Exotics at BESIII

With a collected integrated luminosity of about 12 fb−1, useful data set for XYZ new resonances, BESIII continues the exploration of these exotic charmonium-like states. In this proceeding, recent results on the measurements of the line-shape of e+e− → π+π−ψ(3868) and π+D0D*−, as well as the JP determination of ZC (3900) will be presented. An abundance of Y will be reported in several decay channels. Finally the present BESIII data above the ${e^ + }{e^ - }\, \to \,{\Lambda _C}{\bar \Lambda _C}$ threshold will be shortly discussed because they are barely in agreement with the current Belle data on the candidate charmed baryonium state Y(4660). A BEPCII upgrade, that will allow to settle this open question, has been funded
