Zoology. 96 Frequency (kHz) 10 I 5-. 500 ms t— 1 1 0 250 500 ms : Audiospectrogram and oscillogram of the advertisement call of Hyla andina from Quebrada El Fuerte, 1700 m Recording obtained on 17 November 1994.

Although, it was not possible to record others than the two-note calls described above, calls consisting of more than two notes were heard at La Siberia, Departamento Cochabamba (compare also Marquez et al. 1993). Like previously argued by Reynolds & Foster (1992), the presence of harmonic frequency bands may vary with the material and methods used for recording and analysis. However, differences noted in Bolivian populations to those from northern Argentina, may indicate that their taxonomic status has to be reconsidered. Remarks: During this study the species was found in sympatry with Hyla mar- ianitae and H. cf. caUipleura. two other species in the H. piilchella group. There is remarkable interpopulational variation concerning body size and coloration (see Duellman et al. 1999).
