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

[2][4] Menzies named the Albericus species he described after Alberich's companions in the mythodology, in this case the valkyries.

[2] Choerophryne valkuriarum is similar to other former Albericus, although it is smaller than most others: the specimens in the type series measure 14–20 mm (0.55–0.79 in) in snout–urostyle length.

[2] The male advertisement call consists of single "clicks", uttered once or in irregular series with rates up to 120 notes per minute.

[2] Choerophryne valkuriarum occurs in mid-montane rainforest and on the forest edge at elevations of 2,000–2,930 m (6,560–9,610 ft) above sea level.
