(Euglenozoa, Euglenida)Transmission electron micrographs (TEM) of Rapaza viridis n. gen. et sp. showing details of the cytoplasm, pellicle and photoreception apparatus. A. Transverse TEM showing the mitochondrion (M-arrowhead), the Golgi body (G-arrowhead) and 16 pellicle strips (arrows). B. Transverse TEM showing the stigma (arrows) and the paraflagellar swelling (Pa). C. Transverse TEM showing the S-shaped frames of the pellicle strips (arrowheads) and underlying microtubules (arrows). D. Sagittal TEM showing the stigma (arrows) and the paraflagellar swelling (Pa). Scale bars 1 μm in A, B and D; 500 nm in C.Back to article page
