Lethata trochalosticta is a moth in the family Depressariidae.

The forewings are olivaceous dark yellowish green, with a slight steely sheen beyond the cell.

A reddish brown shade from the middle of the base blends outward and downward with the olivaceous ground colour, changing above to rosy red along the costa to two-thirds.

A conspicuous, round, rosy red spot lies at the end of the cell, with a dark fuscous spot in its centre, and a narrow even rim of reddish brown.

The hindwings are ochreous, with a slight fuscous suffusion.
