Takapsestis semiobsoleta is a moth in the family Drepanidae.

The forewings are pearl grey, the subbasal line angled outwards below the costa and forming an oblique black dash near the base of the submedian fold, with a reddish tinge around and below it.

The outermost line is blackest, oblique and excurved below the middle, then indented.

Close before the termen is a row of black dashes between the veins.

The hindwings are pale dull grey, with a broad fuscous terminal border and indistinct dark outer band.
