Bioacoustics of Hyperolius glandicolor

This clade occurs in Rwanda , Uganda , northern Tanzania and southern Kenya ( Fig. 8B ). The clade distribution closely matches the distribution of types that are regarded as junior synonyms, and sequences occur at the type locality. The localities of the type and taxa now regarded as junior synonyms of H. glandicolor are listed in Table 3 . The most common pattern element in the descriptions of the types included in H. glandicolor is dorsal marbling (39%), followed by speckle or small spots that may be black or blue (33%). The percentages are not additive, as the pattern elements may be shared. An advertisement call from Kakoneni, Kenya (no voucher) shows individual notes with a length of about 0.1 s , and an emphasised frequency of 2800–3150 Hz ( Schiøtz 1975 , 1999 , as H. sheldricki ). A call from Arusha National Park in Tanzania (no voucher) shows brief whistles with frequency modulation, with a mean emphasised frequency of 2200 Hz ( Schiøtz 1975 ). This is similar to calls from Kisessa, Tanzania (no vouchers), as H. goetzei ; Arusha , Tanzania , as H. ommatostictus and Lake Naivasha, Kenya , as H. ferniquei ; Nyahuru, Kenya , as H. pantherinus ( Pickersgill, 2007 ) . An advertisement call consisting of a brief note with an emphasised frequency of 1950 Hz was recorded at Lake Bunyoni, Uganda (no voucher), as H. v. pitmani and at Kabale , Uganda (no voucher) as H. pitmani ( Pickersgill 2007 ) . This is similar to calls from Mwanza (no vouchers) in Tanzania that have an emphasised frequency of 2800 Hz ( Schiøtz 1975 , 1999 , Pickersgill 2007 , as H. mwanzae ) and Kisiizi, Uganda (no vouchers) ( Pickersgill 2007 , as H. variabilis ).
