Natural history: The habitat in the distribution area comprises humid mon- tane rainforest and cloud forest. Calling males were observed at night perching on low vegetation in secondary growth as well as in disturbed primary forest apart from any water bodies. During dry conditions, calls were emitted only sporadi- cally, whereas during rain calling activity increased to regular repeated calls like described below. Harvey & Keck (1995) found their specimens during the day under rocks and reported a defensive posture in the obtained female. Vocalization: Advertisement calls were recorded on 25 November 1998 at a point south of Karahuasi, Provincia Carrasco, Departamento Cochabamba, 2150 m Calls consisted of a single pulsed notes with a duration of 91-97 ms (mean ± ) and were repeated in regular intervals at a rate of approximately 22 calls per minute; each note was composed of 11 pulses, repeated at a rate of 120 pulses per second; call energy was distributed from 1400-2200 Hz, with a modu-.
