Abstract
During the taxonomic revision of the genus Stigmatodon, we found an unknown epilithic mat-forming species, morphologically close to S. belloi, on vertical granitic surfaces on inselbergs in southern Espírito Santo state, Brazil. We described and illustrated the new species, including a comparative analysis of characters that distinguish it from similar species. We also provide data on habitat, ecology, geographical distribution and evaluation about its threat of extinction according to the criteria of the IUCN.

Stigmatodon attenuatoides D. R. Couto, Manhães & A. F. Costa, sp. nov.
Etymology:—The epithet of this new species alludes to the resemblance between its leaves and those of Agave attenuata Salm-Dyck (1834: 303, Asparagaceae), which are green and covered by a thick layer of white epicuticular wax too.
