The phylogenetic analysis of the subtribe Gonolobinae allowed to determine the position of Matelea balansae Morillo & Fontella, a taxon that was not related to the clade of the genus Matelea Aubl. sensu stricto, nor was grouped into other generic clades. This leads to the foundation of a new monotypic genus, Caa H. A. Keller & Liede. Morphological information, complementary to the original diagnosis of the species, is included.
