Melanodrymia ?galeronae is most likely to be confused with its congener, Melanodrymia aurantiaca. The protoconchs are very similar in size and general appearance. However, the sculpture is finer on M. ?galeronae, the aperture is less strongly sinuous and it lacks the distinct bump above the aperture.
Neomphalid sp. B - This protoconch is very similar in size and general appearance. However, it has a thin ridge that parallels the aperture, forming a distinct rim. The aperture is straighter in this species and the sculpture is stronger and more regular, forming distinct rows at the anterior end of the shell.
Unknown neomphalid 290µm - This protoconch is very similar in general appearance and sculpture and may well be an undescribed Melanodrymia species. It is, however, larger (290µ against 250µm) and the aperture is more deeply sinuous, as well as flaring out more at the outer edge.
Bathymargarites symplector - This protoconch is similar in general appearance, but is much larger (~350µm) and lacks the overall reticulate sculpture.
