TEM study of B. aequans adults aged 6-8 days showed that the seminal vesicle and ejaculatory duct are lined by syncytial epithelium with numerous lamellate processes; the cirrus and genital pore are covered by a spineless tegument similar to the body tegument; the testes contain tailed spermatozoa, which developed from biflagellate spermatids whose flagella (9 and 1) fused with the median cytoplasmic process; and the lumina of the seminal vesicle, ejaculatory duct and cirrus are filled with spermatozoa.
