Odontolabis cuvera sinensis
Etymology
The Latin species name Cuvera comes from a mythical king of riches (Kubera or "Kuvera") who lived in the Himalayas.
List of subspecies
Description
Odontolabis cuvera can reach a length (mandibles included) of about 43–90 millimetres (1.7–3.5 in) in male, of about 41–51 millimetres (1.6–2.0 in) in females. Moreover, males have a conspicuosly elongated and large pair of mandibles. The basic color of the body is black. Elytra have broad orange margins on the outer edge. The female closely resembles the male in coloration but it lacks long mandibles.
The remarkably disparity between male and females (sexual dimorphism) evolved through sexual selection for securing mating females. The males have also three morphological forms with variations in the size of their mandibles. These three alternative phenotypes (male trimorphism) in the types of male weapons are considered conditional reproductive strategies.
In the subspecies Odontolabis cuvera sinensis elytra are almost completely black, with a small orange border. These beetles can reach a length of about 80 millimetres (3.1 in).
Life cycle
The females lay their eggs into leaf litter substrate and rotten wood. Larvae build their cave system and stay inside it, feeding for several years on rotting wood.
Distribution
This beetle is native to southeast Asia and it is present in Bhutan, China, India, Laos, Myanmar, Nepal, Thailand, Viet Nam.
