Short communications: Calls of three species of arthroleptid frogs from Río Muni, Equatorial Guinea
The calls of three anuran species in the family Arthroleptidae in the sub-family Astylosterminae from Equatorial Guinea are described including information on calling behaviour. For each species, we present a characteristic audiospectrogram and oscillogram. We also provide numerical information about the spectral and temporal features of the calls. The calls are compared with previously published descriptions from other parts of their distribution. A new call type is described for Leptodactylodon
Key words: Amphibia, Arthroleptidae, audiospectrograms.
