Actually true lichtenfelderi (that is former lichtenfelderi lichtenfelderi) are pretty rare in captivity. Only one bloodline exists, originally being collected by a famous russian herpetologist. These are with some people in Europe and probably also USA.
Hainanensis (formerly lichtenfelderi hainanensis) used to be the rarer (and most expensive) of the 2, but recently quite a few have been imported. So now true lichtenfelderi is much more rare than hainanensis
I have seen hainanensis being sold as luii. They 2 are, however, clearly different in size, coloration and body proportions. I should know since I keep and breed both true lichtenfelderi, hainanensis and luii. The real problem is to distinguish true lichtenfelderi and hainanensis. I would say that unless your bloodline can positively be traced back to the origianal true lichtenfelderi bloodline you can safely assume that you have hainanensis. That is also a message to all the people out there assuming the have lichtenfelderi: You probably dont, unless you are able to trace your bloodline back to a reputable breeder who works with the true lichentenfelderi bloodline. This off course has little practical relevance, and it should niot spil the joy and privilege, of working with these animals, but it is best to know stuff like this if natural bloodlines are to be kept clean in captive breeding programs.
Finally to add furter complexity, Grismer destinguishes between 2 different forms of hainanensis - a highland form and a lowland form.
Try to post a pic.
