It is likely that this species is actually a species complex of multiple different species that have been diverging since the Pliocene, and diverged from the V. indicus species complex 4.7 million years ago.[5]
Peach-throated monitors are endemic to New Guinea and surrounding islands such as Biak, Salawati, Yapen, Normanby, and Waigeo.[5] It occurs in rainforests at altitudes of 0–900 m (0–2,953 ft).[1]
Peach-throated monitors grow up to 120 centimetres (3.9 ft) in total length (including tail). The colour of the throat is white-yellow to red, to which one of its common names refers.
The specific name, jobiensis, which is Latin, means "from Jobi". Jobi is the island also known as Yapen, which is the type locality of this species.[4]
