New provisional record for St. Eustatius. The Caribbean Anthonomus are badly in need of a modern revision. Based on the keys in Hustache (1929) and Rheinheimer (2014) and the original descriptions of Anthonomus aestuans Fabricius, 1792a, A. infirmus Gyllenhal, 1835b and A. macromalus Gyllenhal, 1835a the Eustatius specimen is provisionally assigned to the latter.
