A new species of Calceolaria endemic to central Chile is described. A comparison with morphologically similar species is made, and a key as well as detailed images to differentiate them is provided. The species is only known from the Natural Sanctuary Cerro El Roble, which is part of the coastal mountain range of central Chile and can be considered as  Critically Endangered (CR) under the IUCN categories and criteria.

The Pudu deer (Pudu puda) is endemic to the temperate rainforest of Chile and Argentina and currently faces serious conservation problems related to habitat loss. However, studies undertaken on this species are not sufficient to identify suitable areas for conservation purposes across its distribution range. In order to estimate the current and future distribution of the Pudu deer in southern Chile, we modelled the potential distribution of this species, based on occurrence points taken from seven contiguous provinces of this area using the Maxent modelling method. The Pudu deer distribution covered an estimated area of 17,912 km2 (24.1% of the area analysed), using a probability of occurrence above 0.529, according to the threshold that maximises the sum of sensitivity and specificity. In contrast to the Andes mountain range, areas with higher probabilities of occurrence were distributed mainly on the eastern and western slopes of the Coastal Mountain Range, where extensive coverage of native forest persists, as occurs in the provinces of Ranco, Osorno and Llanquihue. Projections to 2070, with global warming scenarios of 2.6 and 8.5 rcp, revealed that large areas will conserve their habitability, especially in the Coastal mountain range. Our results reveal that the Coastal mountain range has a high current and future habitability condition for the Pudu deer, a fact which may have conservation implications for this species.

ABSTRACT An oceanic deep lies off the Chilean coast, bordered on the east by a coastal mountain range, a discontinuous central valley, and the high cordillera of the Andes. The Chilean volcanoes are found on lineaments that in general coincide with, or are sub parallel to, axis of the Andes. In north Chile they lie along en echelon fractures and, in some cases, along transverse fractures. In the south, the alignment of the volcanoes lies west of the axis of the Andes. Where the Central Valley is not well developed, active volcanoes are scarce. Recent lavas range from basalt in the south to rhyolite in the north. Volcanic activity appears to be decreasing. Details are given of individual volcanoes, and a list of active Andean volcanoes south of Volcan Misti is presented with a historical account of their activity.

Resumen:Antecedentes y Objetivos: El Parque Nacional Macarao es un área natural protegida ubicada cerca de la ciudad de Caracas, capital de Venezuela. Apesar de su ubicación estratégica, es un área poco explorada biológicamente; el desconocimiento briológico es sustancial. El objetivo fundamental deeste trabajo fue inventariar los briofitos del Parque Nacional Macarao.Métodos: Se plantearon tres ejes para evaluar la flora de musgos, hepáticas y antoceros del Parque Macarao: una revisión bibliográfica de reportespara el área de estudio, una revisión de herbarios nacionales (CAR, MY, VEN) y extranjeros (MO, NY, TROPICOS) y un inventario brioflorístico sobretodos los sustratos disponibles a lo largo de siete localidades ubicadas entre 1500 y 2600 m s.n.m. Los ejemplares colectados se identificaron conclaves taxonómicas especializadas; posteriormente, fueron depositados en los herbarios MO y VEN.Resultados clave: La información obtenida provino en 76% del inventario florístico, 19% revisión bibliográfica y 5% material de herbario. Se elaboróuna lista con 114 especies distribuidas en 77 géneros y 42 familias de briofitas (70 especies de musgos y 44 hepáticas). Las familias con mayor númerode especies fueron Lejeuneaceae (13 géneros/21 especies), Orthotrichaceae (2/7), Sematophyllaceae (3/6), Fissidentaceae (1/6), Pilotrichaceae (4/4)y Neckeraceae (5/5).Conclusiones: Se incluyen 87 nuevos registros para el Parque Nacional Macarao y se reporta por primera vez Calymperes tenerum para Venezuela.Se recomienda incluir, según los criterios de la UICN a Steerecleus serrulatus y Rhaphidorrhynchium decurvifolium como especies vulnerables dentrode la brioflora venezolana.Palabras clave: Cordillera de la costa, hepáticas, inventario, musgos.Abstract:Background and Aims: The Macarao National Park is a protected area located near the city of Caracas, capital of Venezuela. Despite its strategiclocation, it is biologically little explored; the lack of bryological knowledge is substantial. The fundamental objective of this work was the inventory ofthe bryophytes of the Macarao National Park.Methods: Three actions were proposed to evaluate the flora of mosses, liverworts and anthocyanins of this park: bibliographic review of reports forthe study area, herbarium review of different national (CAR, MY, VEN) and foreign herbaria (MO, NY, TROPICOS), and floristic inventory made on allavailable substrates across seven locations located between 1500 and 2600 m a.s.l. The collected specimens were identified with specialized taxonomickeys; subsequently, they were deposited in the herbaria MO and VEN.Key results: Seventy-six percent of the information was obtained from the floristic inventory, 19% from the bibliographic review and 5% from herbariummaterial. In this way, a list was prepared consisting of 114 species, distributed in 77 genera and 42 families of bryophytes (70 species of mossesand 44 liverworts). The families with the highest number of species were Lejeuneaceae (13 genera/21 species), Orthotrichaceae (2/7), Sematophyllaceae(3/6), Fissidentaceae (1/6), Pilotrichaceae (4/4) and Neckeraceae (5/5).Conclusions: Among the highlighted results, 87 new records are included for Macarao National Park and Calymperes tenerum is reported for Venezuelafor the first time. It is recommended to include, according to the IUCN criteria, Steerecleus serrulatus, Rhaphidorrhynchium decurvifolium asvulnerable species within the Venezuelan bryoflora.Key words: Coastal mountain range, inventory, liverworts, mosses.
