Two new records, Pusillanthus pubescens (Rizzini) Caires for the state of Pernambuco, and Struthanthus meridionalis Kuijt for the state of Mato Grosso, are presented, as well as records of new host families: Fabaceae, Malvaceae, Rutaceae and Solanaceae. Struthanthus polyanthus var. gracilis is proposed as a taxonomic synonym of S. meridionalis. An isotype of Struthanthus pubescens, located in the Field Museum herbarium, is chosen as its lectotype.
