Eurystyles comprises about 23 species ranging from Mexico to northern Argentina. Six species are recog-nized in Mexico and Central America and three in Costa Rica. A new species, named E. uxoris, is here described and illustrated based on Costa Rican material. The species is similar to Eurystyles auriculata and E. standleyi, however, it differs by the smaller plants up to 3 cm tall, smaller leaves of less than 1.6 cm long, flowers with brown dorsal sepal and brown lip apex, petals callose or thickened at apex, and a pandurate lip. Information about dis-tribution, habitat, ecology, etymology and phenology of the new species is provided. An updated key to the Costa Rican species of Eurystyles is presented.
