Description of eggs and nymphs of Triatoma klugi (Hemiptera, Reduviidae, Triatominae). The authors had described the morphologic characteristics of Triatoma klugi Carcavallo, Jurberg, Lent & Galvao, 2001 to the group of species belonging to "T. oliveirai complex". Until the moment it has been difficult to separate on the nymphs characteristics basis these species, what it justifies the development of this work. The specimens had been collected in openings of rocks in the Malavok mount in the locality of Linha Brazil, city of Nova Petropolis, in the State of Rio Grande do Sul. The local of capture of the Triatominae is placed enters 700 and 800 m of altitud (29 degrees 18'38 '' S, 51 degrees 04'57 '' W). Together with T. oliveirai (Neiva, Pinto & Lent, 1939), its morphologically related species, is the only ones of the complex that had not been found, until the moment, in the State of Mato Grosso, Mato Grosso do Sul and Goias, Brazil. In experimental conditions, already it was tested and proven its susceptibilities to the infection for Trypanosoma cruzi (Chagas, 1909) and Trypanosoma rangeli (Tejera, 1920). The comparative analysis of the ornaments of the exocorium of eggs and of three nymphs of T. klugi by optic microscopy and scanning electron microscopy showed some morphologic particularities, with prominence for: the ventral face of the head, the stridulatory sulcus and the last abdominal segments (IX, X - future genitalia and XI - anal duct). These data contribute for the magnifying of the distinguishing parameters aiming at diagnosis of T. klugi during its nymphal development.
