Fig. 8

The central nervous system and midgut in the trunk of Pallenopsis cf. aulaeturcarum (Pallenopsidae). Reconstructions of the CNS (3D volume rendering, green) and midgut (3D surface, magenta) based on a µCT scan of an adult male. The black arrows point to a small lateral protrusion of the cheliphore diverticulum. Asterisks indicate the incompletely reconstructed optic nerve (insufficient resolution). For better pattern visualization, all major nerves of the right body half were virtually removed in A (right side) and B. The palpal nerve is labeled in quotation marks (“pan”) as it could not be traced into the reduced palp but projects to the cheliphore. 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. Right side: CNS and midgut. The white arrow highlights a small lateral midgut protrusion near the subesophageal ganglion. For reference, unreconstructed dorsal parts of the trunk are shown in transparent gray
