Based on concordant differences in morphology, male advertisement call, and 16S mtDNA barcode distance, we describe a new species of Proceratophrys from southern Amazonia, in the states of Mato Grosso and Pará, Brazil. The new species is most similar to P. concavitympanum and P. ararype but differs from these species by its proportionally larger eyes and features of the advertisement call. Additionally, genetic distance between the new species and its congeners is 3.0–10.4% based on a fragment of the 16S rRNA gene, which is greater than the threshold typically characterizing distinct species of anurans. Using an integrative approach (molecular, bioacoustics, and adult morphology), we were able to distinguish the new species from other congeneric species. The new species is known only from the type locality where it is threatened by illegal logging and gold mining as well as hydroelectric dams.

A New Species

Based on concordant differences in male advertisement call, tadpole morphology, and absence of haplotype sharing in the barcoding 16S mitochondrial DNA, we describe here a new species of spotted leaf frog of the genusPhasmahylafrom Atlantic Forest, State of Rio de Janeiro, Southeast Brazil. The new species is most similar toP. cochranae(type locality) andP. spectabilis(type locality). It differs from these species by the size of the calcar, moderate-sized body (snout-vent length 30.4–34.4 mm in adult eight males), and in the advertisement call. The tadpoles ofPhasmahyla lisbellasp. nov. differ fromP. exilis,P. spectabilis,P. timbo,P. guttataandP. jandaiabecause they do not have row of teeth in the anterior part; differ fromP. cruziby the shape of the anterior end of the oral disc. Through genetic data (phylogenetic distance and haplotype genealogy) we diagnosed the new species where the genetic divergences among its congeners is about 3–6% in a fragment of the 16S rRNA gene, which is above the threshold typically characterizing distinct species of anurans. However, the new species can be distinguished from other congeneric species based on an integrative approach (molecular, bioacoustics, larval, and adult morphology).

The 16S Rrna Gene

Based on concordant differences in male advertisement call, tadpole morphology, and absence of haplotype sharing in mitochondrial and nuclear DNA markers, we describe a new species of treefrog from Ranomafana National Park in the southern central east of Madagascar. In its adult stage Boophis narinsi sp. n. is highly similar to its sister species, Boophis majori, but appears to differ in having longer hindlimbs. The genetic divergences between these two species (2.5-3.3% in a fragment of the 16S rRNA gene, depending on fragment length and individual haplotype analyzed) are below the threshold typically characterizing distinct species of anurans. Together with their relatively small and largely overlapping ranges and their sympatric occurrence in Ranomafana National Park, this indicates that they potentially could have originated rather recently by adaptive speciation under parapatric or sympatric conditions. Most studies on amphibian speciation have so far by default assumed vicariant speciation. We suggest that alternative speciation scenarios should be considered in future works and characterize settings in which more reliable assessments of adaptive parapatric or sympatric speciation could be carried out.

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 strongly delated toe tips, presence of both inner and outer metatarsal tubercles and absence of a dark face mask, eyelid tubercles and longer dorsal ridges. We collected mitochondrial DNA (mtDNA) sequence data from the 16S rRNA gene to measure the genetic diversity of the new species, and to estimate phylogenetic relationships. The new species is a distinct and monophyletic evolutionary lineage most closely related to Phrynobatrachus gutturosus, P. fraterculus and P. maculiventris. The discovery of this new species highlights that the biodiversity of West African forests is still incompletely known and that the few remaining forests need urgent protection.

A new species of Miconia section Miconia, subsection Seriatiflorae from the Brazilian Amazonian region is described. Miconia renatogoldenbergii has a wide distribution in areas of savanna and forest understory in the states of Pará, Mato Grosso and Rondônia. It is similar to M. punctata as both species have chartaceous leaves with rusty lepidote indument on the abaxial surface. The new species can be distinguished by its mucronate leaf apex, a thyrse with short scorpioid branches, and subulate anthers, with round apex, dehiscent through an apical pore and with cordate connective appendages.

This study describes a new member of the genus Leptobrachella, Leptobrachella shangsiensis sp. nov., based on morphological, acoustic and molecular analyses from southern Guangxi, China. L. shangsiensis sp. nov. differs from its congeners by a combination of the following characters: (1) SVL 24.9–29.4 mm in 11 males and 30.8–35.9 mm in 5 females, (2) black supratympanic fold with dark reddish rim, (3) ventrolateral glands distinct, forming a broken line, (4) ventral surface yellowish creamy-white with marble texture, (5) iris copper in the upper and silver in the lower fifth and (6) toe webbing basal and narrow lateral fringes. The male advertisement call of L. shangsiensis sp. nov. consists of one note per call, lacking an introductory note, with a mean dominant frequency of 5.5–6.5 kHz at the ambient temperature of 21.5ºC. Uncorrected sequence divergences between L. shangsiensis sp. nov. and all homologous DNA sequences available for the 16S rRNA gene were found to be > 5.9%. L. shangsiensis sp. nov. occurs in an evergreen forest in Shiwandashan National Nature Reserve located at an elevation of 450–550 m.

In this article, a new species of salamander of the genus Bolitoglossa (Eladinea) from the cloud forest near La Mucuy in Sierra Nevada de Mérida, Venezuelan Andes, is described. Bolitoglossa mucuyensis sp. nov. differs from all Venezuelan salamanders, except B. orestes, by a larger SVL/TL ratio, and from La Culata salamander B. orestes by a reduced webbing extension of the front and hind limbs. Additionally, B. mucuyensis sp. nov. and B. orestes diverge 3.12% in terms of the nucleotide sequence of the 16S rRNA gene, as previously reported, and in 8.1% for the cytb gene as shown in this study.

A New Species

The genus Caliciopsis (Eurotiomycetes, Coryneliales) includes saprobic and plant pathogenic species. Caliciopsis canker is caused by Caliciopsis pinea Peck, a species first reported in the 19th century in North America. In recent years, increasing numbers of outbreaks of Caliciopsis canker have been reported on different Pinus spp. in the eastern USA. In Europe, the disease has only occasionally been reported causing cankers, mostly on Pinus radiata in stressed plantations. The aim of this study was to clarify the taxonomy of Caliciopsis specimens collected from infected Pinus spp. in Europe and North America using an integrative approach, combining morphology and phylogenetic analyses of three loci. The pathogenicity of the fungus was also considered. Two distinct groups were evident, based on morphology and multilocus phylogenetic analyses. These represent the known pathogen Caliciopsis pinea that occurs in North America and a morphologically similar, but phylogenetically distinct, species described here as Caliciopsis moriondisp. nov., found in Europe and at least one location in eastern North America. Caliciopsis moriondi differs from C. pinea in various morphological features including the length of the ascomata, as well as their distribution on the stromata.

A New Species

Within Sundaland, the species diversity of the genus Megophrys is richest in Borneo, with some species restricted to the northern highlands of the island. On the basis of molecular, morphological and acoustic evidence, we describe a new species of large-sized Megophrys, once confused with M. nasuta. The new species Megophrys kalimantanensis sp. nov. can be differentiated from all its congeners by large genetic distance more than 6.11% in the mitochondrial 16S rRNA gene, much shorter rostral and orbital appendages, and unique advertisement call. This new species has been recorded from medium to high altitudes of mountain forest in southern and northernmost Borneo.
