 While the authors of the 2008 analysis made no explicit comment on the status of the newly proposed genus, they thus found the "S. gambarelloides" species group to be well-marked, and their results certainly harden the case for recognition of "Zuzalpheus" at least as a subgenus.However, this analysis only included 2 species from the "S. gambarelloides" species group, and none from the Caribbean, where the vast majority of the group resides.Opinion is still divided, however, and recently "Zuzalpheus" was synonymised with "Synalpheus".
