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.
