Two new species of Sobralia from Costa Rica are described and illustrated, and their affinities are discussed. Sobralia danjanzenii is compared to S. virginalis, from which it is mainly distinct by the simple stems and the unscented flowers, with the lip blotched with yellow only within the throat. Sobralia zebrina is similar to S. macrohylla, but it has much longer stems, ovate leaves that are matte on the adaxial side, and the lip is white with pale stripes alternating with brownish yellow stripes in throat.
