About
The lunifer long-jawed stag (Cyclommatus lunifer) ranges from Borneo, Sumatra and the Malay Peninsula into south-eastern Myanmar, and was described in 1905. The specimen records held by GBIF cluster in Sabah and Pahang in Malaysia and in Indonesia. The BE-KUWA captive record is 55.2 mm against a wild record of 53.3 mm, small for the genus but a sign that captive lines are productive, since breeders have passed the wild figure. Cyclommatus visit flowers of herbaceous plants rather than sap runs, and the males fight over females and feeding sites out on thin twigs and grass stems. Care follows the genus: a firmly packed set combining a soft egg-laying log with fine fermented substrate. Condensation inside the box is fatal, so keep it cool and well ventilated. Larvae do not take to fungus bottles and are reared on fermented substrate.

Notable localities
Sabah, Borneo (Malaysia)Pahang, Malay Peninsula (Malaysia)Sumatra (Indonesia)
The captive record of 55.2 mm already exceeds the wild record of 53.3 mm, and the projected maximum of 56 mm is close behind, so there is little room left to grow this species larger.
