Fine structure in the α decay of high-spin states in Lu156 and Ta158 has been identified by means of αγ-coincidence analysis. One new α decay from Lu156 and two from Ta158 were identified, one of which was found to populate a previously unknown state in Lu154. The hindrance-factor systematics from all four odd-odd, N=85 nuclei with known α-decaying, πh11/2 coupled states were reviewed and are discussed. These proved consistent with the previously assigned (πh11/2νh9/2)10+ configuration of the α-decaying state in Lu156, which differs from the (πh11/2νf7/2)9+ assignments in the other three nuclei.
