Dorso-abdominal scent glands and metathoracic evaporatoria in adults of central European Rhopalidae (Hemiptera : Heteroptera), with a discussion of phylogeny and higher systematics

The reservoirs of dorso-abdominal scent glands and the occurrence of the me tapleural scent gland evaporatoria in the adults of nine central European a nd one North American species in the family Rhopalidae (Hemiptera) were stu died. All published data about the persistence of the dorso-abdominal scent glands in rhopalid adults are reviewed, and systematic and phylogenetic im plications are derived from the patterns of variation.
