Detailed advertisement call descriptions are provided for 12 species of hyperoliid frogs <I>(Afrixalus dorsalis, A. osorioi, A. paradorsalis, A. quadrivittatus, Hyperolius cystocandicans, H. glandicolor, H. langi, H. montanus, H. phantasticus, H. puncticulatus, Leptopelis christyi, Phlyctimantis cf. boulengeri)&lt;/I&gt; from different localities in East Africa and Gabon. The call of each species is figured in a spectrogram and waveform. East African populations of frogs of the <I>Afrixalus fulvovittatus&lt;/I&gt; complex are considered to represent <I>A. quadrivittatus&lt;/I&gt; (formerly a junior synonym of <I>A. fulvovittatus</I>). Its advertisement call differs significantly from West African populations reported as <I>A. vittiger</I>. The allocation of green and golden colour morphs from Mount Kenya to the species <I>H. cystocandicans&lt;/I&gt; is confirmed by bioacoustics. The presence of <I>H. kuligae&lt;/I&gt; in East Africa (Uganda) is doubted. Based on morphological comparisons with type specimens, calls of &lt;I&gt;Phlyctimantis&lt;/I&gt; recorded in Gabon are tentatively referred to <I>P.boulengeri</I>. The species is supposed to occur in Cameroon, Equatorial Guinea, Gabon and the Republic of Congo according to advertisement call comparisons. West African populations of &lt;I&gt; Phlyctimantis&lt;/I&gt; may represent an undescribed species.
