We study the Riemann curvature tensor of (\kappa,\mu,\nu)-contact metricmanifolds, which we prove to be completely determined in dimension 3, and weobserve how it is affected by D_a-homothetic deformations. This prompts thedefinition and study of generalized (\kappa,\mu,\nu)-space forms and of thenecessary and sufficient conditions for them to be conformally flat.
