“…Numerous studies have been published on the characteristics of hair morphology. The researchers showed that by combining hair characteristics such as cuticle, medulla, cortex, diameter, colour and size it would be possible to differentiate between species (Caldara & Leite, 2012; Cavia et al., 2008; De Marinis & Asprea, 2006; Duarte & Lessa, 2015; Keogh, 1985; Lee et al., 2014; Perrin & Campbell, 1980; Silveira et al., 2013; Teerink, 2003; Wade et al., 2018). Thus, systematic mammalian identification keys based on the variability of hair characteristics are established, showing the identification of species (Lee et al., 2014).…”

“…Thus, one should expect some variability between species and relative uniformity within them (Caldara & Leite, 2012; Silveira, Sbalqueiro, & Monteiro, 2013). Studies have shown that hair features such as the cuticle, the medulla, the cortex, hair diameter, the colour and length can be used to differentiate between species (Caldara & Leite, 2012; Cavia et al., 2008; De Marinis & Asprea, 2006; Duarte & Lessa, 2015; Lee et al., 2014; Silveira et al., 2013; Teerink, 2003; Wade, Stokes, & Spencer, 2018). As a result, several systematic hair identification keys were established to distinguish between mammal species belonging to orders such as Rodentia, Lagomomorpha, Carnivora, Artiodactyla, Inserctivora and Chiroptera (Keogh, 1985; Lee et al., 2014).…”

Distinguishing Central African rodents and shrews using their hair morphology

Species identification methods are needed for small mammals. Herein, we present a simple and efficient identification key based on the hair morphology of Central African rodents (Rodentia) and shrews (Soricomorpha). A total of 1,320 museum hair samples from 51 species were analysed with an optical light microscope. One‐third (31.37%) of these samples could be identified to the species level using four morphological characters (medulla, cuticle, size and colour). The remaining species formed nine groups of two to 10 species each which could not be discriminated because of overlapping characteristics between different taxa. In addition, shrew, dormice and squirrel hair samples were clearly distinguishable from the other samples because they were either shorter (0.68 ± 0.19 cm) or longer (1.86 ± 0.3 and 1.85 ± 0.63 cm), respectively. In addition, 19 (43.18%) field‐collected samples of unknown origin were successfully identified to the level of species or group of species. Thus, to increase the efficiency of this identification key, the inclusion of more morphological characteristics (i.e. hair diameter and shape, cuticle index, cortex types) and DNA barcoding should be considered. Finally, the proposed identification key could be used as a simple and efficient tool for species inventories and ecological studies of targeted taxa in Central Africa.

Discovery of a new genus record for Paraguay, the Atlantic Forest endemic rodent Abrawayaomys (Cricetidae, Sigmodontinae)

2019

The mammals of Paraguay are still poorly known. We report a new genus for the country, Abrawayaomys, a spiny cricetid rodent endemic for the Interior Atlantic Forest. This record extends the distribution of the genus approximately 100 km, and west of the Paraná River. This addition increases the number of mammals in Paraguay to 184 and verifies that rodents are the most diverse group of mammals in the country. We outline identifying morphological characters of Abrawayaomys and elaborate on the significance of this finding for conservation and biogeography in the region.
