Systematic features of anomalous signature splitting of the pih(11/2) circle times nui(11/2) band in A similar to 160 odd-odd nuclei have been investigated. It is shown that the mechanism of anomalous signature splitting is similar to that of the normal signature splitting which is essentially caused by the Coriolis mixing of Omega = 1/2 components into the nuclear wavefunction and the anomalous splitting in signature is mainly caused by the definition. The extensively observed anomalous signature splitting in this band might be an indication that the interaction between the h(11/2) proton and the i(13/2) neutron cannot be neglected. The new observation of high- and low-K bands based on the same pih(11/2) circle times nui(13/2) configuration in Tm-164 is also discussed.
