Many Parastephanellus specimens can be still recognized by Enderlein's original diagnosis, but some species can eventually be confounded with Hemistephanus. Nevertheless, the geographic distribution of the two groups are distinct enough to prevent such mistake of ocurring with labelled specimens. However, whether Hemistephanus is trully related to Parastephanellus or not has never been proved, and the monophyly of the genus Parastephanellus itself was never assessed.
