“…We show that APA 7 alone is sufficient and does not require backup by APA 8 or other characters. In the reduviid Triatoma pallidipennis , the 9th sternite of nymphs was shown to be divided in females but not males (Rodríguez‐Sánchez, Alejandre‐Aguilar, Nogueda‐Torres, Camacho, & Martín‐Frías, 2003) and we confirm this observation in C. lectularius .…”

“…Morphological and morphometric analyses conducted with other structures, such as the scutellum, genital plates in nymphs, and egg ornamentation, have shown no polymorphism in several Meccus species. At the same time, these studies have provided discriminant characters to differentiate among species (Rodríguez‐Sánchez et al , Takashi et al , Rivas et al , ).…”

Triatomine classification is based on morphological characteristics. Studies have been conducted to improve their identification by observing many characteristics. However, there are problems of differentiating among highly interrelated species and new criteria are required. The purpose of this study was to determine the morphological differences in the external female genitalia of M. pallidipennis, M. longipennis, M. picturatus, M. bassolsae, M. mazzottii, and M. phyllosomus in order to distinguish among species using scanning electron microscopy. Observations were made of the dorsal, posterior, lateral, and ventral views of the female external genitalia for each species. In the six species we studied, relevant differences were observed in the dorsal view of the X segment, as well as the IX, VIII, and VII tergites. In the posterior and lateral view, the most visible differences were registered in the gonocoxite size of the segments VIII, IX, and X. Finally, in the ventral view of the VII sternite, differences among species were observed in the size of the inflection in the top and upper corner. Our results show that it was possible to differentiate among the triatominae species for each of the four views by using a scanning electron microscope to analyze morphological characteristics of the VII, VIII, IX, and X abdomen segments.

“…The sex of the specimens was later confirmed at the adult stage. The treatment used for the analysis of the genital plates was described by Rodriguez‐Sanchez et al (2003). Photographs of the genital plates were taken with a stereoscopic microscope.…”

“…The study of the development of genital plates in nymphs has been useful for sex differentiation and has taxonomic value (Lent and Wygodzinsky 1979, Rodríguez‐Sánchez et al 2003, Rosa et al 2010). The first studies were conducted by Galliard (1935), later, the contributions of Corrêa (1954), Corrêa et al (1964), Espínola (1966), Ramírez‐Pérez (1969), Salgado et al (1979) and others have been important in the study of this structure in species of Triatominae as T. infestans , T. brasiliensis , T. dimidiata , Rhodnius prolixus and others species of epidemiological importance.…”

The control of triatomine insects is necessary because these insects are the principal vectors of Trypanosoma cruzi, the agent of Chagas disease. Nevertheless, some of these vectors, such as Triatoma protracta, have not been studied adequately and their importance and taxonomic status has not yet been defined in detail and must be reevaluated in view of the continuing taxonomic uncertainties associated with the species. To help clarify the taxonomic status of T. protracta, the eggs and genital plates of two morphotypes were analyzed. Qualitative and quantitative morphological differences were observed in two morphotypes, designated T. p. protracta and T. p. nahuatlae according to Ryckman (1962). The morphotype T. p. protracta exhibited large and wide eggs with pores forming large padded polygonal structures, whereas the eggs of the morphotype T. p. nahuatlae were small and smooth. The size of the 9 th genital urosternite was longer and wider in females in contrast to males in both morphotypes. However, these size differences were relatively greater in T. p. protracta. The high morphological variation found between the morphotypes of T. protracta suggests that they should be separated. Accordingly, it is probable that this group should be re-classified.
