population morphometric analysis of the tropicopolitan bug triatoma rubrofasciata and relationships with old world species of triatoma: evidence of new world ancestry. | 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. ru ... | 2001 | 11776464 |
