Abstract
A sylvatic Triatoma infestans DM (dark morph) population detected in the Bo livian Chaco was characterized and compared with various domestic ones. The degree of differentiation of DM was clearly within the T. infestans intra- specific level. Nevertheless marked chromatic and morphometric differences as well as differences in antennal pattern, chromosome banding and randomly amplified polymorphic DNA support the hypothesis of a distinct population. Continuous exchange of insects between wild and domestic habitats seems un likely in the Chaco.
