Since being separated from Hoplodactylus maculatus by Hitchmough (1997), populations currently assigned to this species have been subject to frequent informal taxonomic redefinition. Currently the species is known as Woodworthia sp. 'Otago large' or ‘Otago/Southland large gecko’. However, other names also include H. sp. ‘Eastern Otago’ (= populations from eastern Otago and Southland, plus the Central Otago gecko); H. sp. ‘Western Otago’ (= populations from the Dunstan Mountains and Old Man Range westwards); H. sp. ‘Otago’ and H. aff. maculatus ‘Otago’ (excluding populations from Kye Burn, but including the Central Otago gecko); H. sp. ‘Danseys Pass’ (= populations from Kye Burn). Other names are the 'maxi', 'Kakanui/Horse Range' and 'Southland' (Hitchmough 1997). Jewell (2008) proposed the common name, korero gecko. This is in reference to the active vocal behaviour of this species. The tag name 'Otago large' is a reference both to the southern location of the species and the larger size than other congeners in the area.
The Otago large gecko has a complex clinal variation, involving size, colour, build and scalation (Hitchmough 1997, Jewell 2006, Jewell 2008). The following major 'forms' are recognised:
Korero gecko; Otago Large gecko
A medium to large gecko (63–90 mm SVL (usually 73–80 mm, but frequently reaching 85 mm at high altitudes) and 17.5 g (Girling 1993, Cree & Guilltte 1995, Hitchmough 1997, Jewell 2006, R. Hitchmough pers. comm. in Jewell 2008). Body proportions vary widely across range from medium to very robust. The species is highly variable and may be grey, olive-grey, brown, or deep pinkish-brown. Markings are generally banded or blotched, sometimes with partial stripes. Fully striped individuals are rare in most areas, but frequent in the Garvie Mountains and the Kakanui Range, and have been recorded on the Taieri Ridge. The eye may be grey, brown, green or yellow. Mouth colour is pink. There is considerable structured geographic variation (Jewell 2006). Varies considerably in build and in the width of the toepads. Lamellae curved. Distal phalange may be narrow or tapering. The feet often appear large in size, especially in western areas.
