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.

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

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.

Frequent biodiversity sampling and monitoring programs often lead to relevant taxonomic findings. Here, as a product of different field expeditions to two places in the northern Andes, we discover and describe two new species of rain frogs of the genus Pristimantis from the cloud forests of the Central Cordillera of Colombia. Pristimantis chocolatebari sp. nov. is diagnosed by having the following character states: dentigerous process of vomer triangular, snout large and protruding, dorsum smooth, vocal slits and vocal sac present, groin and hidden part of the thighs yellow. Pristimantis carylae sp. nov. is diagnosed by having iris copper red, dentigerous process of vomer oval, snout short and rounded, dorsum finely shagreen with scattered tubercles, double nuptial pad in males, groin and hidden part of thighs pink. We also infer, for the first time, the phylogenetic position of P. permixtus, P. platychilus, and two candidate new species. In addition, we emphasize not to use genetic distance as the only source of evidence for species delimitation, considering the high intraspecific diversity found in one of the species described here. Finally, we highlight the relevance of different habitat and ecosystem conservation strategies to promote amphibian diversity studies in the Andes.

A New Species

We describe a new species of Selvasaura from the montane forests of the eastern slopes of the Andes in northern Peru, based on external and hemipenial morphological characters and previous phylogenetic analyses. The new species can be differentiated from the other two Selvasaura species in having keeled dorsal scales usually flanked by longitudinal striations, in adults and juveniles; adult males with a yellow vertebral stripe bordered by broad dark brown stripes on each side and a unilobed hemipenis surrounded by the branches of the sulcus spermaticus. The description of the new species contributes information about new states of diagnostic characters of Selvasaura and natural history.

Clinanthus fabianae and C. thiagoi are described from Ancash and La Libertad departments of Peru. Both species have similar perigone coloration, broadly lobed staminal coronas, and incurved free filaments. They may represent a distinct species group, along with the previously described C. inflatus. The species can be separated by number of flowers, pedicel length, flower habit, tube length, morphology and pattern of dilation, and color of the tepal apiculum.

Two New Species

Two new species, Passiflora splendida and P. quinonesiae of the section Colombiana from the Andes of Cundinamarca Department (Colombia Eastern Cordillera) are described and illustrated. Passiflora splendida is morphologically similar to P. cremastantha of the series Leptomischae, but can be distinguished by its linear stipules, petioles up to 1.8 cm long, lance-ovate leaves (6–8.5 × 2.5–3.3 cm), flowers with a diameter of 9–11 cm long, sepals and petals with intermediate disposition, both longer than the floral tube, floral tube of 3.2–4.5 cm long and fusiform ovary. Passiflora quinonesiae is similar to the species of series Colombianae, most closely related to P. cuatrecasasii and P. lanata. It differs from P. cuatrecasasii by its terete stem, size of the leaves 4.4–15 × 10.3 cm, elliptic bracts and floral tube 5.2–6 cm long. It differs from P. lanata by its ovate leaves, bracts halfway down the floral tube, elliptical sepals and petals, and elliptical ovary. In addition, a taxonomic key to section Colombiana ser. Colombianae and Leptomischae for Colombia is included and information about the ecology, distribution, and conservation status of P. splendida and P. quinonesiae are discussed.

Two new species of Leptanilloides are described: L. copalinga Delsinne & Donoso sp. nov., and L. prometea Delsinne & Donoso sp. nov., based on workers collected in the leaf litter and soil of the Andes of southern Ecuador. Both species belong to the L. biconstricta species-group (formally diagnosed here). The metatibial gland, considered a synapomorphy for Dorylinae, is observed in L. prometea sp. nov. but seems absent in L. copalinga sp. nov. We provide a COI DNA barcode for both species and a revised key for the worker caste of all known species in the genus. We also describe a single male identified as a potential new Leptanilloides species on the basis of morphology. Furthermore, its mitochondrial COI gene sequence does not match any previously barcoded species. However, we refrain from giving it a specific name because of our lack of knowledge about the worker caste. So far, half of the 14 Leptanilloides species have been discovered above 1500 m in the mountain forests or páramos of the Ecuadorian Andes, confirming, if needed, the biological significance of these threatened habitats.
