[2] The preferred natural habitats of T. montana are grassland and shrubland.

[1] Adults of T. montana have a snout-to-vent length (SVL) of 4.5–5.5 cm (1.8–2.2 in).

Compared to other species of its genus, the head is shorter, and the tail is longer.

[2] Nota bene: A trinomial authority in parentheses indicates that the subspecies was originally described in a genus other than Tropidosaura.

The subspecific name, rangeri, is in honor of Gordon Ranger who collected the holotype.
