In this talk we address two topics: The first one is an empirical explanation in terms of a new state h(1) of the peak in the K*(0)(K) over bar*(0) invariant mass distribution close to threshold of this channel in the J/psi -> eta K*(0)(K) over bar*(0) decay. The second one is a theoretical description of the isospin I = 1 Z(c)(3900) and Z(c)(4020) states in terms of molecular states of D (D) over bar* + cc and D*(D) over bar*.
