We present the results of a search for Higgs bosons predicted
in two-Higgs-doublet models, in the case where the Higgs bosons decay to
tau lepton pairs, using 1.8 fb-1 of integrated luminosity of p anti-p
collisions recorded by the CDF II experiment at the Fermilab Tevatron.
Studying the invariant mass distribution in events where one or both
tau leptons decay leptonically, no evidence for a Higgs boson signal
is observed. The result is used to infer exclusion limits in the
two-dimensional parameter space of tanB versus m_A.
