Etymology.

The new species name is Latin adjective serratus, “ serrate ”, used in reference to the apically aedeagal shaft toothed like a saw.

Remarks.

This species disagrees with the subtribal diagnosis of Eremophlepsiina , as provided by Zahniser and Dietrich (2013), in having small macrosetae present laterally on the male subgenital plate, the pygofer process arising dorsally rather than ventrally, and the valve distinctly shorter than wide.
