Short summary
A male of the extinct leaf-beetle species Calomicrus eocenicus embedded in Baltic amber is found and compared with an earlier known female. The beetle genitalia are illustrated in detail using X-ray microtomography. The male is smaller than female and has a modified last abdominal segment. The extinct species (about 40 million years old) possesses typical sexual characters which are similar to the characters of extant beetles within the group.
