Annotation	The neo-X and neo-Y sex chromosomes of Dysdercus albofasciatus represent a unique model for the study of early stages of sex chromosome evolution since they retained the ability to pair and recombine, in contrast to sex chromosomes in most Heteroptera. Here we examined structure, molecular differentiation, and meiotic behaviour of the D. albofasciatus neo-sex chromosomes in comparison with the ancestral X0 system of D. chaquensis and D. ruficollis, using rDNA-FISH, GISH, Zoo-FISH with the ancestral X chromosome painting probe, and immunostaining against the cohesin subunit SMC3. Our results support the hypothesis that the neo-X chromosome evolved by insertion of the original X chromosome into the NOR-bearing autosome in an ancestor carrying the X0 system. The homologue of this NOR-autosome became the neo-Y chromosome. A subsequent inversion followed by transposition of the NOR located on the neo-Y onto the neo-X chromosome resulted in the present neo-X/neo-Y system in D. albofasciatus.
