Two new humicolous micro-buthid species belonging to the genus Microananteris Lourenço, 2003 are described from French Guiana. The descriptions are based on two adult specimens collected in organic soil with the use of extraction by the Berlese method. The new discoveries bring further support to the validity of the genus Microananteris. The geographic distribution of the known species of Microananteris remains limited to the only territory of French Guiana.
