Abstract

A new species of the genus Coulteria from the seasonally dry forest of the Rio Balsas Depression, Mexico is described and illustrated. Coulteria sousae is morphologically most similar to Coulteria pringlei but differs from it by having smaller flowers (1 cm long), long stipitate fruit, leaflets that are glabrous and coriaceous at maturity, and an allopatric distribution. The conservation status of this species is suggested to be Endangered (EN), according to the IUCN Red List Categories and Criteria.
