However, the pharyngeal glands could not be seen in our specimens, which also showed epidermal inclusions (fig. 7G: ei). These inclusions are similar to the rosette-shaped glands described in  Stenostomum glandulosum Kepner & Carter, 1931, which also has a prostomium-like anterior end.  Stenostomum anatirostrumMarcus, 1945also shows a prostomium-like anterior end but is much larger in size.
