Re-investigation of the pigments of Hormaphis (Hamamelisters) species shows that rhodoaphin-be is a dihydroxyerythroaphin, structurally analogous to dihydroxyerythroaphin-fb but stereochemically belonging to the tt series. This follows both from spectroscopic considerations, and its epimerisation to dihydroxyerythroaphin-fb on mild treatment with acid and is consistent with its behaviour on catalytic
