Eurystyles comprises about 23 species ranging from Mexico to northern Argentina. Six species are recognized 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 distribution, habitat, ecology, etymology and phenology of the newspecies is provided. An updated key to the Costa Rican species of Eurystyles is presented.
