It is endemic to Papua New Guinea and is only known from its type locality, Mount Elimbari in the Simbu Province.

[1][2] This species was originally described in the genus Albericus,[3] named for Alberich, the dwarf in Scandinavian mythology and Richard Wagner's opera cycle Der Ring des Nibelungen.

[3] The specimens in the type series (sex unspecified) were originally reported to measure 14–16 mm (0.55–0.63 in) in snout–urostyle length.

[3] Later examination of a subset of these, of which five are females and one is a male, gave much larger size, 18–21 mm (0.71–0.83 in) in snout–vent length.

[5] The ventral surface is reddish, yellowish, or whitish, with variable spotting or else uniformly dark.
