Andesanthus is a genus of flowering plant in the family Melastomataceae, native to Colombia, Costa Rica, Ecuador, Panama, Peru and Venezuela.[2]
Taxonomy
The genus Andesanthus was erected in 2019.[1] In 1885, in his treatment for Flora brasiliensis, Alfred Cogniaux used a broad concept of the genus Tibouchina, transferring into it species at that time placed in many other genera. This broad concept was generally adopted subsequently, and around 470 taxa were at one time or another assigned to Tibouchina, including those placed in Andesanthus in 2019.[3] A phylogenetic analysis in 2013 based on molecular data (2 plastid and 1 nuclear regions) showed that the traditional circumscription of Tibouchina was paraphyletic. Four major clades were resolved within the genus, which were supported by morphological, molecular and geographic evidence.[4] A further molecular phylogenetic study in 2019 used the same molecular markers but included more species. It reached the same conclusion: the original broadly circumscribed Tibouchina consisted of four monophyletic clades. The authors proposed a split into four genera: a more narrowly circumscribed Tibouchina, two re-established genera Pleroma and Chaetogastra, and a new genus, Andesanthus. The part of their maximum likelihood cladogram which includes former Tibouchina species is as follows,[3] using their genus names and with shading added to show the original broadly circumscribed Tibouchina s.l. (The relationship between Chaetogastra and the genus Brachyotum differed between analyses.)

Andesanthus is shown to be sister to either Chaetogastra or a clade combining Chaetogastra and Brachyotum.[3]
