• Phylogeny and ecology of the Cimicidae: Bedbugs, or Cimicidae, copulate in a spectacular way: males pierce the cuticle of the female and transfer their sperm into the female body (traumatic insemination). In at least two cimicid species this reproductive mode has been shown or implicated to result in sexual conflict, a process that is known to accelerate the rate of evolutionary change. The aims of this study are a) revealing the molecular phylogenetic relationship within the Cimicidae and b) to reconstructing the evolution of sexual organs, particularly the female copulatory organ which seems to ameliorate the damage caused by the male.
