  We study the properties of the level statistics of 1D disordered systems with
long-range spatial correlations. We find a threshold value in the degree of
correlations below which in the limit of large system size the level statistics
follows a Poisson distribution (as expected for 1D uncorrelated disordered
systems), and above which the level statistics is described by a new class of
distribution functions. At the threshold, we find that with increasing system
size the standard deviation of the function describing the level statistics
converges to the standard deviation of the Poissonian distribution as a power
law. Above the threshold we find that the level statistics is characterized by
different functional forms for different degrees of correlations.
