Abstract

Stachytarpheta tomentosa from the state of Espírito Santo, Brazil, is described and illustrated. Currently it is known only from a single inselberg in the Atlantic Forest, at approximately 900 m.a.s.l., and is considered Critically Endangered in accordance with the criteria of the IUCN Red List of endangered species. The new species is characterized by tomentose branches; lanceolate leaves with tomentose abaxial surface; tomentose bracts; calyx 4-toothed with 1 adaxial sinus, externally hirsute along the ribs, puberulent between the ribs; and blue corolla with white throat. It belongs to the informal group “Gesnerioides”. An identification key for the species of this group is provided, alongside description, map and illustrations.
