Abstract Systematic knowledge of the Mexican Crassulaceae is slowly progressing as data from new DNA regions and species sampling efforts increase. We compiled and generated new rbcL , matK , rps16 , ITS/ITS2, and ETS DNA sequences and performed an updated phylogenetic reconstruction for a group of 131 Mexican Crassulaceae terminals from 11 of the 13 recognized genera present in Mexico. Topological incongruences were found between the consensus trees of plastid and nuclear partitions. The maximum likelihood consensus tree for combined genomic regions supports only one historically recognized genus and some of the most recent grouping proposals, such as the recognition of Urbinia , and a new genus proposed here. The five‐region matrix and expanded species sampling have improved the resolution and bootstrap support for these groups compared to previous studies. The new genus Balbinaea , formally described here, was recovered only in a combined analysis as the sister group of Echeveria ser. Gibbiflorae. Balbinaea is the result of the merger of E. ser. Angulatae , ser. Pruinosae , and ser. Secundae .
