Varanus doreanus doreanus Meyer 1874
Varanus doreanus finschi Bohme, Horn &
The rediscovery of the blue-tailed monitor is the latest in an exciting series of discoveries by Wolfgang Bohme and Georg Horn. Described and forgotten. the holotype had been destroyed by a wartime bomb, but the precise description given by Meyer allowed the recent workers to identify it as identical to their new-found species (Bohme et al 1994). The bluetailed monitor appears to be closely related to the mangrove monitor, V.indicus. and can be distinguished from this and other, similar, species by the smaller. more numerous, scales over the back , a brightly marbled underside, white tongue and a striped tail. Specimens are known from all over New Guinea and the islands of New Britain and Biak. The blue-tailed monitor appears to be restricted to intact forests and has been seen foraging on the ground. When threatened they do not take to water, as is almost invariably the case with the mangrove monitor. They can be tempted out of hiding with carrion or turtle eggs. V.doreanus finschi from the island of New Britain has a marked, rather than white, throat.
Blue-tailed monitors are exported to Europe and North America, usually under the name Kalabeck's monitor. In captivity they require a spacious enclosure that allows them to climb and a warm, humid climate.
