  We provide a new family of indefinite Einstein-Weyl structures of signature
(++-) on a 3-manifold, which are real analytic and space-like Zoll. They are
obtained by using the minitwistor correspondence. The minitwistor spaces we use
are Segre quartic surfaces of a particular type. They admit a $\mathbb
C^*$-action and form a 1-dimensional moduli space. Correspondingly, the present
Einstein-Weyl spaces admit a circle action and constitute a real 1-dimensional
family
