  We examine the symmetries of the action suppelemented by the constraint in
the WZW-type open superstring field theory. It is found that this pseudo-action
has additional symmetries provided we impose the constraint after the
transformation. Respecting these additional symmetries, we propose a
prescription for the new Feynman rules for the Ramond sector. It is shown that
the new rules reproduce the well-known on-shell four- and five-point amplitudes
with external fermions.
