| checklist and simple identification key for frogs and toads from district iv of the mada scheme, kedah, malaysia. | a survey was conducted to catalogue the diversity of anurans in district iv of the muda agriculture development authority scheme (mada) in kedah darul aman, malaysia, from july 1996 to january 1997. eight species of anurans from three families were present in the study area. of these, the common grass frog (fejevarya limnocharis) was the most abundant, followed by mangrove frog (fejevarya cancrivora), long-legged frog (hylarana macrodactyla), and common toad (duttaphrynus melanostictus). puddle ... | 2009 | 24575178 |
| two new phrynobatrachus species (amphibia: anura: phrynobatrachidae) from the republic of the congo. | we describe two new species of puddle frogs, genus phrynobatrachus, from the south-western republic of the congo. one of them, p. horsti sp. nov., occurs also in neighbouring gabon and is morphologically most similar to the cameroonian p. ruthbeateae. it differs from the latter species by smaller males with longer thighs and shanks. the new species comprises various colour morphs but always has less conspicuous black borders between flanks and belly than p. ruthbeateae. the distinct and large bl ... | 2015 | 26624339 |
| a new puddle frog, genus phrynobatrachus (amphibia: anura: phrynobatrachidae), from the eastern part of the upper guinea biodiversity hotspot, west africa. | we describe a new species of phrynobatrachus from swamp forests in the southern border region of ivory coast and ghana. the new species differs from all other known west african phrynobatrachus by the combination of adult snout-vent-length being between 20 and 30 mm; absence of a spiny tubercle on the eyelid; presence of a dark face mask; a black throat in adult males; narrow and partly indistinct scapular ridges or comma shaped warts; distinct spinulae on males' throats and dorsal surfaces; pro ... | 2018 | 29690454 |
| evolutionary history of the cameroon radiation of puddle frogs (phrynobatrachidae: phrynobatrachus), with descriptions of two critically endangered new species from the northern cameroon volcanic line. | the cameroon volcanic line, a mountain chain located between west and central africa, is a region of numerous endemic diversifications, including of puddle frogs (phrynobatrachus). this study reviews the phylogeny and taxonomy of puddle frogs of the "cameroon radiation," which is a clade containing mainly montane but also at least three lowland species. molecular data revealed a novel evolutionary lineage from high altitudes in the northern part of the mountains. puddle frogs from the new, minut ... | 2020 | 32175182 |
| a new species of puddle frog from an unexplored mountain in southwestern ethiopia (anura, phrynobatrachidae, phrynobatrachus). | a new species of phrynobatrachus is described from the unexplored and isolated bibita mountain, southwestern ethiopia, based on morphological characters and sequences of the mitochondrial rrna16s. the new species can be distinguished from all its congeners by a small size (svl = 16.8 ± 0.1 mm for males, 20.3 ± 0.9 mm for females), a slender body with long legs and elongated fingers and toes, a golden coloration, a completely hidden tympanum, and a marked canthus rostralis. the phylogenetic hypot ... | 2019 | 30799972 |
| a new species of puddle frog, genus phrynobatrachus (amphibia: anura: phrynobatrachidae) from ghana. | we describe a new species of phrynobatrachus from the eastern part of the upper guinea forest region, ghana, west africa. morphologically, the new species can be distinguished from all of its congeners by the combination of a slender body, short and pointed snout, a relatively warty dorsum, a black-spotted throat in both sexes, a gular flap in males, a dark spotted chest, a white-greyish venter with occasional blackish spots, rudimentary pedal webbing, none to slightly dilated finger tips and st ... | 2018 | 29689792 |
| terrestrialization, miniaturization and rates of diversification in african puddle frogs (anura: phrynobatrachidae). | terrestrialization, the evolution of non-aquatic oviposition, and miniaturization, the evolution of tiny adult body size, are recurring trends in amphibian evolution, but the relationships among the traits that characterize these phenomena are not well understood. furthermore, these traits have been identified as possible "key innovations" that are predicted to increase rates of speciation in those lineages in which they evolve. we examine terrestrialization and miniaturization in sub-saharan pu ... | 2012 | 22509392 |
| complex patterns of continental speciation: molecular phylogenetics and biogeography of sub-saharan puddle frogs (phrynobatrachus). | puddle frogs (anura: phrynobatrachidae) are one of the most species-rich sub-saharan amphibian groups, occupying an extraordinarily diverse range of habitats. we construct the first phylogeny of puddle frogs, utilizing mitochondrial (12s rrna, valine-trna, and 16s rrna) and nuclear (rag-1) dna. phylogenetic analyses are conducted using separate and combined partitions under maximum parsimony, maximum likelihood, and bayesian criterion. monophyly of the phrynobatrachidae is well supported, and th ... | 2010 | 20034584 |
