Segmented 3D model of Bocchus rex sp. nov., female, paratype (= specimen 2) based on SR-µCT data (perspective view; cf. Suppl. material 1: Video S1; parts of the left antenna and the tarsus of the right hind leg are outside of the dataset) a, b ventral view c, d dorsal view e, f dorsolateral view g, h lateral view i, j frontal view. The cuticular elements in a, c, e, g, i are depicted in various shades of brown, whereas the cavity of the wasp in the amber is shown as being semi-transparent. The partially preserved optical ganglion complex is shown in blue, the potential brain regions or head muscles in purple, and the muscles (in the thorax, the legs and the metasoma) in red, whereas the cuticular elements in b, d, f, h, j are semi-transparent and the cavity in the amber is omitted.
