          Abstract

          Sete espécies da região neártica: Triatoma barberi Usinger, 1939; T. rubida (Uhler, 1894); T. gertaeckeri (Stal, 1859); T. lecticularia (Stal, 1859); T. protracta (Uhler, 1894); T. recurva (Stal, 1868) e T. sanguisuga (Leconte, 1855) foram analisadas comparativamente, tendo como enfoque as estruturas da genitália do macho: falosoma (Ph), suporte do falosoma (SPh), processo do endosoma (PrEn), vesica (V) e aparelho articular (Apb). As estruturas fálicas se mostraram capazes de serem usadas como critério morfológico suplementar aos padrões atualmente usados, em taxonomia. Estas espécies silvestres são encontradas nos Estados Unidos e México, naturalmente infectadas pelo T. cruzi; algumas vivem no perdomicílio e outras eventualmente no domicílio, sem contudo colonizá-lo.

          Translated abstract

          Seven species from the neartic region, Triatoma barberi Usinger, 1939; T. rubida (Uhler, 1894); T. gerstaeckeri (Stal, 1859); T. lecticularia (Stal, 1859); T. protracta (Uhler, 1894); T. recurva (Stal, 1868) and T. sanguisuga (Leconte, 1855) were comparatively analysed with emphasis on the genital structures of the male bug: the phallosome (Ph), the phallosome struts (SPh), the endosoma process (PrEn), the vesica (V) and the articulatory apparatus (Apb). The phallic structures were useful as a supplementary morphological criterion to the present taxonomical standards. These wild species are found naturally infected by Trypanosoma cruzi in the United States and Mexico. Some of them live outside human dwellings while other are occasionally domiciliary, although they do not colonize these homes.
