Taxonomy

In 2011, the genus Serrognathus was reclassified and merged into the genus Dorcus. Previously, specimens with serriform teeth on the mandibles and sable pigment were separated from specimens with a singular or multiple bulky notches on the mandibles and lustrous sable pigmentation which were placed in the genus Dorcus. Latterly, the genus has been resurrected and is once again accepted as valid.

Distribution and habitat

Species in this genus are found in China, Malaysia, Vietnam, Philippines, Korea, India, and Australia.

Threats

In view of their impressive jaws, specimens are often mounted for display alongside with butterflies and tarantulas. Unfortunately, as wild specimens are collected for mounting it should be expected that there will be a corresponding decline in wild populations.
