| The ultrastructure of male copulatory organs having a stylet has been studied in some genera of the Proseriata. Within the Monocelididae there was a variety of stylet-like hard structures. The stylet in <i>Monocelis fusca</i> was a differentiation of the basement membrane of the epithelium lining a penis-like muscular papilla. The penis papilla in <i>Ectocotyla</i>consisted of circular muscles surrounded by a thickened basement membrane and an epithelium. <i>Archilopsis sp.</i> and <i>Archilina sp.</i> with a duplex copulatory bulb, had a stylet within a spiny cirrus.
