Ovipositor muscles supporting the venom and reproductive system of Lariophagus distinguendus. a–c SR-µCT images of a virtual slices through the anterior part of the ovipositor (a,b sagittal view, left is anterior, c transversal view) highlighting the muscles supporting the venom and reproductive system, the venom gland reservoir and its orifice, the Dufour’s gland and its duct, and the common oviduct (the colour labels correspond to Fig. 6 and Additional file 4). d Light microscopical image of a semithin cross section through the ovipositor. The ventral 2nd valvifer-venom gland reservoir muscle with its Z lines is clearly visible.
