Etymology
editThis 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, although rhenaurum is Latinized form of Rheingold.[2]
Description
editThe two specimens making the type series measure about 15 mm (0.59 in) in snout–urostyle length.[2] Their sex was originally unspecified but later examination has shown them to be males.[5] Choerophryne rhenaurum is similar to Choerophryne tuberculus but has a broader snout and advertisement call that has much longer pulse length (470–510 ms versus 250–350 ms in C. tuberculus). The call could be characterized as a "splutter".[2]
Habitat and conservation
editChoerophryne siegfriedi is known from rainforest.[1] The altitude of the type locality is variously given as 1,200 and 1,520 m (3,940 and 4,990 ft) above sea level.[1][2] Development is presumably direct;[1] i.e., there is no free-living larval stage.[6]
This species was quite common at the type locality. Threats to it are unknown. It is not known to occur in any protected area.[1]
