Nova espécie do complexo oliveirai (nova denominação para o complexo matogrossensis) (Hemiptera, Reduviidae, Triatominae) do estado do Rio Grande do Sul, Brasil

Evolutionary Relationships of the Triatoma matogrossensis Subcomplex, the Endemic Triatoma in Central-Western Brazil, Based on Mitochondrial DNA Sequences

“…The other two recovered clades of Triatoma from Central-Western Brazil actually corroborated morphometric and isoenzymatic phylogenetic analyses by Noireau and others 16 focusing on the called “ T. oliveirai complex” (actually T. matogrossensis subcomplex, according to Carcavallo and others 54 and Schofield and Galvão 13). Both distance analyses of morphological measurements and 20 isoenzyme loci support a close relationship between T. vandae and T. jurbergi as a sister clade of T. matogrossensis , whereas T. guazu and T. williami with a significant distance from T. klugi .…”

Biology of Triatoma klugi Carcavallo, Jurberg, Lent & Galvão 2001 (Heteroptera: Reduviidae) under Laboratory Conditions: Effects of Distinct Blood Sources and Susceptibility to Trypanosoma cruzi and Trypanosoma rangeli

“…Triatomines used in this study were the F1 generation obtained from adults and nymphs collected at Nova Petrópolis, State of Rio Grande do Sul, Brazil (Carcavallo et al 2001). The original colony was established in our laboratory in 1999 and is maintained under 28 ± 1ºC of temperature and 75 ± 5% of relative humidity (r.h.) and fed weekly on Swiss mice.…”

“…klugi is a new triatomine species originally found in rock cracks without or with scarce vegetation in the State of Rio Grande do Sul, Southern Brazil (Carcavallo et al 2001). Morphologically related to T. oliveirai this new species was included into the "oliveirai complex", which also comprises T. matogrossensis Leite & Barbosa 1953, T. oliveirai (Neiva, Pinto & Lent) 1939, T. williami Galvão, Souza & Lima 1965, T. guazu Lent & Wygodzinsky 1979and T. jurbergi Carcavallo, Galvão & Lent 1998(Carcavallo et al 2001. Preliminary data about T. klugi blood sources derived from precipitin tests revealed the presence of bird and rodent blood, as well as coackroaches hemolymph (Carvalho-Pinto et al 2000).…”

A study of the scutellum in eight Chagas disease vector species from genus Triatoma (Hemiptera, Reduviidae) using optical and scanning electron microscopy

“…2D). According to Carcavallo et al (2001) the scutellum of T. klugi has the central depression deep and the posterior process conical and short. T. vandae has a sub-conical posterior process, narrow at the base, in addition to perceptible transverse sculptures along the entire process, including the apex (Fig.…”
