A new species of the aberrant monotypic genus Planotergum Balss, 1935 (Brachyura: Majidae: Planoterginae) is described from the southern part of the Red Sea, based on a single female recently found in the collection of the Zoological Museum of Moscow State University. The new species is clearly distinguished from Planotergum mirabile Balss, 1935 in the form of carapace, antennal article and third maxilliped, as well as morphology of the ambulatory legs. The record extends the known range of Planotergum, previously known only from the eastern Indian Ocean and Western Pacific, by more than 7000 km.

Key words: Decapoda, Planoterginae, Planotergum, new species, Red Sea.
