Spermatozoa of Sergentomyia minuta (which had been collected near L'Aquila, Italy) were examined by light, scanning and transmission electron microscopy. The spermatozoon was seen to have a head and a tail. The first was characterized by an acrosomal complex with a thin space containing granular material which was interpreted as a perforatorium. The tail contained a 9+9+0 axoneme and one mitochondrial derivative. These results are compared with the sperm ultrastructure of other Diptera, particularly Psychodidae.
