They enter through the anterior wall of the common genital atrium, latero-dorsally at the right hand side. At the place where the stylets enter, the epithelium of the common genital atrium is reduced to a pseudocuticula. The first accessory stylet lies most ventrally; the prostate stylet lies at the left from the second accessory stylet.</paragraph>
