Morphometric analysis of Old World species of Linshcosteus and Triatoma showed the two genera to be well separated. However, although the analysis showed clear distinction between the five species of Linshcosteus. There was considerabnle overlap between the eight Old World species of Triatoma, including specimens of T. rubrofasciata from Old and New World populations. The results are interpreted as supporting the idea of a New World origin for the Old Word species of Triatoma, with an independent Old World origin of Linshcosteus.
