	abstract = {<p>The East African rainforests are areas of prime biogeographical importance. The significance of the amphibian fauna of the region as a biogeographical indicator group, first recognized by Schiotz (1981) is reiterated. Schiotz\&rsquo; 1981 list of East african rainforest amphibians is corrected and updated. A new species of dwarf toad [Nectophrynoides wendyae sp. nov.] from the rainforest of the Uzungwe Mountains, Tanzania is described. The new species is tentatively assigned to the genus Nectophrynoides Noble 1926, and comment on the relationships of the new species and of the Nectophrynoides-Didynamipus group is included. It is suggested that many of the African bufonid genera, especially those including dwarf forms, are currently poorly defined; primitive characters, characters involving the loss of structures and characters subject to a high level of homoplasy often being used. Some possible solutions to this problem are given. The need for a better understanding of the biology of rainforest Amphibia, especially the dwarf species, is seen to be of more immediate importance than the question of their relationships.</p>

	abstract = {<p>The phylogenetic relationships of microhylid frogs are poorly understood. The first molecular phylogeny for continental African microhylids is presented, including representatives of all subfamilies, six of the eight genera, and the enigmatic hemisotid Hemisus. Mitochondrial 12S and 16S rRNA sequence data were analysed using parsimony, likelihood and Bayesian methods. Analyses of the data are consistent with the monophyly of all sampled subfamilies and genera. Hemisus does not nest within either brevicipitines or non-brevicipitines. It is possibly the sister group to brevicipitines, in which case brevicipitines might not be microhylids. Phrynomantis and Hoplophryne potentially group with non-African, non-brevicipitine microhylids, in agreement with recent morphological and molecular data. Within brevicipitines, Breviceps is recovered as the sister group to a clade of Callulina + Spelaeophryne + Probreviceps. The relationships among the genera within this latter clade are unclear, being sensitive to the method of analysis. Optimal trees suggest the Probreviceps macrodactylus subspecies complex might be paraphyletic with respect to P. uluguruensis, corroborating preliminary morphological studies indicating that P. m. rungwensis may be a distinct species. P. m. loveridgei may be paraphyletic with respect to P. m. macrodactylus, though this is not strongly supported. Some biogeographic hypotheses are examined in light of these findings.
