Arachnida at "Reserva Ducke", Central Amazonia/Brazil
Data show, that almost one-fourth of the families presently known in the Arachnida and about 2% of the worlds described species are represented in Amazonia. Expand
Extreme degree of chromosome number variability in species of the spider genus Scytodes (Araneae, Haplogynae, Scytodidae)
This paper aims to demonstrate the efforts towards in-situ applicability of EMMARM, as to provide real-time information about concrete mechanical properties such as E-modulus and compressive strength. Expand
Two new species of litter-dwelling Metagonia spiders (Araneae, Pholcidae) document both rapid and slow genital evolution
It is claimed that relatively rapid evolution of genitalia may often be restricted to the shapes, numbers, and sizes of individual structures, and the more basic pattern, including the presence or absence of structures and their interrelationships, does not seem to evolve more rapidly than other aspects of morphology.

The Brazilian Goblin Spiders of the New Genus Predatoroonops (Araneae: Oonopidae)
The new endemic goblin spider genus Predatoroonops is erected for 17 new soft-bodied oonopid species from Brazil, and the type species, P. schwarzeneggeri, sp. Expand
A contribution to the knowledge of the spider fauna (Arachnida: Araneae) of the floodplain forests of the main Amazon River channel.
We collected spiders during an expedition along 3000 km of the floodplains of the Brazilian part of the main channel of the Amazon River and identified them to family, genus and species /Expand
Revision and cladistic analysis of the spider family Hersiliidae (Arachnida, Araneae) with emphasis on Neotropical and Nearctic species
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. Expand
The Brazilian Goblin Spiders of the New Genus Guaraguaoonops (Araneae: Oonopidae)
ABSTRACT A new endemic goblin spider genus Guaraguaoonops is erected to include two new soft-bodied oonopid species from Brazil: the type species, G. hemhem, distributed in the states of Maranhão,Expand
Diversity and endemism of pholcid spiders in Brazil's Atlantic Forest, with descriptions of four new species of the Atlantic Forest endemic genus Tupigea (Araneae: Pholcidae)
An effort to collect all pholcid spider species at six localities in the Serra do Mar region of the Brazilian Atlantic Forest shows that all but one locality produced 11–15 species, compared with published and unpublished species counts worldwide. Expand
How not to delimit taxa: a critique on a recently proposed "pragmatic classification" of jumping spiders (Arthropoda: Arachnida: Araneae: Salticidae).
The main goal of the ICZN is to promote stability and universality in the scientific names of animals and to ensure that the name of each taxon is unique and distinct. Expand
