INTEGRATIVE TAXONOMY OF THE MOUNTAIN CAVY GALEA MUSTELOIDES MEYEN, 1833, A HIGHLAND NEOTROPICAL CAVIOMORPH RODENT.

The mountain cavy Galea musteloides Meyen, 1833 is a terrestrial caviomorph rodent with diurnal and colonial habits. It occupies grassland areas and rocky shrub steppes in the arid highlands of the central Andes of western Bolivia, northern Chile, and southeastern Peru. Recent phylogenetic studies based on the analysis of mitochondrial DNA showed that this species has a genealogy geographically structured into two main clades, one encompassing those populations usually referred to G. m. auceps (Thomas 1911) and G. m. musteloides, and another referable to G. m. boliviensis (Waterhouse 1848). Multivariate statistical analysis of 16 craniodental measurements corresponding to seven geographical groups supports this conclusion, allowing us to recognize two subspecies within musteloides, for which the names of musteloides (including auceps) and boliviensis (including G. monasteriensis Solmsdorff, Kock, Hohoff, & Sachser, 2004) are available. Due to some uncertainties in the original reference, we also restricted the type locality of G. musteloides to Pisacoma, Puno, Peru. [ABSTRACT FROM AUTHOR]
