SPECIES Calomys lepidus
| Author: | Thomas, 1884. | | Citation: | Proc. Zool. Soc. Lond., 1884: 454. | | Common Name: | Graceful Laucha | | Type Locality: | Perú, Junín Dept., Junín. | | Distribution: | Altiplano of C Perú, through W Bolivia (2950-4820 m), to NE Chile and NW Argentina (Jujuy, Salta, and Tucúman; Díaz, 1999; Ortiz et al., 2000a). | | Status: | IUCN – Lower Risk (lc). | | Comments: | Revised by Hershkovitz (1962). Populations in Jujuy, NW Argentina, exhibit a different chromosomal complement (2n = 44, FN = 68), as reported by Espinosa et al. (1997), from those described from Peru (2n = 36, FN = 68) by Pearson and Patton (1976); Espinosa et al. (1997) offered a Robertsonian explanation to account for such the karyotypic differences between chromosomal races of a single species, but also acknowledged that two species may be involved. Anderson (1997) regarded carillus and ducillus as valid subspecies in the Bolivian Andes. |
