	abstract = {<p>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.</p>

It is similar morphologically to Cacosternum boettgeri from the interior of southern Africa, and is distinguished on the basis of an advertisement call with double or treble pulsed notes. Skeletal and DNA sequence differences support the species status of this taxon. It is known from northern Tanzania and the highlands of Kenya.},

	abstract = {We describe a new frog species of the genus Cardioglosso from the Upper Guinean forests of West Africa. Cardioglosso occidentalis, new species, is found in primary rainforests in Ghana, Ivory Coast, Guinea, Liberia, and Sierra Leone. We demonstrate that this species is morphologically and genetically distinct from C. leucomystax, the species to which these populations were previously assigned. Cardioglossa occidentalis differs from similar congeners by the following combination of markings: fusion or near fusion of all three dorsal lobes (cephalic, scapular, and lumbar); prominent white line extending anteriorly from arm terminates ventral to eye; dark mask extending posteriorly from eye continues unbroken beyond posterior border of scapular lobe; lateral body covered in very few, large dark spots rimmed with thin white. Cordioglosso occidentalis appears related to C. leucomystax, C. melanoguster, and C. schioetzi. This description brings the number of Cardioglossa species to 16.},
