Forelimbs are moderaterely robust; hind limbs are long and have webbed toes.

[2] Telmatobius chusmisensis is known from discrete populations at elevations of 1,800–4,500 m (5,900–14,800 ft) above sea level.

[1] At the type locality, T. chusmisensis were collected from a small, slow-moving stream in a semi-desert area.

Adults were encountered below stones and tadpoles below aquatic plants along the banks of the stream.

[1][2] As a species found in a generally arid area and confined to aquatic habitats, its distribution is naturally fragmented.
