y a-t-il une difference entre " dark morph" et "cf Mt Koghis" ?
(je n'en suis pas sûr )

apparemment il y aurait 2 ou 3 "type" ou localité.

C'est la même chose
Il existe également des morphs spécifiques aux localités insulaires Nuu Ana et Nuu Ami,au large de l'île des Pions

Moi non plus mais cet extrait de discussion par P de V himself me semble interessant...(surtout la fin... )

"This confirms the confusion associated with what I have categorized as type B. According to Henkel and Seipp's book, type B is smaller and found in a different niche than Mt. Koghis dark morphs. You need to realize first of all that for now we are just talking about different morphotypes. If in the same geographical area there is no reason why interbreeding could not occur. One possibility is a niche/genetic segregation based on competition. Larger animals more successfully compete for higher more prime niche. Smaller animals adapt to lower less prime niche. I'm saying this because in leachianus, size definitely makes for more successful intraspecies competition even if it is not ideal as an adaptation to a particular habitat.
That being said, if you examine a vegetational map of Grande Terre, you will find that it consists of forest islands often separated by prairie(west) or maquis ( scrub brush with small trees). Each of these geographically and genetically isolate GT populations. The best defined GT morphotype is the Yate GT type A originally collected by Frank Fast in the small Yate forest. From Mt Koghis, you do have a line of animals with dark background color and a small amount of white pattern that achieve large size. If line bred those characteristics are maintained. They are distinct from Type C which is highly patterned and grows larger than any other GT morphotype collected to date. For now I consider the original wild collected pair owned by Philip Tremper as the original captive representatives of type C. There are other differences including snout scalation that may help distinguish morphotypes but because little attention was paid to morphotypes in the past, it is difficult to assess the origins or morphotype of GT animals in captivity.
With GTs. the total number of animals collected from any forest location was so small ( a single pair in some cases) that a real future problem is a decline in vigor and fecundity of captive lines. We suspect from some island populations that inbreeding depression can occur. Unless additional collected animals are introduced to captive gene pools, then line breeding of GTs may ultimately not be a ideal course."
