Paectes obrotunda is a moth of the family Euteliidae first described by Achille Guenée in 1852.

There are a few white scales forming short dashes along the costa, especially from the postmedial band to just below the apex.

There is a thin black antemedial line running from the posterior margin, forming ventral border to the faint basal spot.

This postmedial line is black and faint at the posterior margin, becoming more distinct prior to a subapical, marginal black dash.

The hindwings have a dark gray marginal band that extends to the middle of the wing with the veins highlighted in dark gray.
