The highlands punaré (Thrichomys inermis) is a caviomorph rodent of South America from the spiny rat family.[2] It is endemic to gallery forest, savanna and rocky outcrop habitats in Bahia State within the Caatinga ecoregion of eastern Brazil at elevations from 260 m to 1030 m.[1] It sometimes nests and often takes refuge in crevices in rock formations, as means of both predator avoidance and moderating temperature extremes.[3] The species tolerates a degree of habitat disturbance. Although hunted, it is considered common throughout its range.[1] Its karyotype has 2n = 26 and FN = 48.[2]

The etymology of the species name corresponds to the Latin word inermis meaning unarmed, defenceless — itself constructed from the prefix in- meaning without and the stem arma meaning defensive arms, armor —,[4] and refers to the soft fur of Thrichomys members replacing the spiny hair of the other genera of Echimyidae.[5]
