The Dermaptera of the northern part of South America have been little studied. The Dermaptera fauna of Columbia and Ecuador to the east of this region has been investigated to some extent, but records of this order from the western countries are very sparse indeed. Prior to BOESEMAN (1954) only two species were known from Surinam, whilst 10 species have been recorded from Guyana, and 13 species from French Guiana. These totals obviously represent only a very small proportion of the true fauna, and BOESEMAN (1954) recorded a further 9 species from Surinam, so bringing the total known species from all the Guyanas to 26.
