Feeding Frequency, Prey Acceptance, and Natural Diet of the Mygalomorph Spider Goloboff 1995 (Araneae: Nemesiidae).

The family Nemesiidae is the second most diverse family of Mygalomorphae spiders. (Nemesiidae) is commonly found in hilly areas of central Argentina. These spiders are considered generalists due to their basal position in the phylogeny, but little is known about the trophic ecology of the species.

Species conservation profile of the rare and endemic trapdoor spider (Araneae, Migidae) from Central Argentina.

Background: Schiapelli & Gerschman 1975 is the only species of Migidae in Argentina. It is a rare and endemic spider only found in relict grassland of mountain systems in the province of Buenos Aires. This species is a habitat specialist spider occupying specific areas with certain microclimatic conditions on hilly and rocky grassland areas at about 500-1500 meters above sea level.

On the taxonomy of southern South American species of the wolf spider genus (Araneae: Lycosidae: Allocosinae).

Three species of the genus Allocosa Banks, 1900 from southern South America are redescribed: Allocosa alticeps (Mello-Leitão, 1944), A. brasiliensis (Petrunkevitch, 1910) and A. senex (Mello-Leitão, 1945).

A new species of Losdolobus Platnick & Brescovit 1994 (Araneae: Orsolobidae) from Argentina with notes on its ecology and distribution.

A new species of Losdolobus, L. nelsoni sp. nov.

On the ecology of the cursorial spider Odo bruchi (Araneae: Zoridae) in a grassland natural reserve from central Argentina.

The "Ernesto Tornquist" Provincial Park (ETPP) is located inside the Ventania system (Argentina) and was created to protect one of the last relicts of pampean grasslands. Even though many studies have looked at the vertebrate faunal diversity, biology, and conservation in this Park, few studies have been dedicated to arthropods. Among these, spiders have been used as ecological indicators to evaluate nature conservation status, nevertheless, basic information on their distribution and ecology is necessary for their use as indicator taxa in this region.

Mygalomorph spider community of a natural reserve in a hilly system in central Argentina.

The diversity, abundance, spatial distribution, and phenology of the mygalomorph spider community in the "Ernesto Tornquist" Strict Nature Reserve were analyzed in this study. Located in southwestern Buenos Aires, Argentina, the Reserve is representative of the Ventania system, which is a sigmoidal mountain belt 180 km in length. This exceptional hilly ecosystem is home for many endemic species and rich native fauna and flora.
