One New Species

Two new species of Gastrotheca are represented by adult females, genomic data of these are included in a phylogenetic analysis, whereby they are placed in the northern clade of the subgenus Gastrotheca. One new species, G. spectabilis, is unique within the genus in having a color pattern consisting of white labial, rostral, and canthal stripes. The second new species, G. oresbios, has a dorsal color pattern of dark paravertebral markings and canthal stripe, but no pale labial stripe; thus it resembles G. abdita, which differs by having an inner tarsal fold, a wider interorbital distance, and smooth skin on the dorsum lacking scattered tubercles as in G. oresbios. Of the nine species of Gastrotheca in the northern Cordillera Central, only G. spectabilis, G. ossilaginis, and G. oresbios lack an inner tarsal fold. The third species is represented by two juveniles; it is briefly described but not named. Of the nine species of Gastrotheca known from the high elevations in the northern part of the Cordillera Central in northern Peru, only two are members of the subgenus Duellmania that occurs principally north of the Huancabamba Depression. Only one of the nine species of species of Gastrotheca in the northern part of the Cordillera Central is shared with the Cordillera Occidental in Peru, and none of the species is shared with the Ecuadorian ranges of the Andes

Discriminant Function Analyses

The Gonatodes concinnatus complex, as here considered, consists of Gonatodes species characterized by a white suprahumeral spot with black margins; vermiculations or not on back; and transversely enlarged scales under the tail, showing the sequence 1’1’1”, and in some specimens 1’1’2” on the anterior portion. Two species are presently recognized in this Amazonian complex: G. concinnatus and G. tapajonicus. New material collected in eastern Amazonia (states of Pará and Amapá, Brazil) made it necessary to review these species. We analyzed several populations within this complex, from Colombia, Ecuador, Peru, Venezuela and Brazil, including these new records. Specimens were separated in groups defined on basis of color pattern. Stepwise discriminant function analyses were then performed to compare the external morphology (measurements and scale counts) in these groups. Results support recognition of five taxa, corresponding to G. concinnatus from western Amazonia, in Ecuador and northern Peru; G. ligiae from northwestern Venezuela (east of the Andes); G. tapajonicus, from the Tapajós river basin, in Pará, Brazil; and two new species, one from eastern Amazonia, in the states of Pará (north and south of the Amazon river) and Amapá, Brazil, and another from central Colombia, east of the Andes. Diagnoses and descriptions of all species are presented.

Two new species of Cnemidophorus are described from the right bank of the São Francisco river, in the northwestern part of state of Bahia, Brazil. Both species are assigned to the Cnemidophorus ocellifer group and are distinguished from all other congeners on the basis of lepidosis and color pattern. One of them, Cnemidophorus cyanurus, shares with the species of the subgroup of C. littoralis (C. abaetensis, C. littoralis and C. venetacaudus), a bluish green tail, spurs on the heels of males, 6–7 supraciliaries, a high number of femoral pores (27–45), a row of enlarged scales in the dorsal part of the humerus, and 8 to 10 rows of ventral scales. The second species, Cnemidophorus nigrigula, shares with the C. ocellifer subgroup (composed of C. ocellifer, C. mumbuca, C. jalapensis and C. confusionibus) a low number of femoral pores (14– 21), enlarged scales in the temporal region posterior to the third subocular, 5 supraciliaries, 6 to 8 rows of ventral scales, and a brown tail color. It is also characterized by males being conspicuously larger than females and by females retaining the juvenile color pattern, which is lost in adult males. The latter characteristic has not been reported in any species of the C. ocellifer group before now. The two new species occur sympatrically at Santo Inácio.

One New Species

We studied populations of frogs of the genus Atelopus from the Pasto Massif of the Andes in southern Colombia and northern Ecuador, and from the Huancabamba depression in southern Ecuador and northern Perú and conclude that they belong to six species, five of which are described as new to science. Atelopus angelito is recorded for the first time from Ecuador and its range is extended 183 km (airline) southwest of its type locality in Departamento del Cauca, Colombia. We distinguish the five new species from similar ones using features of coloration, skin texture, and morphometrics. We also include osteological data for four of the new species. A putative hybrid zone at Provincia Imbabura, Ecuador, is proposed to exist between the non-sister taxa A. ignescens and one of the new species. Because recent records of four of the new species and A. angelito are lacking despite search efforts, we hypothesize that they are possibly extinct, as are many other Andean Atelopus. Thus, we categorize these species, applying IUCN Red List criteria, as Critically Endangered (Possibly Extinct). No search efforts have been carried out for one new species (from La Victoria, Colombia); thus, it is included under the Data Deficient category. The conservation of Atelopus is briefly discussed.

We describe two new species of terrestrial-breeding frogs in the genus Pristimantis from the Andes of northeastern Peru, Amazonas Department. Both species share several characters with other congeners from northern Peru, such as the presence of prominent conical tubercles on their eyelids and heel, prominent conical tubercles along the outer edge of the tarsus, and discs on fingers and toes widely expanded. However, both species can be diagnosed from morphologically similar Pristimantis in the region. Pristimantis kiruhampatu has axillae, groins, and hidden surfaces of hindlimbs that are cherry with white minute flecks, tympanic membrane and tympanic annulus evident, conical tubercles along the edge of snout and outer edge of tibia, and \/ shaped folds in the scapular region. Pristimantis paulpittmani has yellow or dirty cream groins and hidden surfaces of hindlimbs, whitish cream irises with scattered dark brown reticulations, and a thin vertical dark brown streak at the middle of the eye, snout subacuminate with a conical tubercle at the tip, and lacks a tympanic annulus and membrane. Additionally, we provide a short description of the advertisement call of P. kiruhampatu.

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.

A New Species

A new, and only the third known species of the Neotropical montane genus Oressinoma Doubleday is described—O. sorina n. sp., from the Andes of central Peru. It is distinguishable immediately from the other two congeners by the shape of the hindwing underside submarginal orange band, and by the male genitalia. The systematics of Oressinoma are reviewed. A preliminary analysis is carried out based on COI barcode confirming the separate specific status of O. sorina n. sp. in relation to other two congeners. Both barcode and genital morphology data suggest that the widespread O. typhla Doubleday may be a complex of allopatric or, locally parapatric species. The genus Oressinoma is the only neotropical member of the predominantly Australian subtribe Coenonymphina, represented in the entire Holarctic by one genus only—Coenonympha Hübner, considered as the putative sister-genus of Oressinoma. Their origins and relationships are briefly discussed.
