Figure 8
Transmission electron micrographs (TEM) of non-consecutive serial sections through the posterior part of the nucleus of Bihospites bacati n. gen. et sp. Figures 8A-D are presented from anterior to posterior. A-C. TEMs showing the rod (r) and the folded accessory rod (ar) nestled within indentations in the dorsal and ventral sides of the nucleus. The ventral part of the accessory rod runs close to the main rod for most of its length and extends toward the flagella on the ventral side of the cell. N = nucleus; D, dorsal; L, left side of the cell; R, right side of the cell; V, ventral; Images are viewed from the anterior side of the cell. D. TEMs showing the main rod (r) and the accessory rod (ar) reaching the posterior end of the nucleus (N). The main rod consists of parallel-arranged lamellae. Most of the nucleus and the main rod have disappeared from the section. The accessory rod (ar) consists of striated fibres that wrap around the main rod and the nucleus (bars = 2 μm).
