Gastrotheca sp.

Remarks.

The marsupial frogs of the genus Gastrotheca were recorded by audio records, but were difficult to capture, in the cliffs and southern montane forests of the Naturetrek-Vizcaya Reserve at 2270 m elevation. The auditory records analysed are similar to those issued by Gastrotheca riobambae (Fowler, 1913) which has been recorded a few kilometres from Naturetrek-Vizacaya Reserve in the locality of El Triunfo (Ortiz and Morales 2000), confirming the record would broaden the distribution range of the species. G. testudinea ( Jiménez de la Espada, 1871) has been recorded near this locality in agriculture and forest lands, so there is a possibility that both species are present in the area.
