Summary

A new species of scorpion belonging to the genus Spinochactas Lourenço, 2016 (Chactidae) is described from the commune of Camopi, located close to the Eastern border of French Guiana with Brazil. The new species, Spinochactas camopi n. sp., is the second species belonging to the genus Spinochactas found in French Guiana, which remains endemic to this French overseas department. The description of the new species brings further evidence to the validity of the genus Spinochactas and to its biogeographic pattern of distribution which is now confirmed both for Inselberg formations and lowland rainforests of French Guiana. With the description of this new species, the number of known scorpion species occurring in French Guiana is increased to 40, of which 31 are endemic.
