The production of inclusive, prompt and non-prompt J/psi was studied for the first time at midrapidity (-1.37 < y(cms) < 0.43) in p-Pb collisions at root sNN = 8.16 TeV with the ALICE detector at the LHC. The inclusive J/psi mesons were reconstructed in the dielectron decay channel in the transverse momentum (p(T)) interval 0 < p(T) < 14 GeV/ c and the prompt and non-prompt contributions were separated on a statistical basis for pT > 2 GeV/c. The study of the J/psi mesons in the dielectron channel used for the first time in ALICE online single-electron triggers from the Transition Radiation Detector, providing a data sample corresponding to an integrated luminosity of 689 +/- 13 mu b(-1). The proton-proton reference cross section for inclusive J/psi was obtained based on interpolations of measured data at different centre-of-mass energies and a universal function describing the p(T)-differential J/psi production cross sections. The p(T)-differential nuclear modification factors R-pPb of inclusive, prompt, and non-prompt J/psi are consistent with unity and described by theoretical models implementing only nuclear shadowing.
