Morphology of reproductive accessory glands in eight species of blood-feeding Hemiptera (Hemiptera, Reduviidae) insect vectors of Chagas disease

► Reproductive accessory gland morphology is described in eight species of Chagas disease vectors. ► Comparison employs the same morphological techniques to describe living tissue. ► Males possess an accessory gland complex having the same number and types of glands. ► Females have spermathecae unique to the species providing a mechanism for cryptic female choice. ► This morphological comparison suggests that control methods targeting male reproduction may affect more than one vector species.
