| Abstract | Phylogenetic approaches based on mitochondrial DNA variation (fragments of Cyt B and 16S ribosomal
RNA) have revealed Triatoma sherlocki as the most recent species addition to the Triatoma brasiliensis
species complex; a monophyletic group which includes T. brasiliensis, Triatoma melanica, and Triatoma
juazeirensis. T. sherlocki is the most differentiated among all species of this complex: it is unable to fly,
possesses longer legs than the other members, and has reddish tonality in some parts of its exochorion. We
question whether these species are reproductively compatible because of this pronounced morphological
differentiation, and therefore, we present a series of cross breeding experiments that test compatibility
between T. sherlocki and other members of the T. brasiliensis complex. We extended our analyses to include
crosses between T. sherlocki and Triatoma lenti, because the latter has been suggested as a possible member
of this complex. T. sherlocki male
×
T. lenti female pairs failed to produce hybrids. All other crosses of T.
sherlocki and members of T. brasiliensis species complex, as well as backcrosses, produced viable offspring
through the third generation. This study stresses the importance of searching for the features that may
isolate members of the T. brasiliensis species complex. | pt_BR |
