Three new species of the flat bug family Aradidae from the Eocene Messel Maar are described and illustrated. Aneurus ? incertus n. sp. is a new species belonging to the extant subfamily Aneurinae. Mezira petrificata n. sp. and M. parapetrificata n. sp. are two new species belonging to the extant subfamily Mezirinae. They are compared with the specimens so far described from Messel, as well as with related extant taxa. Additionally, a male probably belonging to M. eocenica and a female of M. petrificata are reported. Even though the aradids represent less than 0.05 % in the taphocoenosis from Messel, and are one of the smallest groups among the recorded heteropterans, the presence of six species among eight preserved specimens indicates an unexpected high diversity among flat bugs from Messel. Especially well-represented are members of the subfamily Mezirinae that today occur in all major biogeographic regions but seem to be concentrated in the Southern Hemisphere.
