Hexarthrius melchioritis (Séguy, 1954)

It was first described in 1954 by French entomologist, Eugène Séguy. The species is endemic to northern Myanmar.

Appearance

A large (males 35–71 millimeter), glossy, brown-black stag beetle. The male's jaws are long, quite straight, with an inward-facing tooth just outside the middle, with scattered, small teeth along the inner edge, pointed at the tip. This species is slimmer in build than most other Hexarthrius species. The antennas are quite thin, with a small, six-joint fan. The pronotum is rectangular, much wider than long. The female is completely black, much smaller than the male, with no strikingly enlarged jaws.^[2]

Life cycle

The larvae develop in rotten tree trunks.
