    Population morphometric analysis of the tropicopolitan bug <i>Triatoma rubrofasciata</i> and relationships with Old World species of <i>Triatoma</i> : evidence of New World ancestry
    (Wiley, 2001) James Patterson; Christopher J. Schofield; Jean Dujardin; Michael A. Miles
    Quantitative analysis of morphological characters of the head was used to reconstruct the evolutionary history of the tropicopolitan bug Triatoma rubrofasciata (De Geer) (Hemiptera: Reduviidae) and seven species of Old World Triatoma. Multivariate analysis demonstrates that T. rubrofasciata and the Old World species have a high degree of similarity with Nearctic Triatoma species, particularly T. rubida (Uhler). We interpret this to imply a common ancestry for these groups. Dissemination of T. rubrofasciata and subsequent derivation of the Old World species of Triatoma is deduced to have occurred over a period of not more than 350 years.
