Summary

A new species, Mesosphaerum caatingense Harley & J.F.B.Pastore (Lamiaceae: tribe Ocimeae: subtribe Hyptidinae), is described from the semi-arid Northeast region of Brazil known as the Caatinga biome, included under the domain of the STDF (Seasonally Tropical Dry Forest). The generic placement and its conservation status are assessed and its phenology is discussed. The new species is compared with some of its morphologically allied species, M. pectinatum, M. irwinii and M. sidifolium. Illustrations, photographs, a distribution map and a key to Brazilian species are also provided.
