  A novel contribution to the leptonic CP asymmetries in type II seesaw
leptogenesis scenarios is obtained for the cases in which flavor effects are
relevant for the dynamics of leptogenesis. In the so-called flavoured
leptogenesis regime, the interference between the tree-level amplitude of the
scalar triplet decaying into two leptons and the one-loop wave-function
correction with leptons in the loop, leads to a new nonvanishing CP asymmetry
contribution. The latter conserves total lepton number but violates lepton
flavour. Cases in which this novel contribution may be dominant in the
generation of the baryon asymmetry are briefly discussed.
