The Entomological Collection of the Natural History Museum contains specimens from 19 species of the family Aradidae from the Palearctic region and 14 species from the Neotropical and Oriental regions. There are 16 species documented in Serbia, 14 of which are found in the collection. This paper presents three new species for Serbia: Aradus betulinus Fallén, 1807, Aradus brenskei Reuter, 1884, and Aradus somcheticus Kiritshenko, 1913. Aneurus laevis (Fabricius, 1775) was recorded on Mt. Cer after a hiatus of 100 years of being recorded in Serbia
