Abstract
The family Baetidae is still poorly known from Venezuela, particularly in the South of this country. Three field trips were carried out in La Gran Sabana region (Bolivar State). As a result of these trips, four genera {Cryptonympha, Harpagobae-tis, Spiritiops and Zelusid) and nine species are reported for the first time from this region. A discussion of each taxon is included as well as drawings when it is necessary. Keys with all known genera of Baetidae and all known species of Cam-elobaetidius from Venezuela are included too. With this analysis, the number of the genera and species reported is duplicated improving the knowledge of this family from this country.
