The animals are 0.4 mm long. Specimens with one or two zooids were found. The colour is white in reflected light and the gut is darker with excretophores evenly distributed along both sides of the gut. The excretophores are white in reflected light and black in transmitted light. The body is slender, evenly shaped and cylindrical with both ends tapering. The anterior part of the body is long and more mobile than the rest of the body creating a head-like appearance (see fig. 3 D, prostomium in
