The reactions e+ e- --> hZ* and e+ e- --> hA have been used to search for the neutral Higgs bosons h and A of the MSSM in the case where the CP-odd A is lighter than 2m(mu), taking into account the large h --> AA decay branching ratio. No signal was found in the data sample collected until the end of 1991 by the ALEPH experiment at LEP. For tan beta greater-than-or-equal-to 1, m(A) < 2m(mu) is excluded at 95% CL for any m(h).
