We report results of a search for narrow resonances in e + e − annihilation at center-of-mass energies between 1.85 and 3.1 GeV performed with the KEDR detector at the VEPP-4M e + e − collider. The upper limit on the leptonic width of a narrow resonance Γ R ee · Br(R → hadr) < 120 eV has been obtained (at 90% C.L.).
