  Firstly we give a condition to split off the K"ahler factor from a nearly
pseudo-K"ahler manifold and apply this to get a structure result in dimension
8. Secondly we extend the construction of nearly K"ahler manifolds from twistor
spaces to negatively curved quaternionic K"ahler manifolds and
para-quaternionic K"ahler manifolds. The class of nearly pseudo-K"ahler
manifolds obtained from this construction is characterized by a holonomic
condition. The combination of these results enables us to give a classification
result in (real) dimension 10. Moreover, we show that a strict nearly
pseudo-K"ahler six-manifold is Einstein.
