The sharp-nosed reed frog is widespread in Africa. Although currently recognized as one species, suggestions have been made that more than one species might exist. We analysed 237 calls of 69 males from 19 localities in the western to southern parts of Africa. Calls fall into three groups, which we recognize as cryptic species. Of eight published sound spectrograms, all can be assigned to one of the three species. We recognize Hyperolius nasutus, distributed from western Africa to the Okavango Delta in Botswana; Hyperolius viridis, from the central highlands of northwestern Zambia to southern Tanzania; and Hyperolius acuticeps which occurs from the Ivory Coast to the southeastern coast of South Africa. We assign published names to the synonymies of these three species. No call data are available for populations in the Congo basin.

A new species of puddle frog in the genus Phrynobatrachus (Ranidae) is described from central Tanzania. It is compared to all other East African species and found to be most similar to P natalensis. The distinctive features of this species include the male advertisement call, visible tympanum, snout-vent length, and the lack of digital discs.

It is bordered by the Kilombero flood plain to the west and forms a continuous mountain block with the Mbarika to the south, lying close to the Udzungwa and Southern Highland Mountain blocks. The amphibian fauna of the forests of Mahenge Mountain has not been investigated until recent fieldwork carried out in the Sali Forest Reserve that has revealed a diverse forest fauna. In this study new records are reported, details of habitats are given and a checklist of the amphibians and reptiles of Mahenge Mountain are provided. In addition, biogeographical analyses were carried out to investigate patterns of spatial turnover in species. This was achieved by calculating the standard similarity index between the amphibian assemblages of the highland Mahenge Mountains (>850 m) and the lowland Kilombero floodplain (<400 m). The results show significant differences (62\%) between the two areas, reflecting large altitudinal turnover in species between the widespread lowland fauna and the montane fauna. This is further emphasized by a comparison of transects in lowland Mozambique and highland Zimbabwe, which has a comparable similarity index measure of 54\%, impressive when comparing the difference in distance and altitude between the two transects. The reasons for this marked lowland-highland differentiation in Tanzania are poorly understood. Concern is raised for the preservation of this highland endemic fauna in the light of continuing habitat destruction.}, author = {Loader, Simon P. and Poynton, J.C. and Mariaux, Jean} } @article {227, title = {Contribution to the taxonomy of hyperoliid frogs (Amphibia: Anura: Hyperoliidae): advertisement calls of twelve species from East and Central Africa}, journal = {African Zoology}, volume = {40}, number = {1}, year = {2005}, month = {Apr 05}, pages = {127-142}, abstract = {

Detailed advertisement call descriptions are provided for 12 species of hyperoliid frogs (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) 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 Afrixalus fulvovittatus complex are considered to represent A. quadrivittatus (formerly a junior synonym of A. fulvovittatus). Its advertisement call differs significantly from West African populations reported as A. vittiger. The allocation of green and golden colour morphs from Mount Kenya to the species H. cystocandicans is confirmed by bioacoustics. The presence of H. kuligae in East Africa (Uganda) is doubted. Based on morphological comparisons with type specimens, calls of Phlyctimantis recorded in Gabon are tentatively referred to R boulengeri. 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 Phlyctimantis may represent an undescribed species.
