A new species from the Northern Peruvian Andes (Cajamarca department), Drymaria veliziaesp. nov., is proposed in the present paper. It grows in the high-elevation montane grasslands and it is morphologically similar to D. auriculipetala from which it differs in having elliptic-ovate leaves, blade margin bases glandular, large number of stipules arranged in a pedicel form at the leaf axis and by the short and glandular pedicels. A detailed description, original photographs and a location map are provided, as well as an updated diagnostic key of Drymaria Ser. Frutescens. The IUCN status of the new species is assessed as Endangered (EN).

A New Species

The grass genus Poa L. is widespread throughout temperate areas of the Andes, being a common constituent in the highly diverse but threatened high-elevation páramo grasslands of northwest South America. Knowledge of Poa from these páramo areas is very limited, however, with no comprehensive taxonomic treatments available for Colombia, which contains the largest area of páramo in the Neotropics and its surrounding countries. We present a taxonomic revision of Poa for Colombia accepting 15 species, including two recent combinations of Poa previously circumscribed in Aphanelytrum (Hack.) Hack. We describe a new species, P. colombiana Soreng & Sylvester, and a new variety, P. subspicata (J. Presl) Kunth var. glabrata Soreng & Sylvester, for Colombia and Ecuador. Poa colombiana is similar to P. aequatoriensis Hack. but differs in having lemmas pubescent on the keel and marginal veins, lemma apices weakly acute, flag leaf sheath margins fused 20%–38% their length, and anthers generally larger, > 1.2 mm long. Poa subspicata var. glabrata differs from P. subspicata s. str. in having glabrous lemmas. We provide two new records for Colombia of P. huancavelicae Tovar, and P. mucuchachensis Luces. Two species, P. orthophylla Pilg. and P. reclinata (Swallen) Soreng & P. M. Peterson, are considered endemic to Colombia. Poa soderstromii Negritto & Anton is placed as a subspecies of P. orthophylla, and P. leioclada Hack. is synonymized under P. mulalensis Kunth. The names P. annua L. var. exilis Tomm. ex Freyn, P. humilis Ehrh. ex Hoffm., P. infirma Kunth, P. leioclada, P. orthophylla, P. pauciflora Roem. & Schult., P. pratensis L. subsp. irrigata (Lindm.) H. Lindb., P. puberula Steud., P. pubiflora Benth., P. subcaerulea Sm., P. subspicata, and P. trachyphylla Pilg. are lectotypified, P. mulalensis is neotypified, and P. trachyphylla is epitypified. Four species are exotic and introduced from Europe: P. annua, P. infirma, P. pratensis, and P. trivialis L. We provide a key, descriptions, illustrations, distribution and habitat information, vouchers, and notes for each species.

A New Species

Atelopus pachydermus is redescribed on the basis of the retraced holotype and recently collected specimens. Comparisons with the holotype confirmed that this species occurs neither in Pacific Colombia, nor in the northeastern Cordillera of Ecuador, as proposed by previous authors. It occurs in the northwestern Andes of Peru and adjacent Ecuador. Populations from the Cordillera Oriental in northern Ecuador (some of them previously allocated to A. pachydermus) are described as a new species, which is distinguished from other Atelopus by size, coloration, and by having white digital pads that contrast with adjacent black phalanges. In addition, a population of Atelopus from the Andes of southwestern Ecuador, previously included in the Atelopus bomolochos complex, and having an aqua blue iris is described as a new species. We include osteological data of both new species. Predictions of numbers of species of Atelopus to be discovered and described, as well as of numbers for Ecuadorian amphibian diversity, indicates that these faunas are yet largely undescribed. Because recent records of A. pachydermus and the two new species are lacking despite search efforts, we assume that they are possibly extinct, similar to many other Andean Atelopus. Thus, we categorize these species either aspossibly extinct or, applying IUCN Red List criteria, as Critically Endangered. Current evidence suggests that amphibian extinctions in the Ecuadorian and Peruvian Andes have been more drastic than previously recognized.

Crocidosema nitsugaisp. nov. (Lepidoptera, Tortricidae, Olethreutinae, Eucosmini) is described and illustrated from the Andes of northern Chile based on adults obtained from larvae collected on leaves, flowers and unripe fruits and seeds of Lupinus oreophilus Phil. (Fabaceae). This represents the first record of insect herbivory on this Chilean endemic perennial herb. The genitalia morphology of C. nitsugai suggests a close evolutionary relationship with two congenerics from high elevation environments of the Ecuadorian and Peruvian Andes.

A New Species

We describe a new species ofPsychrophrynellafrom the humid montane forest of the Department Cusco in Peru. Specimens were collected at 2,670–3,165 m elevation in the Área de Conservación Privada Ukumari Llakta, Japumayo valley, near Comunidad Campesina de Japu, in the province of Paucartambo. The new species is readily distinguished from all other species ofPsychrophrynellabutP. bagrecitoandP. usurpatorby possessing a tubercle on the inner edge of the tarsus, and from these two species by its yellow ventral coloration on abdomen and limbs. Furthermore, the new species is likeP. bagrecitoandP. usurpatorin having an advertisement call composed of multiple notes, whereas other species ofPsychrophrynellawhose calls are known have a pulsed call (P. teqta) or a short, tonal call composed of a single note. The new species has a snout-vent length of 16.1–24.1 mm in males and 23.3–27.7 mm in females. Like other recently described species in the genus, this newPsychrophrynellainhabits high-elevation forests in the tropical Andes and likely has a restricted geographic distribution.

A New Species

To date, only one species of Temnocephala is known from Chile, Temnocephala chilensis, and three from southern Argentina (Patagonia), namely T. chilensis, Temnocephala dionii, and Temnocephala mexicana. Here we describe a new species of Temnocephala and provide an updated description of T. chilensis based on material found on an anomuran crab (Aeglidae) from southern Chile. Additional hosts and localities are reported for both species in southern Argentina and Chile, and a diagnostic key for all species of Temnocephala hosted on Aegla and Parastacidae is included as well. In southern Chile, both T. chilensis and the new species were found on the crayfish Samastacus spinifrons and on the anomuran crabs Aegla abtao and Aegla alacalufi; in addition, the new species was found on Aegla manni, and T. chilensis on Aegla rostrata. In southern Argentina, T. chilensis and the new species were found on Aegla riolimayana and S. spinifrons. Based on their shared traits (morphology of the penial stylet, host preferences and geographic distribution), the temnocephalans hosted in Aegla are tentatively gathered into two clusters, the Chilensis and Axenos groups.

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.

Lecidea hercynica Hauck & Schmull is described as a new species from Germany. It is characterized by a poorly developed or bullate to verrucose, areolate thallus on whitened spots of the substratum, numerous plane to yellowish brown to black, convex apothecia with a persistent margin, Micarea type-like asci, and by the presence of atranorin and protocetraric acid. It does not belong to Lecidea s. str., but is provisionally placed in Lecidea s. lat. until a taxonomic treatment of the whole group has been carried out. Lecidea hercynica is widespread in high-elevation forests of Picea abies in the Harz Mountains, where it grows preferably on decorticated wood in open situations.

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.
