[2][3] The distribution of V. macraei is restricted to the island of Batanta, on the northwestern tip of the Vogelkop peninsula of Irian Jaya of Indonesia.

The tip of the snout is light blue and the lower jaw is white with uniform green scales along the neck, forming a v-shaped pattern.

A single distinct blue scale row stretches from the lower angle of the eye to the upper edge of the ear.

Like all members of the prasinus-group, with 22–23 more or less symmetrical blue rings, the tail is prehensile and about 1.95 times as long as the snout-vent length (SVL).

[5] Currently no studies have been published on the matter, however the diet of V. macraei is likely primarily made up of (in order) stick insects, orthopterans (grasshoppers, katydids and crickets), moths, beetles, smaller lizards, small eggs, and the occasional berry.

[5] As recently as a decade ago, only five species comprised the tree monitor group: Varanus prasinus, V. beccarii, V. bogerti, V. keithhornei, and V. telenesetes.
