Microphyes (Caryophyllaceae) is a genus endemic to Chile that is recorded here for the first time for Argentina based upon the collection of M. minima in the Reserva Provincial Altoandina La Chinchilla (Dpto. Rinconada, Jujuy). The species is described and illustrated and environment notes about its habitat are supplied. A geographical distribution map is provided for the species in Argentina and Chile, and a lectotype is designated for Talinum minimum. On the other hand, the phylogenetic position of the genera within tribe Polycarpeae is confirmed. Finally, a dichotomous key to the 26 Caryophyllaceae genera recorded in Argentina is provided.
