Effects of habitat fragmentation on the spider community (Arachnida: Araneae) in three Atlantic forest remnants in southeastern Brazil.

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

Revisão de Anyphaeninae Bertkau a nível de gêneros na Região Neotropical (Araneae, Anyphaenidae) Revision of Anyphaeninae Bertkau at genera level in the Neotropical Region (Araneae, Anyphaenidae)

<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.
