All three limbs with a fancy subdivision of their protopo d, differing anteriorly and posteriorly. Trunk composed of 11 annular segments, which reveal little differentiation of the trunk into a thorax and an abdomen. First trunk segment with a tergite with weakly defined lateral margins, next segment annular but with a concavity in its anterior ventral side covered by soft cuticle to permit posterior flexure of the maxillipeds. All trunk segments with well developed joint membrane dorsally and slightly posteriorly extended at their ventrocaudal margins, limiting ventral flexure of the tail . The telson is long and conical, carrying the anus dorsoterminally and articulated furcal rami.
More differences are also in the forehead region and the shape of the shield .
Possibly these two species were vertically stratified in their occurrence in the flocculent bottom zone, since they co-occur in the samples.
