There is virtually no information on this species in the literature besides the original description. Preliminary surveys by Division of Plant Industry inspectors and data enclosed with the original series of specimens suggest this weevil has an extremely broad host range. However, it differs in many details, the most conspicuous of which is the dark mottling of the upper surface and the yellowish head. All the femora are spined in M. undatus , as opposed to A. floridanus , in which none of the femora are spined. Compare figures of the two species below.
Surveys are ongoing to delimit the extent of the infestation.
