Alsobia baroniae L. E. Skog & Barrie, a new species of Alsobia Hanst. (Gesneriaceae: Episcieae), is described from the karst region of central Belize. The new species is endemic to Belize, known from but a few collections, and is distinguished from the other three known species of Alsobia mainly by its larger leaves, 10–26 cm long, and its densely pilose corolla. The genus is now expanded to four species. A synopsis of the genus is given, including descriptions of the genus and known species and a key to species.
