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

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.

A New Species

AbstractA new species of Hyla is described from cloud forests of the Cosñipata Valley in southern Peru. The new species lacks webbing in hands and has vestigial webbing between toes III and IV, is readily distinguished from any other species of Andean Hyla, and is not clearly assignable to any species group. The new species seems to be a secretive, bromeliad-dweller.

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.

A New Species

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 Noblella from the western slope of the Ecuadorian Andes. The new taxon is distinguished from all other species in the genus by lacking dorsal marks (i.e., interobital bar, scapular and sacral chevrons) and by having a bright orange venter. The new species and Noblella heyeri are the only species of Noblella reported in the Pacific Andean versant. We provide an osteological description of the new species and a key for the species in Noblella.

A New Species

A new species of the genus Colias Fabricius from the Arequipa region of Peru, C. misti Kir’yanov sp. nov., stat. nov., is established by raising it from the subspecies rank, C. lesbia misti Kir’yanov 2017. This taxonomic act is justified after detailed comparison of C. misti with representatives of phenotypically similar other South American Colias, including the subspecies of C. lesbia. The newly presented taxa are diagnosed by adult morphology, bionomics, and male genitalia. The diagnosis of a new subspecies Colias misti ccota Kir’yanov ssp. nov., discovered in the World’s deepest canyon Cotahuasi (Peru), is based on different and stable characters in phenotypes, genitalia, and bionomics of C. misti ccota and C. misti misti. Both subspecies of C. misti are endemic to the Western slopes of the Andes. It is also demonstrated that the shape of the male aedeagus is diagnostic for a reliable identification of the South American Colias.

A new species of Osteocephalus (Anura: Hylidae) from Colombia, with comments on the morphological and behavioral diversity within the genus. A striking, undescribed species of Osteocephalus from the Amazonian slopes of the Andes in Departamento de Putumayo in southern Colombia is a member of the Osteocephalus buckleyi Group. Aside from minor morphological characters, the new species differs from all other members of the group by having a golden yellow iris with a median horizontal black stripe. The diversity in morphological and reproductive behavior reveals various features that are phylogenetically signifcant, but several species remain to be described.
