The central nervous system and midgut in the trunk of Rhynchothorax australis (Rhynchothoracidae). Reconstructions of the CNS (3D volume rendering, green) and midgut (3D surface, magenta) based on a µCT scan of an adult female. Asterisks indicate incompletely reconstructed portions of the optic nerve (insufficient resolution) and damaged regions of leg nerves. For better pattern visualization, all major nerves of the right body half were virtually removed in A (right side) and B. A Oblique antero-lateral view. Right top corner: overview of the specimen. Left side: complete CNS and midgut reconstruction. Right bottom corner: anterior portion of the CNS and eyes. B Lateral view of the CNS with and without the midgut structures (top and bottom, respectively). For reference, unreconstructed parts of the right body half are shown in transparent gray. C Ventral view. Left side: CNS in grayscale. The black arrowheads point to the intersegmental nerves. The white arrowhead indicates the origin of the posteriorly projecting proctodeal nerve. Right side: CNS and midgut. For reference, unreconstructed dorsal parts of the trunk are shown in transparent gray
