Recognition
Genus revised by Doering 1938: 501, See also Doering 1941: 215.
Neaethus can be recognized among the Gaetuliini by the forewings not strap-like, covering the abdomen; forewing transparent (some taxa with sparse markings), elongate, costal margin nearly straight; bulla absent; vertex not obtusely produced (distance from eye to the apex of the head much less than the width of the eye, head including eyes wider than pronotum; body pale; hind tibiae with 1-2 lateral spines.
Neaethus is a relatively common genus. A key to species is found in Doering (1938).

Collecting
Neaethus is collected by inspecting likely host plants or sweeping/beating.
Molecular resources
As of this writing, (surprisingly) no data for Neaethus is available on Genbank or Barcode of life.
