It is shown that a nonlocal, suprathermal tail originated near the solar corona base dominates the. conductive energy flux at distances r ≥ 2 solar radius. A nonlocal analytical expression for the electron heat flux in weakly collisional plasmas is derived by solving the Fokker-Planck equation in a narrow, tail energy range. A correction to the anisotropy of the distribution function due to the divergent magnetic field lines was included. This term is essential to recover from the delocalization prescription, in the limit r ≥ 6 solar radius, the well-known Hollweg's Ansatz for the " collisionless " heat flux. In the intermediate region 2 solar radius ≤ r ≤ 6 solar radius, the nonlocal convolution smoothly interpolates between the classical Spitzer-Haerm's formula and the so-called collisionless regime.
