Karyotype evolution of the South American subcomplexes. (1) Subcomplexes that remained with the same number of chromosomes from the ancestral karyotype (T. brasiliensis, T. infestans, T. matogrossensis, T. maculata, T. rubrovaria and T. sordida). (2) T. vitticeps subcomplex. Note that the species in this subcomplex have undergone two agmatoploidy events in the X chromosome. Abbreviations: AK, ancestral karyotype; ASC, agmatoploidy in sex chromosome
