De la Riva pers. comm.). Natural histor\': Specimens were found in humid montane forests as well as cloud forest habitats. Usually, males called at night from leaves of ferns and bush- es at approximately m height. Calling activity was highest at dusk during light rain. Along the "old" Chapare road few males also called during the day from the forest floor. At da\ time, adults w ere disco\ ered active on the forest floor or in more open habitats under rocks or fallen logs. Juveniles were obser\ ed from No\"ember to February, mostly perching on leaves at night. Vo c a 1 i zat i 0n : Ad\ ertisement calls were recorded on 25 November 1998 south of Karahuasi. Provincia Carrasco. Departamento Cochabamba, 2170 m Calls consisted of short tonal notes: note duration varied from 13-22 ms (mean ± ): notes were repeated in regular inter\ als at a rate of approximately 43 notes per minute: call energy was distributed in a narrow band of about 500 Hz beUveen Eleiitherodactylus rhabdolaemiis Duellman, 1978 Plate Ve. p. 128.
