In an anisotropic plasma, the electrostatic shielding of a static test particle is always complete for an arbitrary distribution function. In this paper the analytical formula and the numerical values of the electrostatic shielding potential in a bi-Max-wellian plasma are given. When the distance R is large, the potential is proportional to R-3. Under certain conditions, there might appear some supershielding regions about the test particle.
