Vanchoniochactas roraima Lourenco & Duhem, 2009 (Chactidae)

Abstract:
A new species, Vachoniochactas roraima sp. n. (Chactidae) is described from Mount Roraima, a site located on the borders of Brazil, Guyana and Venezuela. The description of the new species brings further evidence to the biogeographic pattern of distribution presented by the genus Vachoniochactas, as an endemic element to the Tepuys formations of South America.
