The spermatozoon of Toxorhynchites brevipalpis conradti Gruenberg is long and filiform. It contains an anterior nucleus, an axoneme of the 9 + 9 +“1” pattern and two mitochondrial derivatives. Comparison of our observations with bibliographical data shows that spermatozoon ultrastructure is homogeneous in the family Culicidae (Culicinae, Anophelinae and Toxorhyn‐chitinae). The 9 + 9 +“1” pattern of the sperm axoneme may be considered a synapomorphy of the Culicidae.
