Bioacoustics of Hyperolius bangwae

The most common pattern elements in the descriptions of the type of H. bangwae are a dark lateral line (100%), and dark dorsal speckling (100%). An advertisement call from Monts Cristal (ZFMK 73143) consists of a series of brief notes at a mean note rate of 9.5 s- 1 with a mean emphasised frequency of 2271 Hz ( Lötters et al . 2004 , as H. tuberculatus ). A specimen from the same locality was sequenced (AY329321) and identified as H. bangwae . The advertisement call attributed to H. tuberculatus from Binguéla, Cameroon ( Schiøtz 1999 ) is within the range of H. bangwae as here envisaged, and is regarded as a call of H. bangwae . The call consists of a series of brief notes, about 13 s-1 , with an emphasised frequency of 1900 Hz. This is quite different from the call of H. tuberculatus from Río Muni , Equatorial Guinea (no vouchers), as shown by Bosch et al . (2000) . A call from Olemb, Cameroon (as H. tuberculatus ) (no voucher) that consists of a series of simple notes with a note rate of 14 s-1 , and an emphasised frequency of 3000 Hz ( Amiet & Goutte 2017 ) is provisionally regarded as that of H. bangwae , although the call of H. sp. 1 is unknown.
