Description

A cryptic species from the forested regions of southern Westland. The broad-cheeked gecko is similar in appearance to other southern Mokopirirakau exhibiting the W or H-shaped marking running along the upper surfaces, as well as the V-shaped marking between the eyes. The colouration on the upper surfaces is variable ranging from shades of brown through to grey, often with yellow, red or pinkish splotches. The ventral surfaces are much lighter in colouration often being a greyish colour but can be flecked with yellow and cream, with dark speckling, the undersides of the extremities are often lighter in colouration than the body. The mouth lining and tongue are bright orange in colouration. As per the name the cheeks may appear quite broad when viewed from above.

Life expectancy

Unknown, but likely to be similar to other southern Mokopirirakau species.

Distribution

Restricted to Westland, but the distribution limits of this species are poorly understood. Known to occur between Tai Poutini National Park and the Paringa River. 

Ecology and habitat

A nocturnal, and arboreal species. It is known to inhabit the wet coastal forests in the Ōkārito region but may occur well into the subalpine region.

Social structure

Unknown.

Breeding biology

As with other Mokopirirakau, females are likely to produce 1-2 young, either annually or biennially.

Diet

Most likely to be an omnivore as with the other Mokopirirakau, taking both invertebrate prey, as well as the fruits and nectar of a variety of plant species.

Disease

Is a host for gecko mites.

Conservation strategy

The broad-cheeked gecko is listed as "Nationally vulnerable".

Interesting notes

Broad-cheeked geckos get their common name from the width of their heads, which supposedly have slightly wider proportions than our other Mokopirirakau. The TAG name refers to their distribution, with their stronghold being centred on Ōkārito.

One of the original broad-cheeked geckos was discovered when it was found in the backpack of a hunter, who returned from a high-elevation area near Paringa. This gecko was briefly kept in captivity, then sadly passed away and was donated to a museum.

The broad-cheeked gecko sits within the western clade of the Mokopirirakau genus, with the Cascade gecko and Open Bay Islands gecko being their closest relatives within the group.
