Morphologic Study of Triatoma guazu Lent & Wygodzinsky, 1979 (Hemiptera,
Reduviidae, Triatominae) - A female of Triatoma guazu Lent & Wygodzinsky,
1979, a rare species from which the allotype was recently described, was
studied by scanning electronic microscopy and videomicroscope. Some
structures of the head and the thorax are shown. Some of them could have
taxonomic importance, as the oculo-ocellar region, the buccula, the
anterolateral angle of the collar, the scutellum, wings and the
stridulatory sulcus, which has an unusual lateral high rim.
