A New Species

A new species of Physalaemus from Misiones province, Argentina, in the Atlantic forest domain is described. The new species is a member of the P. gracilis group, based on its phylogenetic position and the occurrence of a putative morphological synapomorphy (occurrence of an unpigmented median stripe on throat, chest, and/or abdomen). Physalaemus sp. nov. is characterized by a long advertisement call composed of non-pulsed notes with slightly descendant modulation, large size (mean SVL = 32.0 mm males, 34.0 mm females), slender body aspect, head longer than wide, supratympanic fold developed, an unpigmented median stripe on venter, medium sized inguinal glands, tarsal tubercle present, and supernumerary tubercles on hands and feet, which are character states that combined distinguish the new species from all the members of the genus. In this study, we provide its formal description based on external morphology, advertisement call, and 16S genetic distance. In addition, the distribution ranges for the new species and P. gracilis are revisited, the advertisement call of P. gracilis is redescribed, and a discussion about the available names which could be applicable to the new species is provided.

A New Species

A new species of Leptodactylus belonging to the L. fuscus species group, and related to the L. mystaceus complex, is described from the Lagoa das Bromélias (20 o 53’S, 42 o 31’W; 1,227 m above sea level), Parque Estadual da Serra do Brigadeiro, Municipality of Ervália, State of Minas Gerais, Southeastern Brazil. Leptodactylus cupreus sp. nov. is characterized by the large size for the group (SVL 50.1–55.1 mm in males) and color pattern. The new species has a non-pulsed advertisement call, with call rate about 12 calls/s and a dominant frequency between 2,800 and 3,058 Hz.

A New Species

A new species of Paratelmatobius is described from the Brazilian Atlantic Forest in the state of Paraná in southern Brazil. Adults, tadpoles, and vocalizations are described. Morphological traits and phylogenetic analysis place the new species within the P. cardosoi group. The new species can be readily distinguished from its congeners by its advertisement call being composed of two note types and comprised of a series of 2–4 notes. The new species is classified as an explosive breeder, having reproductive activity strongly associated with heavy rainfall. This discovery highlights the importance of intensifying survey efforts in the Atlantic Forest, a domain with high levels of species richness and endemism.

A New Species

Brachycephalus is a frog genus endemic to the Brazilian Atlantic Forest and characterized by the bright yellow-orange aposematic colors and the high degree of miniaturization. Herein, we describe a new species of Brachycephalus from Serra do Brigadeiro, Municipality of Ervália, Minas Gerais State, southeastern Brazil. Specimens were collected at high altitudes (i.e., 1266–1498 m above sea level) amidst the leaf litter. The new species is characterized by the presence of black connective tissue covering all dorsal muscles, body completely yellow-orange in life, presence of skull and post-cranial plates, large size (SVL of adults: 14.8–18.5 mm), bufoniform body, absence of metacarpal and metatarsal tubercles, and presence of harmonics in its advertisement call.

A New Species

A new species of Hyloscirtus, belonging to the H. bogotensis species Group, is described from the Venezuelan and Colombian slopes of the Sierra de Perijá. The new species can be readily distinguished from its congeners by the combination of the following characters: mental gland present, disc-shaped and small; ulnar, outer, and inner tarsal folds present; calcar tubercle absent; whitish stripes on external border of upper eyelids and supratympanic folds, longitudinally on the mid-dorsum, on supracloacal fold, outer ulnar folds, inner and outer tarsal folds, and also on dorsal internal surface of shanks. We estimate phylogenetic relationships based on mtDNA (spanning fragments of 12S rRNA, tRNA-Val and 16S rRNA), of all Hyloscirtus species available in Genbank, as well as the new species described herein, H. callipeza, H. jahni, and H. platydactylus, all of which have not been previously sequenced. Our molecular data support the hypothesis of the new species as sister species of H. callipeza and indicates that H. jahni does not belong to the H. bogotensis species Group, but rather is sister species of all other Hyloscirtus (sensu Faivovich et al. 2005). Based on this last result we propose a new species group for H. jahni and the synonymy of Colomascirtus in Hyloscirtus. We also provide the first description of the advertisement call of H. callipeza. With the new species described herein, the number of Hyloscirtus species increases to 37.

A New Species

With 566 species, the neotropical genus Pristimantis is the most speciose vertebrate genus. As a result of its striking diversity, taxonomic reviews remain a challenge. Herein, we present an updated phylogeny of the Pristimantis lacrimosus group and describe a new species from Llanganates and Sangay National Parks. We also report, for the first time, the phylogenetic position of Pristimantis degener, P. eugeniae, P. katoptroides, and P. petersi. Based on our phylogeny, we add two species to the Pristimantis lacrimosus group. Through the integration of molecular and bioacoustic evidence, we describe a new species which was hidden under “Pristimantis petersi”. Pristimantis petersioidessp. nov. is most closely related to Pristimantis petersi and an undescribed species from Peru. It can be distinguished from P. petersi by its advertisement call and large genetic differences (uncorrected p-genetic distances 7.9% to 8.4% for gene 16S). Moreover, the new species and P. petersi are not sister species. We suggest assigning the new species to the Endangered Red List category because it has a small distribution range with deforestation as result of agriculture and other anthropogenic influences.

A New Species

A new species of large green treefrog of the genus Litoria is described from the Mamberamo Basin of western New Guinea. It can be distinguished from all congeners by a suite of characteristics including moderately large size (male SVL 56–68 mm), moderate finger webbing, labial stripe absent or very indistinct, and lateral body surfaces and webbing with distinctive light purple colouration. Morphologically, the new species is most similar to Litoria sanguinolenta and, to a lesser extent, L. infrafrenata. However, the advertisement call, a very long series of monotonously repeated, distinctly pulsed notes, differs from the calls of these two species.

A new species from the Brazilian Atlantic Forest, Uleiorchis prataënsis, is described, with illustrations and scanning electron micrographs of pollinaria and seeds. Comments on the new species are presented with a key to the species of the genus. Because the phylogenetic position of Uleiorchis has not been previously evaluated with DNA data, we estimated phylogenetic relationships using nrITS sequence data to confirm that this genus is a member of Gastrodieae. The results indicate with high support in both maximum parsimony and maximum-likelihood analyses that both species of Uleiorchis are sister and members of this tribe. Finding a new species in a relatively well-collected place such as Paraná State supports the status of high diversity hotspot for the Atlantic Forest and demonstrates the need for more fieldwork on orchids and other families.
