The new monitor lizard, named ‘Torch’ for its bright orange head which tops a black body, reaches almost four feet in length, a little smaller than the other recently-discovered monitor Varanus bitatawa from the Philippines. Researchers say the torch monitor is in fact a close relative of Varanus bitatawa . Inhabiting the coastal sago palm mangrove forests on Sanana, the torch monitor is the only monitor species to have evolved red coloring.

Researchers believe that since no predatory mammals live on the eastern side of Wallace Line—a biological demarcation first set out by explorer-biologist Alfred Russell Wallace—big reptiles like the torch monitor, which feeds on small animals and carrion, have taken the place of top predator.

“There are more [monitor] species there, doing more different things ecologically than in Africa or South and Southeast Asia, where competition and predation by mammals tend to keep monitor lizards down. East of Wallace’s Line in Indonesia, New Guinea, and Australia, monitor lizards are on the top of the heap. It emphasizes again how little we know about some tropical regions, to find an animal so strikingly colored and so large only last year,” says Sam Sweet, a professor in the department of Ecology, Evolution and Marine Biology at UCSB, in a press release.

An expert on monitors, Sweet worked Valter Weijola, a graduate student at Abo Akademi University in Turku, Finland, to describe the species. Weijola discovered it a year ago.

The largest family member of the monitor lizards is the infamous Komodo dragon, also endemic to Indonesian islands.

ScienceDaily (May 17, 2010) — German scientist André Koch from the Zoological Research Museum Alexander Koenig (ZFMK) in Bonn together with his supervisor Prof Dr Wolfgang Böhme and another colleague have described two new monitor lizard species (Varanus spp.) and one new subspecies from the Philippines in a recent article. Their comprehensive study of the Philippine water monitors revealed, that despite the recently discovered new and fruit-eating monitor species from the main island of Luzon by an American-Philippine research team, the real diversity of these giant lizards in the archipelago has not yet been understood: here.
