In the present paper we revise within the same framework the semi-classical black hole bound on the number of particle species N_{species}. We show that unlike the bound on global charge, the bound on species survives in the quantum picture and gives rise to a new fundamental length-scale, L_{species} = sqrt{N_{species}} L_P$, beyond which the resolution of species identities is impossible.
