Reisinger's tree monitor, Yellow tree monitor
Varanus reisingeri, known commonly as Reisinger's tree monitor and the Yellow tree monitor, is a species of monitor lizard in the family Varanidae. The species is endemic to Indonesia. It was at one point at least considered an allopatric insular subspecies of the green tree monitor, due to physical and genetic similarities.
The specific name, reisingeri, is in honor of Manfred Reisinger, a German naturalist and reptile breeder.
