The flexor rotates the ventral portion of the clasper apodeme dorsally and posteriorly and brings it in apposition to the body of the clasper. Thus, the apodeme, which is in a twisted position when the male is at rest, becomes straightened in copula and folded back toward the medial surface of the clasper. This process results.
