We report results of a search for narrow resonances in e super(+e) super(-) annihilation at center-of-mass energies between 1.85 and 3.1 GeV performed with the KEDR detector at the VEPP-4M e super(+e) super(-) collider. The upper limit on the leptonic width of a narrow resonance [inline image] has been obtained (at 90% C.L.).
