> Serratella

Prior to recent revisions, this genus of elegant little dark mayflies with their small dark bodies, dark slate wings, and paler legs and tails was more important to anglers. What was the East's most significant species is now known as Teloganopsis deficiens (Little Black Quill). The only remaining species reported of value to the eastern angler is Serratella serrata (Little Sooty Olive).

These changes have had an even bigger impact in the West. The significant Summer hatching tibialis has been moved back to its old genus and is again called Ephemerella tibialis (Small Western Dark Hendrickson). The next most prominent species (though of only minor importance) is now called Matriella teresa and is the only recognized species of that genus in North America. The very minor species velmae has also been moved, and is now back in Ephemerella. This leaves only a few western species in this genus, and they are of no reported significance to anglers.
