A new species of Pristimantis (Amphibia, Anura, Craugastoridae) from the foothills of the Andes in Manu National Park, southeastern Peru

Andaeschna is a small and poorly known genus of dragonflies that inhabits the Andes, from Venezuela to northwestern Argentina. Here we describe Andaeschna occidentalis sp. nov., first species of the genus recorded in the Western Andes, specifically from the Tatamá National Park in Colombia. Males of this species can be differentiated from the other four species in the genus by the unique shape of the distal segment of the vesica spermalis. Likewise, females can be distinguished by their smaller and broader cerci (slightly shorter than S9) and its subquadrate point. The discovery of this beautiful species expands the range of the genus, previously known only in the Eastern Andes.

A New Species

We describe a new species of glassfrog from the cloud forest of Manu National Park, southern Peru, at elevations of 2750–2800m. The new species is similar in morphology to Centrolene lemniscatum, which occurs in northern Peru at elevations of2000–2280 m. Both species have white labial stripes, humeral spines, and lack vomerine teeth. The new species differs from C.lemniscatum by its larger size, labial stripe extending into a distinct lateral stripe instead of a discontinuous lateral stripe, snoutprofile inclined anteroventrally instead of bluntly rounded, greater depression in the internarial area, and by having stronglyprotruding nostrils. Males of the new species emit long calls with 8–14 peaked notes, instead of a short tonal note in C. lemnis-catum. Another morphologically similar species, C. buckleyi, has a short advertisement call composed of 1–5 notes, and isgenetically distinct from the new species. This new Centrolene extends the known distribution of Centrolene to the south by 600 km, and is the southernmost species of this genus.

A New Species

We describe a new species of Enyalioides from a mid-elevation premontane forest in central Peru. This represents the seventh species of Enyalioides known to occur east of the Andes in South America; the other six species are E. cofanorum, E. laticeps, E. microlepis, E. palpebralis, E. praestabilis, and E. rubrigularis. Among other characters, the new species is distinguished from other Enyalioides by the combination of an orange blotch on the antehumeral region (in adult males), 30 or fewer longitudinal rows of dorsals in a transverse line between dorsolateral crests at midbody, ventral scales strongly keeled, and caudal scales heterogeneous in size on each autotomic segment. The new species is most similar morphologically to E. cofanorum and E. microlepis.

A New Species

We describe a new species of Lynchius from the eastern montane forest of southern Ecuador. We also report the occurrence of L. parkeri in Ecuador, on paramos of Yacuri National Park, near the border with Peru. We used morphological and genetic evidence for the description of the new species and the new report of L. parkeri. Phylogenetic analyses were carried out using both maximum likelihood and Bayesian inference on DNA sequences for mitochondrial and nuclear genes. The phylogeny shows that L. simmonsi is sister to a clade composed of the remaining species of Lynchius and that the new species is sister to L. flavomaculatus. The new species has a prominent and heavily ossified head with noticeably spiculate cranial exostosis that easily distinguishes it from all its congeners. The dorsal region and limbs present several reduced subconical and rounded tubercles and pronounced dermal ridges on the dorsum. We also describe the osteology of the new species based on x-rays of the holotype. Only six species of Lynchius, two known to occur in Ecuador (L. flavomaculatus and L. simmonsi). The description of L. megacephalus sp. n. and new record of L. parkeri double the number of known Lynchius in Ecuador and suggest that the diversity of Ecuadorian and Peruvian Lynchius is still underestimated.

Manu National Park

We describe two new species of Pristimantis from the Kosñipata valley in the eastern slopes of the Andes near Manu National Park, Peru. The two new species are closely related but do not overlap elevationally: P. antisuyu sp. n. occurs from 1485–1823 m a.s.l., whereas P. erythroinguinis sp. n. occurs from 930–1255 m a.s.l. Both species are readily distinguished from all other species of Pristimantis but P. cruciocularis and P. flavobracatus by possessing an iris with a cruciform pattern, no tympanum, and red bright or yellow coloration on groin. We used a Maximum Likelihood approach to infer a molecular phylogeny on a dataset composed of 27 terminals and 903 bp of the concatenated 16S rRNA and COI mitochondrial fragments. Our phylogenetic analyses indicate that, despite differing in groin coloration from red to yellow, individuals of P. cruciocularis and P. flavobracatus form a single clade, and some specimens have identical 16S sequences. Therefore, we synonymize P. flavobracatus with P. cruciocularis. The two unnamed species are closely related to P. cruciocularis. Pristimantis antisuyu sp. n. differs from P. cruciocularis and P. erythroinguinis sp. n. by having smaller yellow spots, instead of extensive red coloration, on groin and hind limbs, by being larger with proportionally longer tibias, and by having an inner metatarsal tubercle three times the size of outer metatarsal tubercle (twice as long in the other two species). Pristimantis erythroinguinis sp. n., despite having coloration very similar to P. cruciocularis, is the sister taxon to both P. antisuyu sp. n. and P. cruciocularis, and can be distinguished from the latter by having much darker ventral coloration, and no cream or yellow spots on flanks and surrounding the red inguinal marks.

Lines Of Evidence

Abstract The systematics and taxonomy of the broadly distributed bats of the genus Cynomops has changed considerably in the last few years. Among the major changes, Cynomops abrasus was split into two species of large-bodied forms (Cynomops mastivus and C. abrasus) distributed east of the Andes. However, large Colombian specimens identified as C. abrasus from the western side of the Andes had yet to be included in any revisionary work. Phylogenetic analysis performed in this study, using mtDNA sequences (Cytochrome-b), revealed that these Colombian individuals are more closely related to Cynomops greenhalli. Morphological and molecular data allowed us to recognize populations from western Colombia, western Ecuador and northwestern Peru, as members of a new species of Cynomops. Characters that allow for its differentiation from C. greenhalli include a larger forearm, paler but more uniform ventral pelage, more globular braincase, and well-developed zygomatic processes of the maxilla (almost reaching the postorbital constriction). This study serves as another example of the importance of including multiple lines of evidence in the recognition of a new species. Given its rarity and the advanced transformation of its habitat, this new species is particularly important from a conservation perspective.

A New Species

Abstract During a parasitological survey of fishes at Iguazu National Park, Argentina, specimens belonging to the allocreadiid genus Auriculostoma were collected from the intestine of Characidium heirmostigmata. The erection of the new species is based on a unique combination of morphological traits as well as on phylogenetic analysis. Auriculostoma guacurarii n. sp. resembles four congeneric species – Auriculostoma diagonale, Auriculostoma platense, Auriculostoma tica and Auriculostoma totonacapanensis – in having smooth and oblique testes, but can be distinguished by a combination of several morphological features, hosts association and geographic distribution. Morphologically, the new species can be distinguished from both A. diagonale and A. platense by the egg size (bigger in the first and smaller in the last); from A. tica by a shorter body length, the genital pore position and the extension of the caeca; and from A. totonacapanensis by the size of the oral and ventral sucker and the post-testicular space. Additionally, one specimen of Auriculostoma cf. stenopteri from the characid Charax stenopterus (Characiformes) from La Plata River, Argentina, was sampled and the partial 28S rRNA gene was sequenced. The phylogenetic analysis revealed that A. guacurarii n. sp. clustered with A. tica and these two as sister taxa to A. cf. stenopteri. The new species described herein is the tenth species in the genus and the first one parasitizing a member of the family Crenuchidae.
