Meiotic chromosomes of T. rubrofasciata from Central Vietnam. a Metaphase I with C-banding. Eleven autosomal pairs and three sex chromosomes are clearly observed. b Metaphase II with C-banding. Typical spatial configuration of triatomines, with the autosomes forming a ring around the sex chromosomes that are arranged in the center. c Metaphase II. Fluorescent in situ hybridization with 45S ribosomal DNA probe. The 45S rDNA signals are located in the largest autosomal pair (red signals). Scale-bars: a 10 µm; b 10 µm; c 10 µm
