We know many people who loves reptiles love to get a leachianus geckos. They are the biggest gecko in the world.

Before you get a leachianus gecko, you should know there are many different locals.

They are all came from New Caledonia just like crested geckos and gargoyle geckos and each type comes from different parts of the New Caledonia.

We want to talk about GT locals in this post.

GT is stand for Grande Terre where is mainland of New Caledonia.

GT locals generally bigger than island geckos and often little more aggresive than island ones.

They can rach up to 15 inches in lengh and over 300 grams. Some GT locals weight up to 450 grams.

Here is the different locals from Grand Terre:

Poindimié

Yate

Mt. Humboldt

Mt. Koghis

Goro

and there is GT type A, B, C and X

Let's talk about deails about each GT locals.

Poindimié

Typical colours are a dark olive green to a dark chocolate brown in the “dark morph” varieties and they usually exhibit little or no white markings. However uncommon, if markings are apparent, they can be thin white lines or rows of lighter spots along the sides of the animal. With age, yellow markings are not uncommon. bodies are typically long an slender.

These geckos are one of the largest recognized forms of Leachianus.

They have very long tails, with an elongated head. These Leachies are known to weigh over 400g while reaching upwards of 15inches in total length.

Yate

These geckos typically most often display a brown or sometimes golden yellow backgrounds. Bodies are typically big and bulky with a very large neck region and often have a thicker, shorter tail.

Markings exhibited in yate can be simple thin, broken white lines, or white dots arranged along the sides. sometimes, you can notice a black spider web like pattering on the sides of their heads.

These are very similar to Poindimié in weight, reaching 400 grams or more but often look more compact and bulky, while Poindimié are longer and more slender animals.

Mt. Humboldt

Mt. Humboldt is one of the hardest locales to identify due to its variability in different specimens. however, there are common factors to identify them. They tend to have an olive-green background with brown markings and white blotches along the sides that are typically in the form of spots rather than solid bars.

The distance between the eyes is narrow in comparison to Yate and their shorter snout can appear almost beak-like.

The largest recorded Mt. Humboldt Leachianus to date has reached just over 420 grams.

Mt. Koghis

Base colour of this local is typically from olive green with browns all the way to jet black. Markings are typically apparent in this local and their Blotches appear in rows along the sides and can be as wide as some insular locals. Because of their jet black pattern, many melanistic morphs come from Mt. Koghis locals.

The best way to identify this local is the enlarged scales along the bridge of the snout. These animals are typically quite bulky, reaching into the 300 gram range.

There were many breeders claiming to have original Mt. Koghis breeding stock:

Conley Dark Morph (CDM)

If you have heard the term CDM this variation originates from Mike Conley (Conoley Dark Morph) and are often very dark and slender in length. These geckos are long with long tails and can often have minor white spots on their sides but never white barring. Females are incredibly hard to come by so this variation is often bred with other locales.

Treoger Mt. Koghis

This variation was bred in Europe by the late Michael Treoger and most of this stock was imported to the USA upon his demise and joined the collection of Allen Repashy and PDV. This variation is defined by white barring on many of the examples.

Friedel Line Mt. Koghis

Another European Breeder, Bodo Friedel, focused on another Mt. Koghis line, that is defined by barring or speckling in a white or light pink colouration. Body is shorter and stockier than other locales, similar to Yate body-type, while the head is a bit broader. There is also a Dark Form of this GT Leachianus, as it the case with all Mt. Koghis varieties

GT type A

Animals from eastern forests including Yate, Poindimie and possibly Mount Humboldt. Yate forms are lighter than Poindimie forms. These tend to have no to few small light (whitish) rounded blotches. Head is flattened. Snout scales on adults tend to be uniform. Up to 15 inches.

GT type B Geckos of undetermined origins that were bred and imported as Grande Terre animals from Europe. Most are patterned with large white blotches or bars. Some could be leachianus x henkeli crosses. Adult size is typically between 12.5 and 14 inches.

GT Type C Giant patterned geckos with white blotches that are descendants of a collected pair owned by Philip Tremper. Generally one of the biggest GT locals. These can reach 13 inches snout-to-vent length and up to 17 inches total length.

GT Type X

GTX means cross breeding between GT locals. For example, GTA x GTC, Yate X TypeA, or TypeB x Mt Koghis.
