Air temperature °C. Vo c a 1 i z a t i o n : Advertisement calls were recorded on 17 January 1998 approx- imately 29 km southeast of Guadalupe, Provincia Vallegrande, Departamento Santa Cruz, 1650 m The call consisted of a single frequency modulated note with a duration of 67-87 ms (mean ± ); notes were repeated at regular intervals at a rate of 89-182 notes per minute (mean ± ); call energy was distributed between 830 and 2320 Hz, with a dominant frequency peak at 1970 Hz; calls were indistinctly pulsed and lacked harmonic structures. Twenty-three calls of one individual analyzed; air temperature was °C during recording. These data differ only slightly from calls of L. gracilis from Buenos Aires, Argentina (Barrio 1965b, 1973, Heyer 1978), with respect to a slightly longer note duration and little bit lower note repetition rate (Köhler & Lötters 1999c). Leptodactylus griseigiilaris (Henle, 1981) Plate Vic, p. 144 Distribution: The species was previously known from the eastern slopes of the Andes from central Peru southward to the Yungas de La Paz region, Bolivia, inhabiting elevations of 100-1800 m (Heyer 1994). During this study, L. gri- seigidaris was collected in Provincia Chapare, Departamento Cochabamba, Bolivia, which represents the southern and easternmost record for the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Bonn, Zoologisches Forschungsinstitut und Museum Alexander Koenig
