Abstract/Summary

Despite being a widespread and common species in several parts of the world, Trogoderma angustum (Solier) (Coleoptera Dermestidae) has never been subjected to a thorough morphological examination. Dissection and clear images of body components is vital for subsequent taxonomic studies. Some morphological components have been displayed elsewhere, such as habitus and antennal structure, but clear images of the aedeagus and sternite IX have not been produced. In addition to images of external and internal features, a morphometric analysis of body dimensions is carried out. Body length varies from approximately 2.2 mm to 3.9 mm and there is little overlap in body length between males and females, with males being smaller than females. The effect of aggressive cleansing agents, such as pepsin in HCl and KOH, on delicate components of the aedeagus is discussed.
