The scorpions from the Mitaraka Massif in French Guiana (Scorpiones: Buthidae, Chactidae)

A synopsis is proposed for all scorpion species collected, up to present, in the Mitaraka Massif in French Guiana, a site located near to the borders of French Guiana, Brazil and Suriname. One new species, Guyanochactas touroulti n. sp. (Chactidae) is described. The description of the new species brings further evidence to the biogeographic pattern of distribution presented by some elements of the family Chactidae endemic to the Tepuys or the Inselberg formations of South America.
