Brontostoma doughertyae n. sp. (Hemiptera-Heteroptera: Reduviidae: Ectrichodiinae), from Espírito Santo and Bahia States, Brazil is described based on male specimens. A comparative analysis between the phallic structures of Brontostoma rubrum (Amyot & Serville, 1843) and B. doughertyae sp. nov. is presented. Three structures are important to distinguish them: the gonoporal process (PrG); support of the phallosoma (SPh) and the phallosoma (Ph). A key for the brazilian species of Brontostoma is presented.
