Resumo
In nests of opossum (Didelphis aurita), localized in palm-trees of the species Attalea indaya Dr., the authors found a new tritatoma, the description of which is being made by Dr. H. LENT. They verified that this triatoma had been naturally infected by Trypanosoma (Schizotrhypanum) cruzy. Two guinea-pigs were subsequently infected by peritoneal inoculation of excrements of this new triatoma. The xenodiagnosis of these guinea-pigs, made with normal nymphas of. T. megistus and T. infestans resulted positive after 25 days. Evidence was obtained of being the opossum (Didelphis) one of the sources infection of the new vector, because several specimens of them were found infected, and also a specimen of D. aurita, which contained trypanosomes with the morphology of T. (S.) cruzy in the peripheral blood.
