Abstract
Dorsal abdominal glands (DAG) in the nymphs are one of the apomorphic characters of Heteroptera. In some taxa of Enicocephalomorpha and Cimicomorpha, and numerous taxa of Pentatomomorpha, these glands are known to persist in the adult. Comparative examination in Reduvioidea (Cimicomorpha) in this study established that ostioles, reservoirs and glandular ductules are present in the majority of adults in Reduviidae, but are absent in Pachynomidae. Number and location of DAGs for 79 species of Reduviidae in 20 subfamilies are summarized here and cuticular modifications surrounding the ostioles of the dorsal abdominal glands are documented. The DAGs are illustrated using light, scanning electron and confocal microscopy, and noteworthy differences between the taxa studied are pointed out. (© 2006 WILEY-VCH Verlag GmbH & Co.
