A New Species

We describe and name a new species of Noblella Barbour, 1930 (Strabomantidae) from southern Peru. Key diagnostic characteristics of the new species include the presence of a short, oblique fold-like tubercle on the ventral part of the tarsal region, two phalanges on finger IV, and an evident tympanum. The elevational distribution of the new species spans 1250 m (240–1490 m) from lowland Amazon rainforest to montane forest on the eastern slopes of the Andes.

A New Species

Abstract— Sanchezia dubia is described and illustrated as a new species from the department of Madre de Dios in southeastern Peru. Its morphology slightly resembles Sanchezia sprucei, but its most remarkable feature is its close similarity to Suessenguthia, even more so than to those of its own genus. This new species is distinguished from others by its glabrous stem and leaves, its inflorescence containing two to five serial cymose heads, which are sessile to short-pedunculate, with mostly two to four flowers each (occasionally one), its inner bracts ranging in length between 6 and 23 mm, and its androecium composed of two stamens and two mucronate staminodes. We suggest it is an endangered species based on its restricted geographic distribution, its few known populations, and the increasing threats to its habitats. Along with Suessenguthia koessleri, this new species seems to be a key taxon to understanding the phylogenetic relationship between these two genera, which is still uncertain. Additionally, we provide a key to identify the Sanchezia and Suessenguthia species of the Madre de Dios River basin from southern Peru to northern Bolivia.

A New Species

We describe a new species of Hyalinobatrachium from the Amazonian slopes of the Andes in Peru and Bolivia on the basis of morphological, bioacoustic and genetic characteristics. Hyalinobatrachium carlesvilai sp. nov. can be distinguished from other species of Hyalinobatrachium by the combination of the following characters: (1) truncate snout in dorsal and lateral view; (2) white pericardium; (3) enameled dorsal, tarsal and cloacal folds; (4) hand webbing formula III 2 – – 1 + IV; (5) iris cream; (6) advertisement call consisting of a single, frequency-modulated note with a pulsed section followed by a tonal section. The new species had been previously identified as Hyalinobatrachium munozorum and H. bergeri. The advertisement call of the new species was previously assigned to H. bergeri. Here we describe the previously unknown call of Hyalinobatrachium bergeri. Additionally, we study the taxonomic status of H. lemur and H. pellucidum and place the former as synonym of the later. We extend the distribution of H. pellucidum to Departamento Cusco in southern Peru.

We describe a new species of bromeliad-dwelling Pristimantis from primary montane forest (2,225 m a.s.l.) in southern Peru. The type locality is near Thiuni, in the Department of Puno (province of Carabaya) in the upper watershed of a tributary of the Inambari River. Pristimantis achupalla sp. n. is characterized by a snout-vent length of 10.0–12.8 mm in adult males (n = 4), unknown in adult females, and is compared morphologically and genetically with species in the Pristimantis lacrimosus group, and with other similar species of Pristimantis. The new species is characterized by having skin on dorsum and flanks rugose, green brownish color, distinctive scapular folds, subacuminate or acuminate snout profile, upper eyelid bearing two or three subconical tubercles and some rounded tubercles, rostral papilla, flanks light brown to brown, with irregular dark brown marks.

A New Species

We report the discovery of a geographically disjunct and morphologically distinctive species of direct-developing frog of the genus Phrynopus (Phrynopus mariellaleo sp. nov.) that changes considerably our understanding of the distribution of species in this Andean genus. The type locality lies on a subcordillera (Cerro de Campanario area) of the extreme northeastern portion of the Cordillera Central of Peru, on the headwaters of the Mayo River, Amazonas department, at 2575 m asl (6°6’42.9’’S, 77°26’24’’W). This area is situated 170 km to the NE from the northernmost record of Phrynopus known so far. Molecular phylogenetic analyses of a supermatrix (13269 aligned positions of gene sequences of four mitochondrial and ten nuclear genes) of 105 terminals (representing 93 named and 9 unnamed species of Holoadeninae) recover this new species as the sister to Phrynopus auriculatus, a species occurring more than 500 km south of the type locality of the new species. Both Phrynopus auriculatus and the new species occur at moderate elevations on the easternmost stretches of the Andean subcordilleras; their sister relationship point to a potentially broader distribution of species of Phrynopus along the poorly sampled intervening areas of the eastern hills of the Andes. The new species has a conspicuous and visibly large tympanic membrane (a trait rare in the clade), outlined by a marked bold black supratympanic fold and a black facial mask, and exhibits conspicuous dorsolateral, scapular, and middorsal Y-shaped folds. Specimens were found on the forest floor—a rocky substrate covered by a thick layer of leaf litter, moss and roots—of a primary humid montane forest (Yungas ecoregion) with scattered patches of bamboo (Chusquea spp.). Our phylogenetic analyses corroborate the monophyly of all Holoadeninae genera, including Euparkerella and Psychrophrynella, genera for which tests of monophyly were pending, and corroborates Hypodactylus nigrovittatus as part of Hypodactylus and sister to a clade that includes H. brunneus, H. elassodiscus and H. peraccai.

We describe a new species of minute, terrestrial-breeding frog in the genusNoblella. We collected a single specimen in the leaf litter of primary montane forest (2,225 m a.s.l.) near Thiuni, in the Provice of Carabaya, Department of Puno, in the upper watershed of a tributary of the Inambari River of southern Peru, the same locality where we found the types ofPsychrophrynella glaucaCatenazzi & Ttito 2018. We placed the new species withinNoblellaon the basis of molecular data, minute size, and overall morphological resemblance with the type speciesN. peruvianaand other species ofNoblella, including having three phalanges on finger IV (as inN. coloma,N. heyeri,N. lynchi,N. madreselva,N. peruviana, andN. pygmaea), and terminal phalanges T-shaped and pointed.Noblella thiunisp. n. is distinguished from all other species ofNoblellaby having ventral surfaces of legs bright red, and chest and belly copper reddish with a profusion of silvery spots. The new species further differs from known Peruvian species ofNoblellaby the combination of the following characters: tympanic membrane absent, eyelids lacking tubercles, dorsal skin finely shagreen, tarsal tubercles or folds absent, three phalanges on Finger IV, tips of digits not expanded, no circumferential grooves on digits, inguinal spots present. The new species has a snout–vent length of 11.0 mm in one adult or subadult male. Our new finding confirms the high levels of endemism and beta diversity of small, terrestrial-breeding frogs inhabiting the moss layers and leaf litter in the montane forests of the Amazonian slopes of the Andes and adjacent moist puna grasslands, and suggests much work remains to be done to properly document this diversity.

High Elevations

Two new species of the genus Pristimantis (Pristimantis) that are tentatively placed in the Pristimantis unistrigatus Group are described from the Yanachaga-Chemillén region in Departamento Pasco, Peru, where 24 species of strabomantid frogs are known. Both new species inhabit the humid montane forest on the slopes of the Andean Cordillera Oriental, and one of the new species apparently is a cryptic relative of another inhabitant of the region. Among 60 species of strabomantids recorded in a two-degree wide transect from the Amazonian lowland to the crest of the Cordillera Oriental, only three of the species restricted to mid-elevations are known from transects in northern or southern Peru. High elevations are dominated by terrestrial Phrynopus, whereas the lowlands and forested slopes of the Andes are dominated by arboreal Pristimantis. Within clades there is no elevational correlation with the presence or absence of a tympanum.
