Rhagomys longilingua is one of the rarest sigmodontine rodents of South America, currently known from only 2 localities (4 individuals) in Peru and Bolivia. Here we report 3 additional localities in Peru, one of which extends the geographic distribution range of this species 613 km northeast from the type locality (Suecia, Manu National Park, Cusco department). Potential distribution models showed the presence of R. longilingua from Bolivia until Colombia along the eastern slope of the Andes.

Evolutionary Aspects

New northwestern records of the striped treefrog Hypsiboas caingua (Carrizo, 1991 “1990”) are presented for Brazil, extending its known geographic distribution approximately 115 km northward (linear distance) of the previous northernmost record of the species. In all new localities, individuals of H. caingua were only found in calling activity under temperatures below 18°C. The species appears to be associated with Atlantic Forest, although it had already been recorded in Cerrado. Although the scientific literature data suggests that H. caingua presents discontinuous geographical distribution, three methods of distribution modelling based on climatic data show that the species' distribution is continuous. The gap in the distribution may be related to the lack of field surveys in the regions that connect these populations, especially in colder periods. Nevertheless, factors other than climate might also be responsible for the current distribution of H. caingua, since the species was absent in well-surveyed sites situated between the areas of modeled distribution. Therefore, further studies on natural history, populations' genetic structure, and geographic distribution models implementing factors other than climate will be important to elucidate some ecological and evolutionary aspects of the distribution of H. caingua in South America.

Geographic distribution of Rhyncholestes raphanurus Osgood, 1924 (Paucituberculata:Caenolestidae), an endemic marsupial of the Valdivian Temperate Rainforest

The Chilean shrew opossum (Rhyncholestes raphanurus) is the southernmost representative of the family Caenolestidae (Marsupialia : Paucituberculata). The species lives in temperate forests of southern Chile and Argentina and is currently known from <25 localities, spanning a latitudinal and longitudinal range of 2°44′ (~320 km) and 2°20′ (~190 km), respectively. Species distribution was analysed in a historical, geographic and biogeographic context, with the use of maps at different scales (region, subregion, province, ecoregion, forest types), and two potential distribution models were generated with MaxEnt. The models show a few isolated areas of high prediction values (>50%) in coastal Chile and the Andes from 39°30′ to ~42°S, and most of Chiloé Island, plus a northern and southern expansion of medium to low (<50%) prediction values. The most important environmental variables identified from the models include precipitation and some temperature-related variables. The species occurrence lies within the Andean region, Subantarctic subregion, and Valdivian biogeographic province. At a smaller scale, most of the localities occur in eight of the 22 forest types described for the Valdivian ecoregion, implying narrow ecological requirements. Identification of critical areas through potential distribution modelling may have implications for species conservation and identification of biogeographic patterns.

The lesser grison (Galictis cuja) is one of the least-known mustelids in the Neotropics, despite its broad range across South America. This study aimed to explore current knowledge of the distribution of the species to identify gaps in knowledge and anticipate its full geographic distribution. Eighty-nine articles have mentioned G. cuja since 1969, but only 13 focused on the species. We generated a detailed model of the species' potential distribution that validated previous maps, but with improved detail, supporting previous southernmost records, and providing a means of identifying priority sites for conservation and management of the species.

Manu National Park

To reach the Manu National Park means a day's journey by road over the Andes from Cusco, climbing up to the high puna grassland where one enters the park at the Tres Cruces guard post, 3300m above sea level. The last part of the road down to Shintuya at 300m has four unbridged river crossings that are impassable in the wet season from November to March. At Shintuya, if no park boat is available, the onward journey to Pakitsa, the administrative headquarters where there is accommodation, can only be made by hiring the Dominican Mission boat at $100 a day plus 30 gallons of gasoline (if you can get it) as well as enough for the return journey from Pakitsa to Cashu Cocha.

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

Magnolia mercedesiarum, a new species from the eastern slopes of the Andes in northern Ecuador, is described and illustrated, and a key to Ecuadorian Magnolia (subsect. Talauma) is provided. This species differs from M. vargasiana in having broadly elliptic leaves that have an obtuse base vs. suborbicular and subcordate to cordate, glabrous stipular scars, more numerous lateral veins per side and fewer stamens. It also differs from M. llanganatensis in having leaf blades broadly elliptic vs. elliptic, longer petioles, less numerous lateral leaf veins per side, larger fruits and more numerous petals and carpels. Using MaxEnt species distribution models and IUCN threat criteria, M. mercedesiarum has a potential distribution area of less than 3307 km² and is assessed as Endangered (EN): B1 ab (i, ii, iii). The relevance of systematic vegetation sampling in the discovery of rare species is highlighted.

Taxonomical Study

The pitcairnioid genus Fosterella currently comprises 31 species distributed from Mexico in North America, along the eastern slopes of the Andes in central South America, Southern Peru to northern Argentina, encompassing western, northern and southeastern Brazil and northern Paraguay. Their species have rather small ranges, representing local endemics traditionally difficult to circumscribe mainly because the presence of subtle morphological characters associated to tiny floral parts. The present taxonomical study of the Fosterella species occurring in Brazil is founded on morphological characters, habitat preference, and geographic distribution. The number of Brazilian species is increasing to eight, three of them described as new here, including an unexpected outlier in geographical range and two new records for the country. Full descriptions and an identification key are provided, and morphological relationships are discussed as well.

I report an aberrant record of Hoatzin Opisthocomus hoazin in the Andes of Lara, Venezuela. During field work in July 2011 in the Yacambú National Park, in an area of premontane cloud forest, I observed and photographed an individual of O. hoazin in El Blanquito reservoir. This is the first record of the species in Lara State, and apparently the highest record of the species in northern South America.
