Laniellus langbianis is endemic to montane central Annam, Vietnam, where it is known from Lam Dong and Dak Lak provinces on the Da Lat Plateau. This species is known from only three sites and is likely to have a very small, declining range as a result of the destruction and degradation of its montane evergreen forest habitat. It therefore qualifies as Endangered.
