Histology and morphology of the male reproductive system of Spilostethus pandurus is described using light and scanning electron microscopy. The male reproductive system consists of two testes, in which different stages of spermatogenesis are observed, two vasa efferentia, two seminal vesicles, two tubular vasa deferentia, two accessory glands (mesadenia), ejaculatory bulb and a single muscular ejaculatory duct which opens via the aedeagus. Knowledge of the basic reproductive morphology and histology can be used to infer function and provide key information for future research into reproductive behaviour, evolution and physiology in Hemiptera.
