Study: Chinese Ceruchus morphological revision
Examination of type material of most Chinese species of the stag beetle genus Ceruchus MacLeay, held at AHU, MNHN and SHNU, to review and refine the generic characters of the genus. Morphological observations and measurements were made under an Olympus SZX7 stereomicroscope and documented photographically. The study described one new species, Ceruchus ahualuo, and produced an updated diagnostic key to all known Chinese species.
