Cell c is a small rectangular cell on the anterior margin of the wing between the costa and vein Sc. It is bordered basally by crossvein h. It is within the C-band, but its color is often paler than most of the rest of the band. It often has diffusely paler areas within it, especially posteriorly, but in some species it is infuscated basally and has a distinctly delimited subapical hyaline area. Specimens that are diffusely paler subapically or subbasally and subapically should be scored state 1.
