Rhagomys is a genus of South American cricetids composed of three living species. They occur in eastern Andean
and lowland tropical forests. Since description of this genus more than a century ago, it was treated as an enigmatic
form within Sigmodontinae, varyingly thought to be allied to different suprageneric groups, with several scholars
highlig...
Thoroughly documenting prey items and diet composition is crucial for understanding a predator’s role in the ecosystem. In gape restricted predators, such as snakes, documenting and analyzing the type and size of the prey is important to interpret their ecological role. We describe the diet patterns of a species of venomous snake, the Terciopelo pi...
Ichthyomyini, a morphologically distinctive group of Neotropical cricetid rodents, lacks an integrative study of its systematics and biogeography. Since this tribe is a crucial element of the Sigmodontinae, the most speciose subfamily of the Cricetidae, we conducted a study that includes most of its recognized diversity (five genera and 19 species...
We name and describe a new species of Andean mouse from the eastern slope of the Andes of central Ecuador (Sangay National Park). This rodent is large-bodied (head-body length 167-184 mm) inhabiting the wet montane forest between 3,400-3,900 m in elevation. A molecular phylogeny based on mitochondrial genes resolved the new species as a member of t...
The Andean cloud forests of Ecuador are home to several endemic mammals. Members of the Thomasomyini rodents are well represented in the Andes, with Thomasomys being the largest genus (47 species) of the subfamily Sigmodontinae. Within this tribe, however, there are genera that have escaped a taxonomic revision, and Chilomys Thomas, 1897, constitut...
In 2012, we conducted a mammal survey in the cloud forest of the Otonga Forest Preserve on the western slope of the Andes in Cotopaxi Province, Ecuador. We used Sherman traps, Tomahawk traps, pitfall traps, and mist nets to collect mammal specimens at 2,070 m in elevation. We collected 148 specimens representing 19 species from the survey area. The...
The diversity of the oryzomyine rat Mindomys (Cricetidae, Sigmodontinae, Oryzomyini), is doubled here with the description of a new species from the remote Cordillera de Kutukú (Ecuador). The novel form can be easily differentiated from Mindomys hammondi-type species of the genus-by a large set of anatomical traits including, among others, larger j...
Nephelomys albigularis is a sigmodontine rodent of the tribe Oryzomyini distributed in the Andean forests from central Ecuador to central Peru. Although several studies recognize this species as monotypic, significant morphological variation has been reported in Peruvian populations that were not properly assessed by direct comparisons with the typ...
Describimos una nueva especie de roedor sigmodontino del género
Neacomys que habita en la cordillera del Cóndor, sureste de Ecuador. La nueva entidad se distingue fácilmente
de sus congéneres por la combinación de los siguientes caracteres: tamaño pequeño (longitud cabeza-cuerpo
�69 mm), cola larga (�55.5 % más que la longitud cabeza-cuerpo), vient...
The monotypic rodent Mindomys Weksler, Percequillo & Voss, 2006 (Cricetidae, Sigmodontinae) is one of the rarest members of the speciose tribe Oryzomyini. As this species is restricted to the Chocó forests of the western Andean slope in northern Ecuador, our knowledge is based on a few specimens collected decades ago. Here we add the first data on...
En este preprint, que nos enorgullece presentar a los colegas (para recibir los comentarios, críticas, adiciones, correcciones que deseen hacernos, a fin de enriquecerlo) distinguimos al enigmático género Rhagomys con una nueva tribu, a la par que ponemos en evidencia sus características únicas en el contexto de los Oryzomyalia. Más aún, proponemos...
A new species of the cricetid rodent genus Thomasomys is described from the montane forests of the Cordilleras del Cóndor and Kutukú, southeastern Ecuador, at elevations between 1,770 and 2,215 m. The species has a large body size (head and body length 137–147 mm) in comparison with other species in the genus, and also is distinguished from its con...
During a faunal survey in the foothills of the Ecuadoran Andes southwest of the Cordillera del Cóndor, a mouse of uncertain affinities was taken in a fishing net. Various external characters suggested that it was a member of the genus Rhagomys, previously unrecorded in Ecuador. Comparisons with the external, cranial, and dental morphology both of R...
Dando continuidad a esta línea que nos hemos planteado de compartir (máxime en estos tiempos tan duros que nos tocan) nuestras investigaciones ni bien son generadas, en forma de pre-print, acá presentamos un estudio donde hemos combinado la descripción de un magnífico nuevo representante de la tribu Oryzomyini de la remota Cordillera de Kutukú, en...
Quimsacocha National Recreation Area is located on the western slope of the Andes in Azuay Province, southern Ecuador. All sampling locations were in the high paramo and high Andean forests (3,572 to 3,865 m). The habitats include paramo, bogs, riparian, patches of elfin forests, and secondary cloud forest. We set Sherman, pitfall, and camera traps...
Mamíferos del Ecuador: lista actualizada de especies Mammals of Ecuador: updated checklist species- Tirira, Brito, Burneo y Comisión de Diversidad de la AEM (versión 2020.2)
The Andean cloud forests of western Colombia and Ecuador are home to several
endemic mammals; members of the Oryzomyini, the largest Sigmodontinae tribe,
are extensively represented in the region. However, our knowledge about this
diversity is still incomplete, as evidenced by several new taxa that have been described
in recent years. Extensive fie...
As geographic range estimates for the IUCN Red List guide conservation actions, accuracy and ecological realism are crucial. IUCN's extent of occurrence (EOO) is the general region including the species' range, while area of occupancy (AOO) is the subset of EOO occupied by the species. Data-poor species with incomplete sampling present particular d...
The Stripe-headed Round-eared bat, Tonatia saurophila, includes three subspecies: Tonatia saurophila saurophila (known only from subfossil records in Jamaica), Tonatia saurophila bakeri (distributed from southeastern Mexico to northern Colombia, Venezuela west and north of the Cordillera de Mérida, and northwestern Ecuador), and Tonatia saurophila...
Based on specimens collected
in the southeastern Andes of Ecuador, at Parque Nacional Sangay, but also including animals from mammal
collections, a revision of the species of the group “cinereus” of the cricetid genus Thomasomys Coues, 1884
(Sigmodontini, Thomasomyini) was made. As a result, concomitantly to a new phylogeny based on a molecular
mar...
Yacuri National Park, located on the South American continental divide in Loja Province,
Ecuador, was surveyed for mammals during four field trips (2009, 2014, 2015, and 2016). All sampling locations were along the western slope of the Andes (3,077−3,454 m) and included: páramo bogs, primary forests, lower páramo, páramo lagoon, a secondary forest,...
The northernmost Peruvian Andes, a unique biogeographic region characterized by the confluence of multiple distinct ecosystems (i.e. Amazon basin, Pacific rainforest, the Sechura Desert, the northern and central Andes), is the southernmost geographic range limit of the South American shrews representing the genus Cryptotis. In the northernmost Peru...
We describe a new species of climbing rat of the genus Rhipidomys based on cranial and external morphology, morphometrics, and phylogenetic analyses of cytochrome b gene. This taxon was compared with species of Rhipidomys present in Ecuador, principally R. latimanus, which is a closely related species based on molecular analysis, and with several s...
Herein we present a geographical review to the genus Glyphonycteris in Ecuador. We confirm the first record for G. sylvestris for the country, which extends its range about 680 km southwest of the nearest previously known record. This first record belongs to an individual captured in Sangay National Park, Morona Santiago province, eastern slopes of...
