Chlamydastis complexa is a moth of the Depressariidae family. It is found in French Guiana. The wingspan is 24–26 mm. The forewings are white, faintly greenish-tinged, irregularly irrorated with grey and dark fuscous and with a cloudy dark grey line from one-fourth of the costa to two-fifths of the dorsum, obtusely angulated below the middle. There is a transverse-linear dark fuscous mark on the end of the cell and a small dark fuscous spot on the middle of the costa, where a series of small indistinct dark fuscous marks runs obliquely outwards to beyond the cell, then angulated to three-fourths of the dorsum, and a curved dark fuscous line from a spot on the costa at three-fourths to the dorsum before the tornus, the dorsal space between these forming a dark grey blackish-edged blotch rea
