Stag beetles are a family of about 1,200 species of beetles in the family Lucanidae, currently classified in four subfamilies. Some species grow to over 12 centimetres, but most to about 5 cm (2 in).
The false stag beetles (Diphyllostoma) are a group of three species of rare beetles known only from California. Almost nothing is known of their life history beyond that the adults are diurnal and females are flightless; larvae have not been observed.
Scarabaeoidea is a superfamily of beetles, the only subgroup of the infraorder Scarabaeiformia. Around 35,000 species are placed in this superfamily and some 200 new species are described each year. Its constituent families are also undergoing revision presently, and the family list below is only preliminary. This superfamily includes some of the largest beetles extant today, including rhinoceros beetles, (Dynastinae), the Hercules beetle and Goliath beetles.
Dorcus is a genus of beetles in the stag beetle family Lucanidae. Of the over 100 species, most occur in Asia and India; two are found in southern Europe, and two species are from North America. Previously, specimens with serriform teeth on the mandibles and sable pigment were called Serrognathus whereas specimens with but a singular or multiple bulky notches on the mandibles and lustrous sable pigmentation were called Dorcus.
The Lucaninae comprise the largest subfamily of the stag beetles (Lucanidae).
Lucanus cervus, known as the European stag beetle, or the greater stag beetle, is one of the best-known species of stag beetle in Western Europe, and is the eponymous example of the genus. L. cervus is listed as Near Threatened by the IUCN Red List.
The Lucanidae are a family of beetles that include the stag beetles. The family can be further subdivided in a taxonomy. The classification presented here follows Smith (2006), with the exception of the tribal classification within the Lucaninae.

The majority of the species from the genus Cyclommatus are located in Southeast Asia, though some species are found in China and Taiwan as well.

In total, the genus Cyclommatus consists of a total of 134 species, though more are still being discovered to this day.

Mitophyllus is a genus of large stag beetles endemic to New Zealand.
Cyclommatus elaphus is a species of the genus Cyclommatus from Indonesia. It is also the largest species of the genus Cyclommatus and can grow up to a maximum of 109 mm from the tip of the mandibles to the end of the abdomen.
Geodorcus novaezealandiae is a large flightless species of stag beetle in the family Lucanidae. It is the type species and smallest member of the genus Geodorcus. It is endemic to New Zealand.
Apterocyclus is a genus of rare stag beetles in the family Lucanidae. There are about five described species in Apterocyclus. The species of Apterocyclus are found only on the island of Kauai in the Hawaiian Islands, and are the only scarabaeoid beetles native to the Hawaiian Islands.
Apterocyclus waterhousei is a species of stag beetle in the family Lucanidae. The rare, flightless beetle is found only on the island of Kauai in the Hawaiian Islands. It has been reported in several locations on the island in recent years.
Aegus is a genus of stag beetles in the family Lucanidae. Comprising about 260 species in the genus, they are placed in the largest subfamily Lucaninae. They are distributed in South Asia, Southeast Asia and the Pacific countries, but introduced accidentally to many parts of the islands.
