Synsperm of Kambiwa neotropica. TEM. A Cross-section through the anterior pole of the synsperm. Note the membranous inner structures as well as the dense secretion sheath and the tile-like seminal secretions. B, C Cross sections through synspermia showing the flexibility of the aggregate as well as of the various internal structures. D Detail of the layering of internal secretions and filamentous structures surrounding the sperm cells within the synsperm. E Sperm cells within the synsperm. Note the position of the nuclear canal within a fine projection. F Detail of the filamentous structures beneath the secretion sheath
