Woodworthia (the ‘common geckos’) are small to medium sized nocturnal geckos. Rostral scale does not extend to nostrils, or rarely in very narrow contact. Snout to ear distance ≥ eye to ear distance. Toes have expanded pads. Most Woodworthia are terrestrial (rather than arboreal / tree climbing), and inhabit coastal scrub, boulder and scree deposits to rock crevices and alpine bluffs. They are tolerant of conspecifics and other lizard species and have been observed in small to large aggregations, including with other gecko species and skinks.
Recent taxonomy suggests that most captive animals are likely to be hybrids, mostly of Raukawa geckos and Canterbury geckos. Aside from these two species, there is very little known about the ecology and behaviour of the other Woodworthia geckos. It is recommended that captive Woodworthia of known origin are not mixed with other Woodworthia from different locations or unknown origin.
We have separate specific pages for the following species: Woodworthia brunnea, Woodworthia chrysosiretica, and Woodworthia maculata.
The following 'compare and contrast' table has been collated using information from Jewel (2011).
|Species||Colouration / description||Region / habitat||Mouth||Eyes||Feet||Size|
|Raukawa / common gecko (W. maculata)||Dorsal (upper) surface largely grey or brown with irregular markings, including black, white, yellow/orange, and olive green patches. Marking are usually transverse, however, longitudinal markings can be found in some specimens or common in some populations. A canthal stripe may or may not be present.||North Island east coast. Generally coastal.||Mouth lining pink, tongue pink with grey tip.||Brown, can be yellowish or greenish brown.||Toes have 9-12 lamellae.||<82mm SVL, usually smaller.|
|Waitaha gecko / brown gecko / Canterbury gecko (W. brunnea)||
Dorsal (upper) surface brown, though some individuals are grey or olive. Dorsal surface marked with bright chevron stripes, blotches, lateral or longitudinal bands. Large dark patches are common, particularly on the tail (if intact). Ventral (lower) surface commonly pale and uniform in colour, with occasional individuals sporting a spotted belly.

Inland sites from north Otago to southern Marlborough.
Inhabits screes, rock piles and scrubby vegetation. Very few records from beech and kanuka forest.
|Mouth lining pink, tongue pink- may have grey tip.||Greenish or brown. May have a bluish edge.||Toes have 9-12 lamellae.||50-65 mm SVL.|
|Pygmy gecko (W. 'pygmy')||
Very small gecko. Head short and deep.
Dorsal surface light olive-grey, often with many paler blotches. Often two rows of blotches or bands.
Rangitata mountains area.
Inhabits screes and rock piles, often in scrubby vegetation or grassland in lower alpine areas.
|Brown with olive mottling.||Toes have 7-8 lamellae.||38-44 mm SVL.|
|Kawarau gecko or Cromwell gecko (W. 'Cromwell')||Grey, brown or olive with prominent pale blotches or bands. Occasionally may have stripes. Ventral surface often heavily speckled.||
Inhabits schist rock formations and associated scrubby vegetation.
Tongue: pink with grey tip
|Greenish brown to dark brown. May have greenish flecks.||Toes have 9-12 lamellae.||48-78 mm SVL.|
|Central Otago or schist gecko (W. 'Central Otago')||Brown / grey gecko with paler blotches, bands or stripes.||
Ranges and lowland of central Otago.
Inhabits schist rock formations and associated scrubby vegetation.

|Short-toed gecko or southern mini gecko (W. 'Southern tmini gecko')||Light olive to olive brown. Uniform colouration or with faint pale stripes. A relative of the Goldstripe gecko from the North Island.||
Southern South Island.
Inhabits scree, boulder fields and rock crevices in subalpine and alpine areas.
|Mouth lining pink, tongue pink with grey tip.||Brown||Toes have 10-13 lamellae.||48-60 mm SVL.|
|Korero gecko or Otago large gecko / Otago Southland gecko / Danseys Pass gecko** (W. 'Otago large')||

|Southland to North Otago||Mouth lining pink, tongue pink- may have grey tip.||Brown, olive brown||Toes have 8-12 lamellae.||73-85 mm SVL.|
* The taxon previously referred to as the Kaikouras gecko is now placed within the Minimac gecko species concept, we have provided a separate description for the Kaikouras as populations differ slightly in appearance.
**Danseys Pass gecko name refers to a population of korero gecko in the Kakanui Mountains.
Note: dorsal = upper surface; ventral = lower surface; SVL = snout to vent length
