Mastotermes darwiniensis

Mastotermes darwiniensis, common names giant northern termite and Darwin termite, is a termite species found only in northern Australia. It is the most primitive extant termite species. Contrary to common belief, this species does not form mounds as the nests are subterranean and inconspicuous. Colonies will readily occupy and infest decomposing wood but primarily live in a complex subterranean network of tunnels and galleries which they use to travel to new food sites. Colonies may eventually split and form isolated satellite colonies.
