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. [ABSTRACT FROM AUTHOR]

The genus Molossops includes two species that are restricted to South America: Molossops neglectus and Molossops temminckii. The smaller dog-faced dwarf Molossops temminckii is distributed from Colombia to Argentina and has a wide morphological variation and vocal plasticity. In Colombia, this species remains poorly known. To fill distributional gaps, we present novel records from Arauca, Atlántico, Bolívar, Córdoba, and Huila departments. We also present an analysis of the morphometric variation in South America using Principal Component Analyses. These show an external and cranial difference of specimens of Colombia in respect of other and South America populations. In Colombian landscapes dominated by the floodplain savanna of the Orinoco region, Molossops temminckii is smaller than in the other regions of the country, and the previously suggested existence of cryptic diversity within the taxon should be evaluated. Therefore, we suggest further integrative analyses to investigate a possible subspecific status of some Colombian populations. [ABSTRACT FROM AUTHOR]

Current knowledge on Colombian mammals has been based on specimens deposited in national or foreign collections and others that are part of passive sampling sensors. However, in recent years, regional collections are filling information gaps that complement available data on distribution, intra- and interspecific variation, and provide samples for phylogenetic analyses. We present information on 2112 records deposited in the Mammal Collection of the Museo de Historia Natural de la Universidad de Caldas, which to date constitutes the most complete collection in the Colombian Coffee Growing Region. Most records (n = 1412) come from the Department of Caldas, but there are records for 20 more departments. The most representative orders are Chiroptera (n = 1322 records) and Rodentia (n = 434). The collection houses two specimens used for the description of the endemic marsupial Marmosops chucha, as well as at least 363 specimens that have been referenced in national and foreign publications.
