From Amazonia to the Atlantic forest: molecular phylogeny of Phyzelaphryninae frogs reveals unexpected diversity and a striking biogeographic pattern emphasizing conservation challenges.
High Levels of Diversity Uncovered in a Widespread Nominal Taxon: Continental Phylogeography of the Neotropical Tree Frog Dendropsophus minutus
The results, at a spatial scale and resolution unprecedented for a Neotropical vertebrate, confirm that widespread amphibian species occur in lowland South America, yet at the same time a large proportion of cryptic diversity still remains to be discovered.
A new Dendropsophus Fitzinger, 1843 (Anura: Hylidae) of the parviceps group from the lowlands of the Guiana Shield.
A minute tree frog from the Guiana Shield originally assigned to the allegedly widely distributed Dendropsophus brevifrons proved to be a yet undescribed species within the D. parviceps group is described and a phylogeny for the group is presented.
Phylogenetic position of Dendropsophus gaucheri (Lescure and Marty 2000) highlights the need for an in-depth investigation of the phylogenetic relationships of Dendropsophus (Anura: Hylidae)
The genetic distances among D. gaucheri samples studied are low confirming their conspecificity and suggesting recent connections among populations from open areas currently isolated by rainforest in the lowlands of the Guiana Shield.
Chromosome Evolution in Dendropsophini (Amphibia, Anura, Hylinae)
The authors' results reveal significant karyotype diversity among Dendropsophini, with diploid chromosome numbers ranging from 2n = 22 in S. goinorum, 2n= 24 in Lysapsus, Scinax, Xenohyla, and almost all species of Sphaenorhynchus and Pseudis, and adiploid number reduction from 24 to 22 in Scarthyla by a chromosome fusion event.
Description and phylogenetic relationships of a new species of treefrog of the Dendropsophus leucophyllatus group (Anura: Hylidae) from the Amazon basin of Colombia and with an exceptional color…
Morphological traits, such as the presence of pectoral glands in males and females, support the hypothesis that the new species is a member of the D. leucophyllatus species group and sister to D. bifurcus.
A cladistic analysis of the Stygnicranainae Roewer, 1913 (Arachnida, Opiliones, Cranaidae) – where do longipalp cranaids belong?
A character survey compiling the morphological information of the subfamily Stygnicranainae was carried out, finding a monophyletic Stygni Branainae including Tryferos Roewer, 1931 plus Stygnicsranaus and Agathocranaus including only the genus Heterocranainae, 1913.
Integrative taxonomy supports the existence of two distinct species within Hypsiboas crepitans (Anura: Hylidae)
It is suggested that the populations from the two geographical ranges are not conspecific, and Hypsiboas xerophyllus (Duméril & Bibron, 1841) is resurrected for the populations of the northwestern group.
A new "Bat-Voiced" species of Dendropsophus Fitzinger, 1843 (Anura, Hylidae) from the Amazon Basin, Brazil.
A new species of treefrog diagnosed by the presence of pointed fingers and an advertisement call with a very high dominant frequency is described, tentatively included in the Dendropsophus microcephalus Group.
A new species of the Dendropsophus parviceps group from the western Amazon Basin (Amphibia: Anura: Hylidae)
The new species is most closely related to D. parviceps, D. brevifrons, and D. koechlini, and it can be readily distinguished from these and all other members of the D.Parviceps group by, among other characters, its plain dorsal light brown coloration, copper iris, plain immaculate pale yellow to white venter coloration and lack of flash marks on groin and axillae.
