X-ray microtomography generated 3D models of Aphanerostethus with the right elytron removed, revealing differences in the length, width, and venation of the hindwing (as shown here, the hindwing is affixed to the inner surface of the elytron in most specimens). A lateral view of the full body is shown below each close-up for reference. The red, blue, and yellow arrows indicate the base, midpoint, and apex of the hindwing, respectively A Aphanerostethus bifidus sp. nov. (JHLHY_DAR_092) B A. decoratus sp. nov. (JHLHY_DAR_079) C A. japonicus sp. nov. (JHLHY_DAR_041) D A. magnus sp. nov. (JHLHY_DAR_032).
