A yellow-flowered Chiloschista (Orchidaceae, Aeridinae) with brown-spotted tepals is described as a new species. It was
initially collected in Son La Province, Thuan Chau District, and later flowered in cultivation when it was identified as a new
specie. This new species resembles C. parishii and C. himalaica in habit, shape and color of the flower, but differs from C. parishii and C. himalaica by glabrous sepals and lip ornamentation characters. The paper includes the standard description, the plate with analytical photos, data on habitat, phenology, and conservation status of the new species.
