“…The current classification of the Triatominae into five tribes and 15 genera is largely based on morphological characters, including chromatic ones (Lent and Wygodzinsky, 1979). The most commonly used characters are head and wing shape (Dujardin et al, 1999b;dos Santos et al, 2003;Dumonteil et al, 2007), but a number of other characters have been used such as the structure of the male genitalia (Obara et al, 2007), the egg (dos Santos et al, 2009), antenna (Silva et al, 2002;Catala et al, 2005) and rostrum (Silva et al, 2003). Within the triatomines, for example, the monophylly of the Rhodiniini tribe has been supported by apical antenna insertion, body forms, post-ocular callosities, male genital characteristics, egg surface architecture and salivary gland protein composition (Tartarotti et al, 2006).…”
