Nine new species of spiders have been discovered by Brazilian scientists, providing a new example of the rich biodiversity of the Amazon river basin, a researcher said Monday.

"While one or two of the newly described species were found in central Brazil, seven of them were identified in the Amazon," said Antonio Brescovit of the Butatan Institute in Sao Paulo.

A team of researchers from the institute and the Emilio Goeldi museum in Belem discovered the new species during the first half of 2005.

The most recently discovered of the nine, Ericaella florezi, was related to other Latin American species but developed into a unique spider when separated by the geological rise of the Andes mountains range, some 12 million years ago, according to Brescovit.

The seven found in the Para region of the Amazon include a type of Scytodes spider, and six new species of the genus Attacobius.

In a step that advances our ability to discern the ancient evolutionary relationships between different genes and their biological functions, researchers have provided insight into the present-day outcome of a single gene duplication that occurred over a hundred million years ago in an ancestor of modern plants.
