	abstract = {A new ranid frog is described from the mountains of the southwestern Cape Province, South Africa. It is placed in the Petropedetinae, but cannot be assigned to any existing genus. We erect the genus POYNTONIA to accommodate it and name the new frog Poyntonia paludicola. Poyntonia may be separated from the other genera of petropedetine ranids by the absence of a tympanum, the lack of digital discs, a tarsal tubercle, and lingual papilla, and the presence of webbing and an ossified omosternum. Populations of Poyntonia paludicola are known from five localities, all marshy habitats at high elevations in the southwestern Cape mountains. Adults are of moderate size (SVL 30 mm) and are very warty. The tadpoles are distinguishable from other ranid tadpoles by their small mouth, long tail, and presence of minute sharp tubercles in areas corresponding to positions of adult warts. The diploid chromosome number is 2N = 24. A sonagram of the male advertisement call is presented.},

	abstract = {<p>A new genus and species, ERICABATRACHUS baleensis, is described from forested localities in the Bale Mountains of Ethiopia. The new taxon seems most closely allied to Petropedetes Reichenow 1874, from West Africa, and to Arthroleptides Nieden 1910, which is found in Kenya and Tanzania. It resembles these genera in being associated with fast-flowing forest streams and there is circumstantial evidence of a terrestrial life cycle, perhaps similar to that observed in some species of Petropedetes. Morphological features which are considered to justify the recognition of a new genus include the small size and distinctive habitus of the animal, significantly reduced first finger and subarticular tubercles, and a striking ventral colour pattern.</p>
