“…The lack of phylogenies involving all species living in Colombia and the missing morphological information associated with molecular analyses to support proper identification of voucher specimens in national collections have limited the understanding of species richness and distribution. Although Colombia is a country rich in shrew species relative to other South American countries (Table 5; Solari et al 2013;Quiroga-Cardona and DoNascimiento 2016;Moreno Cárdenas and Román-Carrión 2017;Zeballos et al 2018), this number appears to be underestimated, given the complexity of the Andean ecosystems. For example, there are reports on the presence of Cryptotis specimens lacking the morphological traits of the species known for the Central Cordillera (Sánchez and Alvear 2003;Rojas-Díaz et al 2012;Figure 5).…”

In Colombia, shrews (Cryptotis) are represented by seven species associated with Andean, high Andean, and Paramo ecosystems of the three national Cordilleras. Of these species, five are endemic to the Andean region of the country. Despite representing the group of mammals with the highest rate of endemic species, the knowledge currently available on aspects such as natural history, distribution, and ecology is limited. This work assesses the current state of knowledge of the shrews of Colombia, discusses taxonomic issues, risks and threats related to conservation, and identifies research needs and priorities. We compile the information on shrews of Colombia available in the literature and databases. We include two of the known species of the country and one to be determined within a phylogenetic context. In general, the knowledge of the shrews of Colombia reveals the lack of ecological and genetic studies. There are unsolved taxonomic questions about the presence of certain species in the different mountain ranges of the country. There is an urgent need to generate molecular information to clarify the richness of the genus in Colombia which, according to our observations, has been underestimated. The knowledge about the shrews of Colombia is still scarce, even when some species were first described more than a hundred years ago. The need to conduct systematic studies and comprehensive morphological descriptions to clarify the richness of the shrews of Colombia is highlighted.En Colombia, las musarañas (Cryptotis), están representadas por siete especies asociadas a ecosistemas andinos, altoandinos y paramunos de las tres cordilleras nacionales. De estas especies, cinco son endémicas de la región andina del país. A pesar de representar el grupo de mamíferos con mayor porcentaje de especies endémicas, el conocimiento que tenemos sobre aspectos como historia natural, distribución y ecología, es casi nulo. Este trabajo evalúa el estado actual de conocimiento de las musarañas de Colombia, discute problemas taxonómicos, riesgos y amenazas para su conservación e identifica necesidades y prioridades de investigación. Compilamos la información disponible en literatura y bases de datos sobre las musarañas de Colombia. Ubicamos a 2 de las especies conocidas en el país y una por determinar en un contexto filogenético. La tendencia general en el conocimiento de las musarañas de Colombia es hacia la ausencia de estudios ecológicos y genéticos. Además, aún persisten dudas taxonómicas con respecto a la presencia de ciertas especies en las diferentes cordilleras del país. Existe una necesidad urgente de generar información molecular para clarificar la riqueza real del género en Colombia que, de acuerdo con nuestras observaciones, ha sido subestimada. El conocimiento sobre las musarañas de Colombia es aún precario, a pesar de que algunas especies fueron descritas hace más de cien años. Se resalta la necesidad de generar estudios sistemáticos y de profundizar en descripciones morfológicas más completas que permitan clarificar la riq...

“…The shrews of the genus Cryptotis, which includes about 43 species, are distributed from the eastern United States and southern Canada through Central America and northwestern South America (He et al 2015;Quiroga-Carmona and Woodman 2015;Quiroga-Carmona and DoNascimento 2016). It is the only genus of the order Eulipotyphla found in South America, and the Huancabamba Depression region in the Andes of northern Peru is the southernmost limit of its geographic range (Tate 1932;Vivar et al 1997;Woodman 2002;Woodman and Péfaur 2008).…”

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 Peruvian Andes, two poorly known species have traditionally been reported (C. peruviensis and C. equatoris). Our study, based on molecular and morphologic traits, confirms the presence of C. peruviensis but also the occurrence of C. montivaga, based on specimens erroneously assigned to C. equatoris. Moreover, a new species of Cryptotis from the páramo and montane forests of the Tabaconas Namballe National Sanctuary near the Ecuadorian border is also described. It is a member of the thomasi group and is distinguished from other South American shrews by a unique set of morphological characters, including large body size, comparatively short tail, simple ectoloph of M3, and large PM4 post protocrista.

“…Small-eared Shrew, Cryptotis equatoris (O. Thomas, 1912), the Northern Ecuadorian Small-eared Shrew, C. niausa Moreno Cárdenas & Albuja, 2014, and the Osgood's Small-eared Shrew Cryptotis osgoodi (Stone, 1914) (Moreno Cárdenas and Albuja 2014;Zeballos et al 2018). However, the presence of C. equatoris and C. niausa is expected in Colombia, because of the vegetation similarities and the lack of geographic or other ecological barriers between the Andean part of southwestern Colombia and northern Ecuador (Ramírez-Chaves and Noguera-Urbano 2011; Noguera- Urbano et al 2019).…”

“…Cryptotis niausa is currently known from nine localities in the Ecuadorian provinces of Carchi, Napo, and Pichincha, ranging in elevational from 2,865 to 3,910 m a.s.l. (Moreno Cárdenas and Albuja 2014; Zeballos et al 2018), with an estimated Extent of Occurrence (EOO) of 5,036 km² (Roach and Naylor 2020). It is among the largest Cryptotis (head and body length: 74-89 mm; condylo-basal length: 21.8-23.7 mm), and it can be differentiated by its size, cranial and dental characters, and genetic data (Moreno Cárdenas and Albuja 2014; Zeballos et al 2018).…”

In Colombia, seven species of small-eared shrews of the genus Cryptotis Pomel, 1848 have been reported, and five of them endemic to the country. Here, we present the first confirmed record from Colombia of Cryptotis niausa Moreno Cárdenas & Albuja, 2014, a species that was previously known from only nine localities in Ecuador. The Colombian record comes from the Departamento de Nariño, in extreme southwestern Colombia, and it is supported by morphology and cytochrome-b gene evidence. This record increases to eight the number of species of Cryptotis from Colombia.
