species Aysha gracilipes Keyserling). Other new species and the male of Bromelina zuniala are described: Iguarima pichinha and Lepajan edwardsi from Ecuador; Temnida rosário, Umuara pydanieli and U. juquia from Brazil; Umuara junin, Hatitia conchaque from Peru; Ilcomba perija from Colombia. Twelve new synonyms are presenteei: Wuljilopsis keyserlingi soares & Camargo witn W. tenuips (Keyserling); Teudis foliatus Schmidt with Patrera ruber (F.O.P. - Cambridge); Teudis moreirae Mello-Leitão with Teudis angusticeps (Keyserling); Anyphaena rufibarbis Mello-Leitão with Jessica osoriana (Mello-Leitão); Aysha cinereoviítata Mello-Leitão with Iguarima censoria (Keyserling); Teudis bucolicus Chickering with Katissa simplicipalpis (Simon); Gayenna minutissima Petrunkevitch with Lupetíiana mordax (O.P.-Cambridge); Teudis adfabilis (Keyserling) and Teudis leucochlorus Mello-Leitão with Umuara fasciata (Blackwall); Aysha fulviceps Keyserling with Xiruana gracilipes (Keyserling); Aysha mandibularis (Keyserling) with Aljassa subpallida (L. Koch).

    Ctenus bimaculatus Taczanowski, 1874, is removed from the synonymy of Ancylometes rufus (Walkenaer, 1837) and transferred to the genus Cupiennius Simon, 1891, in which it is placed as a senior synonym of Cupiennius celerrimus Simon, 1891. New records are presented for C. bimaculatus (TACZANOWSKI 1874) and a new species, C. vodou, is described from Haiti.<br>Ctenus bimaculatus Taczanowski, 1874, é removido da sinonímia de Ancylometes rufus (Walkenaer, 1837) e transferido para o gênero Cupiennius Simon, 1891, no qual é considerado sinônimo sênior de Cupiennius celerrimus Simon, 1891.
