Résumé
Because of its incomplete original description, the monotypic genus Wernhamia has long been considered a dubious taxon. Recent Bolivian collections by the junior author and other collections from Peru have revealed the identity of Wernhamia boliviensis; it is synonymous with Simira macrocrater, and Wernhamia is therefore congeneric with Simira. A complete description, illustration, and distribution map of this species are provided.
