Ultrastructural study of spermatozoa was made for five species and four genera in two families of Nepomorpha, Belostomatidae and Nepidae (Insecta: Heteroptera). The following five synapomorphic relationships were recognized for the fine structures of spermatozoa: 1) Nepomorpha have acrosome displaced to a lateral position with respect to the nucleus; 2) the centriole adjunct is well developed in mature spermatozoa; 3) each of the two mitochondrial derivatives contains two or three crystalline bodies; 4) the derivatives are linked to the axoneme by two bridges at the level of doublets 1 and 5; and 5) accessory bodies are absent in this group. A brief comments on the phylogenetic relationships among three families (Belostomatidae, Nepidae and Notonectidae) of Nepomorpha is given.
