Varanus bogerti is part of the subgenera Euprepiosaurus. In the past, animals from this phenotype were described as a subspecies of V. prasinus, with which it is closely related to (MERTENS 1950). SPRACKLAND (1991b) however raised this taxon into species rank, because not only the color (V. bogerti is black, while V. prasinus is green), but differences exsist also in scalation. In V. bogerti, there are also differences in the form of the neck scales to the other sister species V. beccarii. Here they are more pointed than in V. beccarii. The species status might not only be justified by the far away lying distribution areas.
The major color is black, a pattern does not exist. The coloration of the belly side is also black, with some animals also show a little bright grey. The head scales are large and strongly outlined. The scales on the back and on the belly are strongly keeled. 95-99 scale rows are ordered around midbody. The nostril is situated closer to the eye than to the tip of the snout. The tail is round the diameter and is prehensile in the last third (a feature which is characteristic of all members of the prasinus group). Its length is approximately 2 times as long as SVL. The total length can reach up to 85 cm.

The distribution of V. bogerti is restricted to the islands of the D'Entrecasteaux archipelago northeast of New Guinea. (where this species lives, like all members of the prasinus group, arboreal (MERTENS 1950, SPRACKLAND 1991b, 1992a).

Nothing is known on captive care of V. bogerti till now. The reason might be, that all black colores animals from the V. prasinus group were classified as V. beccarii. Therefore all descriptions of captive husbandry of black V. prasinus are published as keeping and breeding success of V. beccarii. However, it also can be, that till now no animals from this species (V. bogerti) were really offered in the trade from this distribution area. An exact taxonomic research of the animals should be done, to clear the species, kept in captivity.
Nothing is published on captive husbandry of this species yet. It might be similar to the care of the other members of the V. prasinus group. Also the incubation parameters should be similar.
