DISCLAIMER — This resource was first intended as for private use of the members of the arachnology lab of Museu Nacional, but later we thought "why not to share this with the world?". Eventually if greedy lawyers (redundance...) start to bother us with copyright matters, etc, we may have to be forced to quit the project and keep this just to ourselves.
