Choerophryne valkuriarum

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][4] Menzies named the Albericus species he described after Alberich's companions in the mythodology, in this case the valkyries.[3]

Choerophryne valkuriarum is similar to other former Albericus, although it is smaller that most others: the specimens in the type series measure 14–20 mm (0.55–0.79 in) in snout–urostyle length.[3] Their sex was originally unspecified but later examination has shown all of them to be males.[5] The limbs are relatively short. Some specimens have a mid-dorsal line or lumbar ocelli.[3]

The male advertisement call consists of single "clicks", uttered once or in irregular series with rates up to 120 notes per minute. The call has no musical quality.[3]

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. It has been found in a few rural gardens but does not tolerate severe habitat degradation. Development is presumably direct;[1] i.e., there is no free-living larval stage.[6]

This species is very abundant but can be locally threatened by habitat degradation. It occurs in the Mount Kaindi Wildlife Management Area.[1]
