Sperm storage in Centrobolus inscriptus Attems (Spirobolida: Trigoniulidae)
Mark Ian Cooper
Sperm storage organs and their controlling mechanisms were illustrated for Centrobolus inscriptus. The upper reproductive tract with separate insemination duct, spermatheca and oviduct was sectioned. Muscles controlling sperm movement towards the spermatheca were illustrated and identified as muscles of the bursa and gutter apodematique. Sensory apparatus connected to the spermathecae were illustrated.
