A New Species of Torrent-Dwelling Frog (Hylidae, Litoria) from the Mountains of New Guinea

Abstract

Litoria megalops sp. nov. from mountain torrents in Papua Province, Indonesia is described. It is most similar to L. micromembrana from which it is distinguished by its smaller size (male SVL: 24.6–27.5 vs 31.7–35.5 mm), exceptionally large and prominent eyes, and conical tubercles on the dorsum. The advertisement call of the new species is a short pulse train with 7–10 pulses per call and lasting 0.9–1.3 s. The new species was found at night on low vegetation along torrents in closed-canopy lower montane rainforest.
