Diagnosis : Female. Pereomeres without mid-dorsal projections. Pleomeres 1–5 with strongly elongated lateral plates lacking digitation on margins; five pairs of biramous pleopods, endopods much smaller than exopods; uropods well developed, uniramous. Male : Pereomeres and pleomeres distinctly segmented. Pleon lacking midventral tubercles, pleopods as low rounded swellings on pleomeres 1–5; pleotelson with large distolateral lobes, lacking true uropods. Remarks : Females of species in Epicepon can be distinguished from those of other keponine genera in having oostegite 1 not protruding forward, no mid-dorsal processes on any pereomeres, lacking well-developed digitation on the margins of the lateral plates or pleopods, and small pleopodal endopods and large exopods (Nierstrasz and Brender à Brandis 1931). Nierstrasz and Brender à Brandis (1931) did not designate a type species for Epicepon ; we select E . japonicum as the type species herein.
