Critical morphological study of the type of Leiomitra robusta (Steph.) R.M.Schust. (≡ Trichocolea robusta Steph.) showed that L. robusta is conspecific with L. paraphyllina Spruce. The former species is proposed as a synonym of the latter. Mexican plants previously reported as T. robusta were also examined and appeared to belong to L. paraphyllina as well, confirming results of previous authors. The latter species is widely distributed in Central and South America. A worldwide key to the species of Leiomitra is provided.
