FIGURE 8. Bayesian inference consensus using a in Revalidation of Triatoma bahiensis Sherlock & Serafim, 1967 (Hemiptera: Reduviidae) and phylogeny of the T. brasiliensis species complex

FIGURE 8. Bayesian inference consensus using a Markov chain Monte Carlo algorithm applied to mitochondrial sequences of Cyt b fragments of 510 bp. The values over the nodes refer to bootstrap value by maximum parsimony. T. dimidiata and T. infestans were used as outgroup. Accession code of GenBank in the text.

FIGURE 7 in Revalidation of Triatoma bahiensis Sherlock & Serafim, 1967 (Hemiptera: Reduviidae) and phylogeny of the T. brasiliensis species complex

FIGURE 7. Triatoma bahiensis (2n= 22 chromosomes), male meiosis, C-banding. (A) Early first meiotic prophase: several heterochromatic chromocenters spread in the nucleus (arrowheads). A large chromocenter consists of the association of sex chromosomes plus autosomal bivalents (arrow). (B) Diplotene stage: the association between two autosomal bivalents (arrowheads) with associated sex chromosomes (arrow) is observed. (C) Diakinesis or later diplotene: ten bivalents and both sex chromosomes (XY) are clearly identified. The Y chromosome is entirely C-heterochromatic (arrow) and the X chromosome is euchromatic.

FIGURE 6. Factorial maps in the plane of the two discriminant factors of wing shape variation (canonical variables 1 and 2, or CV1 and CV2) presenting the distribution of specimens of Triatoma bahiensis (Tba, dashed polygon, open symbols) and Triatoma lenti (Tle, black polygon, closed symbols). Males are represented by squares and females are represented by circles. Drawings to the right of the plot show the consensus conformation of the wings of the species (see landmarks in Fig. 2). Arrows indicate the differences in wings of both species (see text for details).
