Suphisellus epleri Arce-Pérez and Baca, 2017

( Fig. 19 )

This species is recorded from the Neotropical region in Mexico (Arce-Pérez and Baca 2017). Suphisellus epleri is similar to S. neglectus , differing by the presence of the median lobe in lateral view less dilated towards the apex (always expanded in S. neglectus ).
