摘要：

Two new species of Matelea from central Mexico with nearly black corollas and papillate lobes are described here: Matelea tezcatlipocantha and Matelea tlilxochitli. These taxa differ from each other and from morphologically similar species (e.g. M. calcicola, M. chrysantha, M. congesta, and M. inops) by the corolla tube and corona ornamentation. Descriptions, illustrations, morphological comparisons, and geographic distributions of these species as well as their conservation status are provided. This discovery highlights Mexico as a center of diversity and endemism for the genus, as more than 70 species are currently found there, with 60% of those species being restricted to the country.
