Calomyscus hotsoni

Hotson's mouse-like hamster (Calomyscus hotsoni ) also known as Hotson's calomyscus or Hotson's brush-tailed mouse is a species of rodent in the family Calomyscidae.It is endemic to southwestern Pakistan and southeastern Iran (Musser and Carleton, 2005; Norris et al., 2008).

Animal name origin

The species was named by Oldfield Thomas after John Ernest Buttery Hotson who collected the original 4 specimens in Balochistan in 1918. The species had traditionally been called Hotson's mouse-like hamster because of the presumed relationship between members of the genus Calomyscus and the hamsters. Musser and Carleton (1993) considered Calomyscus to be distinct enough from the hamsters to warrant a distinct subfamily. Numerous molecular studies (Michaux et al., 2001; Jansa and Weksler, 2004; Steppan et al., 2004) have supported the distinctive nature of the genus, and they are currently recognized as belonging to a distinct family, Calomyscidae (Musser and Carleton, 2005).

In order to underscore that members of the genus Calomyscus are not related to hamsters, Musser and Carlton (2005) suggested the name Hotson's calomyscus, using the genus name as a common name. Norris et al. (2008) agreed that the use of the term "hamster" should be avoided, but disagreed with the application of a genus name in place of a common name. Although they preferred the use of a local name, they reported that the languages of southern Pakistan do not distinguish among small rodent species (see haraam). Instead, Norris et al. (2008) proposed that the species be referred to as Hotson's brush-tailed mouse, identifying a major morphological feature of the genus. Jordan et al. (2008) have since adopted this as the primary common name, but also list Hotson's mouse-like hamster (but not Hotson's Calomyscus). As with most species of small mammal, common names are rarely used outside of checklists and field guides, and most researchers employ the binomial name, Calomyscus hotsoni.
