Two species of Orchidaceae are recorded here for the first time in Mexico, namely Cryptarrhena guatemalensisand Domingoa gemma. Cryptarrhena guatemalensis is widespread in the Neotropics and can be distinguished fromC. lunata, the only other species of the genus, by possessing pseudobulbs and narrowly triangular, attenuate apicallabellum lobules. Domingoa gemma, previously known only from Guatemala and El Salvador, differs from the similarD. purpurea in the smooth, linear-lanceolate leaves and labellum lacking a prominent sac at the base. Both species areknown in Mexico from single localities in the state of Chiapas.
