Willdenowia 37: 323-329.

Restrepiella lueri is described as a species new to science and illustrated from Costa Rica. The new species differs from R. ophiocephala by (1) the free lateral sepals with irregularly dentate margins, (2) the glabrous petals provided with three low, longitudinal keels, (3) the elliptic, simple lip, longer than the column and as long as the petals, ciliate along the margins and hirsute at apex, with three longitudinal keels from the base extending to the middle of the blade, and (4) the column without a foot. A key to the species of Restrepiella is provided.
