Euphilomedes tasmanicus n. sp. is described in this paper. The species was collected from the estuary of the Huon River in Tasmania, Australia. It is most closely related to another Australian species, E. ernyx Kornicker, 1995. They share three rare characters: more than three bristles on the basale of the mandible, more than one bristle on the coxale of the maxilla, and only one bare peg opposite the comb on the seventh leg. They differ in the actual number of bristles on the basale of the mandible, number of furcal claws and the morphology of their carapaces. Both species belong to a group of species of Euphilomedes Kornicker, 1967 having only the third furcal claw secondary (inserted between two primary claws). Euphilomedes africanus (Klie, 1940) is also redescribed here based on the type material from the Zoological Museum in Hamburg. This species is characterized by a long second segment on the endopod of the first antenna of the female, and also, by having no pegs opposite the comb on the seventh leg. The species belongs to a second group of Euphilomedes having furcal claws three and four secondary. Including the new species, the genus has 25 valid species. A key to species, as well as a map of their distribution is presented.
