Abstract
The authors describe a new model of sperm axoneme, the "9 + 9 + 3," which is characteristic of simuliid Diptera. Each of the three central tubules has a row of very long side projections rich in ATPase activity, but the flagellum lacks the central sheath. Sperm motility is normal, like that of sperm having a "9 + 9 + 2" axoneme model and accessory bodies. © 1974 Academic Press, Inc.
