Exotic in Leptonic Machines

Selected topics of exotics in leptonic machines are presented, including recent discovery of abnormal structures around the pp-bar threshold and new information of the XYZ (charmonium-like) states. The main body of the paper is divided into two parts, one is for the light-hadronic spectrum and the other one is for heavier charmonium-likes states. The first part contains the recently found structures near pp-bar threshold such as X(pp-bar), X(1835), X(1840), X(1870), X(1810). The second part contains the very recent advances on the XYZ (charmonium-like) states, such as new production mode, the discoveries of new resonances, and updating previous measurements with larger statistics
