Poore, G. C. B., 1994.Maricoccus brucei, an unusual new genus and species of Sphaero- matidae from southern Australia (Crustacea: lsopoda).Memoirs of the Museum of Victoria 54: 171-178.A new monotypic genus is diagnosed, the first among Sphaeromatidae with complete fusion of pleonite I to the remaining pleonites.It belongs to a group of dynamenine genera in which the first pleopods are operculiform, the first pleonal sternite is long, and the mandibu- lar incisor is unicuspidate.The new genus is exceptionally flattened, more than in species of Juletta Bruce, 1993 and Margueritta Bruce, 1993 which it resembles.It differs from these two in the possession of falcate percopodal dactyli.
