The lace monitor is monotypic; no subspecies are recognised.However, genetic analysis of its mitochondrial DNA (mtDNA) across its range revealed three main clades: a north Queensland clade separated by the Burdekin Gap from a clade spanning from southern Queensland through inland New South Wales across the Murray–Darling basin and into southeastern South Australia.
Yellow-spotted monitor (left), lace monitor (right) This ground dwelling monitor species, somewhat resembles the widespread sand goanna (Varanus gouldii).Large, dark spots appear in rows along its back, becoming especially distinct at the center of the back where they are interspersed with smaller and paler spots.
Varanoidea is a superfamily of lizards, including the well-known family Varanidae (the monitors and goannas). Also included in the Varanoidea are the Lanthanotidae (earless monitor lizards), and the extinct Palaeovaranidae. Throughout their long evolutionary history, varanoids have exhibited great diversity, both in habitat and form.
Monitor lizards are considered unique among animals in that its members are relatively morphologically conservative, yet show a very large size range. [19] However, finer morphological features such as the shape of the skull and limbs do vary, and are strongly related to the ecology of each species. [20] [21]
Bites on the hand by Komodo dragons (V. komodensis), perenties (V. giganteus), lace monitors (V. varius), and spotted tree monitors (V. scalaris) have been observed to cause swelling within minutes, localised disruption of blood clotting, and shooting pain up to the elbow, which can often last for several hours.

The rock monitor (Varanus albigularis) is a species of monitor lizard in the family Varanidae. The species is endemic to Sub-Saharan Africa , where, on average it is the largest lizard found on the continent.
In some places, however, the ranges of Gould's monitor, V. g. flavirufus and the Argus monitor overlap. The similarities between the species and their close proximity frequently cause confusion. The sand monitor is a relentless forager. It is diurnal, meaning most of its activities take place during the day. Anything smaller than itself will be ...
The black-headed monitor or black-tailed monitor (Varanus tristis) is a relatively small species of monitor lizards native to Australia. It is occasionally also called the mournful monitor , freckled monitor ( Varanus tristis orientalis ) or the racehorse monitor , [ 2 ] a name it shares with the Gould's monitor due to their exceptional speed.
