Abstract
In this study, the Gasteruptiidae (Hymenoptera, Evanioidea) collected in three environments at the Department of Rocha, in Eastern Uruguay, were documented based on a survey carried out with Malaise traps between December 2014 and December 2016. During the samplings, four species of Gasteruption Latreille, 1796 were captured, being 14 females and three males of Gasteruption brachychaetun Schrottky, 1906; eight females and five males of Gasteruption brasiliense (Blanchard, 1840); one female of Gasteruption helenae Macedo, 2011 and one female of Gasteruption brandaoi Macedo, 2011. Gasteruption brachychaetun, G. helenae and G. brandaoi are recorded by the first time from Uruguay.

The only Gasteruptiidae species ever recorded in Uruguay was Gasteruption brasiliense (Blanchard, 1840), with only one female collected in 1963 in the central-north of the country (Macedo 2011)
This study resulted in the capture of 17 specimens of Gasteruption brachychaetun Schrottky, 1906 (14 females, 3 males), 13 of Gasteruption brasiliense (Blanchard, 1840) (8 females, 5 males), one female of Gasteruption brandaoi
