The Ap star HD 83368 may be a lithium-spotted pulsator.

NORTH P., POLOSUKHINA N., MALANUSHENKO V. and HACK M.

Abstract (from CDS):

Several observations of some Ap stars have been made at the ESO, Nordic and Crimean telescopes in 1996. Interesting results have been found for the roAp star HD 83368 = HR 3831 in the Li spectral region. These have shown the presence of two almost diametrically opposed spots of Li or of the element responsible for the ``Li'' blend, which cause strong variations in the profile and position of the Li blend at 6708Å.
