Highlands punaré
species of mammal
The highlands punaré (Thrichomys inermis) is a caviomorph rodent of South America from the spiny rat family. 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. It sometimes nests and often takes refuge in crevices in rock formations, as means of both predator avoidance and moderating temperature extremes. The species tolerates a degree of habitat disturbance. Although hunted, it is considered common throughout its range. Its karyotype has 2n = 26 and FN = 48.
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 —, and refers to the soft fur of Thrichomys members replacing the spiny hair of the other genera of Echimyidae.
This brief starts where responsible research should: with the source description of “Highlands punaré” as species of mammal. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of mammal. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Oct 4, 2025. The linked authority identifier is Q1764000. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1030.
Scientific names, classifications and consensus can change while older terminology persists in catalogues and historical literature. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
