A new glassfrog (Centrolenidae: Hyalinobatrachium ) from the Topo River Basin, Amazonian slopes of the Andes of Ecuador.

摘要

A new species of glassfrog (Centrolenidae) is described from the San Jacinto River, an affluentof the Topo River, on the Amazonian slopes of the Ecuadorian Andes. The new species, Hyalinobatrachiumadespinosai sp. nov., can be differentiated from all other centrolenids by the combination of its coloration(transparent peritoneum and pericardium) and vocalization (call duration = 0.38–0.44 s, with 9–13 pulses percall; dominant frequency = 4,645–5,001 Hz). However, H. adespinosai sp. nov. is morphologically cryptic withH. anachoretus, H. esmeralda, and H. pellucidum, from which it differs by call traits (in H. anachoretus: callduration = 0.32–0.37 s, with 5 or 6 pulses per call, dominant frequency = 4,670–4,800 Hz; in H. esmeralda: callduration = 0.218–0.257 s, tonal call, dominant frequency = 4,739–5,580 Hz; in H. pellucidum: call duration = 0.112–0.140 s, tonal, dominant frequency = 5,000–5,710 Hz). Biogeographically, the new species is separated from H.anachoretus by a considerable distance and, also, the Mara?on valley. Finally, following IUCN conservationcriteria, the status of the new species is considered as Data Deficient.
