“…n. has demonstrated that this triatomine has heterochromatic blocks in both extremities of practically all the autosomes and in the Y sex chromosome (Fig. 11B), unlike what has been recently stated for many populations of R. neglectus that do not present heterochromatin in autosomes (Alevi et al 2015a). Furthermore, R. taquarussuensis sp.…”

“…R. neglectus , which is a similar species for R. taquarussuensis sp. n., does not show heterochromatic blocks in the autosomes (Dujardin et al 2002; Panzera et al 2012; Alevi et al 2015a). …”

“…However, a population study was previously performed with R. neglectus (endemic species of Brazil) coming from different Brazilian states (Alevi et al 2015a) and the authors pointed out that there is no intraspecific chromosome variation for this species. This fact and the morphological data described sustain the specific status of R. taquarussuensis sp.…”

“…There was no variation in the distribution of heterochromatin blocks between P. torridus individuals displaying different color patterns. The absence of intraspecific variation was also observed for different populations of T. brasiliensis (Panzera et al, 2000), R. neglectus (Alevi et al, 2015a), and P. megistus (Alevi et al, 2015b).…”

ABSTRACT. The stink bug Pachycoris torridus is a pest of great agricultural importance due to its records on culture of physic nut (Jatropha curcas), which is the raw material for biodiesel production. An interesting feature of this insect is its high phenotypic variability, a characteristic that resulted in it being classified as a new species on eight separate occasions. In the suborder Heteroptera, the heterochromatin pattern is specific and often allows species to be differentiated. To confirm whether there is differentiation between specimens of P. torridus with different color patterns (yellow, orange, brown, and red), samples were analyzed cytogenetically using the C-banding method. During meiotic prophase, the four color patterns analyzed showed a large heterochromatic 15750 T.S. Souza-Firmino et al.©FUNPEC-RP www.funpecrp.com.br Genetics and Molecular Research 14 (4): 15749-15753 (2015) chromocenter, consisting of a combination of both sex chromosomes (X and Y). Thus, the present study reports chromosomal homogeneity in different color patterns of P. torridus and highlights the importance of this tool in the description of new species.

“…Intraspecific chromosomal variation in the Rhodniini tribe was observed in the case of R. ecuadoriensis (Pita et al, 2013) and R. pallescens (Gómez-Palacio et al, 2008). Both P. tertius and Rhodnius neglectus have been found to exhibit chromosomal homogeneity among specimens from different Brazilian states (Alevi et al, 2015b). Soares et al (2001) analyzed two P. tertius populations by using morphometry, isoenzymes, and genetic analyses; they were able to distinguish between specimens from Ceará and specimens from the Brazilian State of Minas Gerais.…”

ABSTRACT. This paper reports on the first occurrence of Psammolestes tertius in the Chapada Diamantina region, located in the city of Seabra, Bahia State, in northeastern Brazil. Following an active search, 24 P. tertius specimens were collected from Phacellodomus rufifrons (rufousfronted thornbird) nests. The insects did not present any symptoms of infection by Trypanosoma cruzi. P. tertius males were cytogenetically analyzed, and the results were compared with those of other specimens from the Brazilian State of Ceará. Triatomines from both locations presented the same cytogenetic characteristics: 22 chromosomes, little variation in the size of the autosomes, Y chromosomes that were larger than the X chromosomes, a chromocenter formed only by the sex chromosomes during prophase, and autosomes lacking constitutive heterochromatin. However, it is important to note that this species shows intraspecific chromosomal variation. In light of the results obtained, it is recommended that more studies be performed to characterize P. tertius. These studies will be particularly helpful in understanding this species in ecological, biological, biogeographical, and phylogenetic terms.
