About
The Celebes giant flat stag (Dorcus titanus typhon) is a subspecies of Dorcus titanus from northern and eastern Sulawesi, Buton and Kabaena in Indonesia; it is also called the Sulawesi flat stag. Males measure 60-106.4 mm and females 30-40 mm, placing it among the larger of the 25 subspecies. The surface is matt and the mandibles fairly long and slender. It closely resembles Philippine flat stags with a high inner tooth but can be separated by the shape of the clypeus. Historically, high-toothed individuals from Sulawesi, the Philippines and Sumatra were all placed under ssp. typhon, and the nominate subspecies also occurs in north-eastern Sulawesi. It is very aggressive with a powerful grip and males often kill females, so keep them singly and limit pairing to a short period.
