A New Species

We describe a new species of Rhinella from montane forests between 1788 and 2305 m a.s.l. in the Departamentos Amazonas and San Martín, Peru. We tentatively assign the new species to the Rhinella festae species Group based on morphological similarities with its other 19 members. It is characterised by large size (maximum SVL 91.6 mm in females), a pointed and protruding snout that is posteroventrally inclined, absence of a visible tympanic annulus and tympanic membrane, long parotoid glands in contact with upper eyelid, presence of a dorsolateral row of enlarged tubercles, outer dorsolateral tarsus surface with a subconical ridge of fused tubercles, and absence of subgular vocal sac and vocal slits in males. One specimen from Departamento Amazonas tested positive for Batrachochytrium dendrobatidis.

A New Species

We describe a new species of Pristimantis from southern Ecuador, province of Zamora Chinchipe. The new species is closely related to an undescribed species of Pristimantis from Reserva Tapichalaca, Ecuador and with species of a clade historically assigned to the P. unistrigatus species group, such as P. parvillus, P. luteolateralis, P. walkeri, among others. The new species of Pristimantis is a miniaturized new frog (females 17.1±1.1 mm; males 13.2±0.9 mm), characterized by the presence of “› ‹”-shaped scapular folds, with two subconical tubercles on the medial and posterior regions of folds; tympanic membrane and tympanic annulus present but not externally visible; a prominent rostral papilla present; upper eyelid with one elongated conical tubercle; a conical tubercle on heels; groin with orange or yellow spots. The new species of Pristimantis is distributed in a restricted area in the Cordillera del Condor, a highly-diverse mountain range threatened by multiple anthropogenic activities. We recommend assigning the new species to the Endangered IUCN threatened category because it is only known from three nearby localities within mining concessions.

A New Species

We describe a new species of Cyrtodactylus from lower montane forests on the Torricelli and Foja Mountain ranges of northern New Guinea. Cyrtodactylus boreoclivus sp. nov. can be distinguished from all other described Cyrtodactylus by the combination of moderately large size (SVL 104–109 mm), males with pores extending to the knee and arranged in independent precloacal and femoral series, transversely enlarged subcaudal scales, and dorsal pattern consisting of five to seven indistinct transverse dark bands. The known distribution of this species is similar to many other vertebrate taxa apparently restricted to isolated ranges within the North Papuan Mountains, and supports the biogeographic association of these poorly known upland areas.

A New Species

Pristimantis is the most diverse genus of tetrapods comprising 532 described species. It contains a large number of morphologically cryptic species that are being discovered with the assistance of genetic evidence. We use molecular, morphological, bioacoustic, and environmental data to assess the phylogenetic relationships and determine the species within an Andean clade of Pristimantis, which is distributed from central Ecuador to northern Peru. We assign to this clade the name Huicundomantis and propose it as a subgenus. Our results show that Huicundomantis is composed of two large clades which we name as the P.phoxocephalus species group and the P.cryptomelas species group. Huicundomantis is composed of 28 species of which 12 have been described and 16 are new. We describe 11 of these undescribed species. The most effective characters to discriminate among species are DNA sequences, qualitative morphology, and advertisement calls. Morphometric and environmental characters are not very useful to define species limits. We clarify the identity of P.riveti and show that populations from southern Ecuador traditionally ascribed to P.riveti are a new species, P.lutzaesp. nov. We also show that P.prometeii is a junior synonym of P.hampatusami. The current diversity and geographic distribution of Huicundomantis are consistent with a model of allopatric speciation. All species have a restricted distribution range (less than 4330 km2) and are assigned to the Red List categories Data Deficient or threatened with extinction. We provide new reasons to increase conservation efforts for these species and their habitat. Taking our results into account, Pristimantis species richness in Ecuador increases from 211 to 221 species, and the number of species endemic to Ecuador from 119 to 129.

A New Species

We describe a new species of marsupial frog, genus Gastrotheca, using morphological characters and molecular data as lines of evidence. The new species was discovered in the páramo and the ecotone between páramo and humid montane forest of Cordillera de Colán, at elevations between 3136 and 3179 m a.s.l., in northeastern Peru. The new species is distinguished from all its congeners by the combination of the following characters: coarsely granular skin on dorsum, a green dorsal coloration without pattern, finger I shorter than finger II, turquoise iris, and a venter without blotches, flecks or dots. Furthermore, we include a detailed osteological description of the new Gastrotheca species based on Micro-CT scanning. Based on our phylogenetic analyses, the new species belongs to the Gastrotheca marsupiata species group, is sister to G. oresbios and closely related to G. psychrophila, G. spectabilis, G. stictopleura and one undescribed species. Additionally, we test for the presence of the fungal pathogen Batrachochytrium dendrobatidis (Bd). No Bd infection was detected for G. gemma sp. nov. specimens but Bd prevalence was detected among syntopic frogs.

A New Species

We describe a new species of Anolis from the western slopes of the Andes in Ecuador, Provincias Cotopaxi and Pichincha. The new species fits into (1) the aequatorialis species group by being of moderate to large size with narrow toe lamellae and (2) the eulaemus subgroup by having a typical Anolis digit, in which the distal lamellae of phalanx II distinctly overlap the proximal scales of phalanx I. The new species is most similar to A. gemmosus O’Shaughnessy but differs from it by features like the presence of a dark coppery brown stripe on the sides of the head (stripe absent in A. gemmosus), females with dark brown dorsal chevrons extending to the flanks (chevrons absent in A. gemmosus), male dewlap white with green scales (male dewlap greenish-yellow with green scales in A. gemmosus), dewlap with wide scale rows of three to six scales per row (narrow scale rows of 2−3 scales per row in A. gemmosus), and interparietal scale (if present) surrounded by relatively enlarged flat scales (interparietal surrounded by small swollen scales in A. gemmosus). These two species occur in sympatry in the Reserva de Bosque Integral Otonga, Provincia Cotopaxi, Ecuador.

A New Species

We describe a new species of the cricetid rodent Thomasomys (Sigmodontinae) of the "aureus" group based on four specimens collected from Carmen de la Frontera, Piura Department, Peru. This new species has a very long and white tail, very long mystacial vibrissae that extend posteriorly beyond the pinnae, and a distinctive cranial and dental morphology that differ from any other known species of Thomasomys. It is also one of the largest species of Thomasomys, exceeded in size only by T. apeco. A phylogenetic analysis using sequences of Cytb recovered this species within a non-monophyletic "aureus" group with a genetic distance between 5.47% (with T. auricularis) to 10.17% (with Thomasomys sp. 1). In addition to this finding, the phylogenetic position of T. apeco, T. praetor, and T. pyrrhonotus are presented for the first time, prompting a discussion on the nature of the "aureus" group.

A New Species

We describe a new species of Pristimantis from cloud forests of the eastern versant of the Andes in northern Peru. Thetype locality lies in Quebrada del Vino, Provincia San Ignacio, Departamento Cajamarca, Peru. The new species is mostsimilar to P. crucifer, P. eriphus, P. flavobracatus, P. leucorrhinus, P. lucasi, and P. vilcabambae, with which it shares thepresence of large conical eyelid tubercles, ulnar tubercles, and heel and tarsal tubercles as well as flash colours on the groinsurrounded by bold black stripes and white stripes. The new species can nonetheless be distinguished from all of them by,having tympanic membrane and annulus, by males having nuptial pads and vocal slits, and by having finger discs scarcely enlarged and truncated with ungual flap not indented.
