    the difference in H.nana and H.diminuta lies in it's size and polar filaments.
    H. diminuta is bigger and has no polar filaments.
    In this case I don't see these polar filaments. (unfortunately can't operate the microscope).
    The size is conform H. diminuta.
    Is there a rodentproblem in the neighborhood ?
