Possibly, some of the species may need to be transferred to other genera because of the interpretation of the morphological structure of the chelae (e.g. E. flava Lévi, 1993 and similar species with deformed chelae, which cannot be identified with certainty as palmate), others would have to be returned to Amphilectus if the style size difference would be no longer a valid discriminatory character of the two genera. Future studies using additional datasets (such as molecular sequences) are needed to clarify the status of Esperiopsis .
